Really nice tutorial! I want to control my home stereo amplifier with an android app and MKR1000 seems perfect for that! Also thanks for the tip of using the MIT compliler for the app itself!
Great concise, practical, useful tutorial.
Thanks, my project worked after watching this Video!
Nice short precise video, thanks. Explained a lot.
You're an impostor
Thank you sir. What are the minimum prerequisites for undertaking this project? I am comfortable with using the sockets library and proficient in C and C++ in general, and I know a little about mobile development.
Very Thanks! Objective video and your explanations too! Congratulations!
Reallly beautiful tutorial...
Awesome tutorial. Thank you so much!
I use Esp01 for this tutorial. Due to no analog port in Esp01, I use some words instead to show in webpage. But cannot show the word on webpage
Well, it seems to bo greate. I can,t wait for the delivery of my wifi shield and check it out. Tkanks a lot for that tutorial :)
Awesome video, extremely well explained!
Excelent tutorial!
Perfect tutorial thanks a lot.
Hi,
i have a question.
can we use something.local/ledoff ? can we replace the ip?
using android code ? it is working on the ios devices and also for windows i have downloaded bonojour.
hye..i have done this tutorial with wifi shield..but i dont know how it works..when i open the serial monitor there is only blank space appear eventhough i have disable all the //.. and when im press the button, the Led also display nothing..pls help me
I made a arduino code for a humidity sensor but without the wifi algorithm. Should i just copy paste it or do i need to change within it?
hey anyone know how to send strings using this ? stuck on a project. Thanks in advance,
can i control arduino from anywhere using the internet ? using this app ?
Thanks for this wonderful tutorial. I was looking for this. I just set the static ip address for the Arduino in the Arduino code and it worked fine. But y r u connecting the jumper wire ? My code working without the jumper wire.
The jumper wire is connecting the power supply to the ADC input to give you a full scale ADC reading (that is why the app is showing 1023 for a full scale 10 bit reading). The code will work whether the jumper is connected or not.
hello can you send me your android code please !!!!!
There is a link in the video description that will get the .aia Android file
The dropbox download link for the Android App .aia file is not working. Could you please re-upload? Thank you for this great tutorial. It's much appreciated!
does this steps for CH340G Uno Board ? or it permissible for MKR1000 board only?
can you help me with my project? the data captured from Arduino devices(Arduino IDE) I want it to send to the mobile application / these data are from ultrasonic sensor and dht 11 (range and temp/humidity) thanks sir
Im also trying to build same kind of app..i too need help :(
Great tutorial. I was just wondering about the safety of such connections, static IP adresses and hard-coding WiFi passwords onto arduino... Would you comment on that?
Great question. This video was from multiple years ago, I believe it is just meant to work on your local network (local network meaning your router at home or office). Setting static IP addresses does not affect the security of your local network because IP addresses on your local network are not visible to the outside internet, outside internet can only communicate with your router's IP address. Unless somehow your router is hacked, the outside internet can't see IP addresses on your local network. As far as the hard coding of the WiFi password, that is a security risk if you share your code. Remember this is just an example application. If you are making a product or something for others to use you would not hard code passwords. All my videos are meant to be simple examples not finished products.
Hello, thanks for your efforts but i would like to know if i have the source code of an Android app that has a lot of customized functions and i need to build the interface part with the ESP8266, what is needed and how can i connect the app with ESP8266 (what protocol and library)
Thanks in advance

Hi, you showed how a char can be transferred when a certain value is expected on the Arduino side. I would now like to transfer an integer. I won't be able to do that with the "endsWith()" logic. Do you have any ideas what I could do instead?
I made this video years ago so I don't remember the details in the software. If I am using a standard library for the data transfer in the code you should look at the functions in that library to see if one handles integers. Or you can convert chars to integers and vice versus. If an 8 bit char is represented as an ASCII character from 0 to 9 you can convert it to an 8 bit unsigned integer from 0 to 9 by subtracting 48
Does the Nano 33 IoT require a shield? Also wondering if the pre-made apps are required, or if somebody could just make a React app/simple web interface from scratch (designing the UI would be kinda fun, with HTML/CSS/JS. Event listeners, radio buttons and whatnot.) Thanks!
I did not test this example code with the Nano 33 IoT so I can't really answer. If the code does not compile for the Nano 33 IoT then it will not work and needs to be modified
Plz i need your help for ios app ??
Can you help me to build ios app to connect iphone to arduino ??
How can I make the Arduino read a number between 1 and 100 from a text box instead of the letters "H" or "L" , will I have to make 100 conditions in the MTI App or there is a easier way to do?
A text box will return text or ASCII characters so you either need to change the text box to a UI object that supports numbers or you will have to convert ASCII number characters to real number values
Can we do with Android Studio?
Would this work relatively the same if I used Xcode instead of app inventor?
Not sure I understand this question. Yes of course Xcode supports WiFi based apps
@ForceTronics can i use my airport express router (iphone)for this so i can modify it that i have light control +music tru a app on my phone?
Not sure I follow your question. Your phone and Arduino device must be on the same local network (same router). If there not you typically would use cloud storage in between
Everytime I run the MIT App Invenrtor 2 on my mobile phone, it always scanning qr code. How can I permanently store my project on my mobile phone ?
The MIT App Inventor II website provides instruction on how to do just that
how do i connect wifi to ardunio and mit
how much meter it will control can we control a drone
what type of shield can i use?
Can i see the android code from the aia file ? i build the whole app and i still have to make the connection.
can i implement the same code on android studio ? thank you
There is a link to the file .aia file in the video description. This file will only work in App Inventor II to the best of my knowledge
It would be nice to take the router out of the loop if you can make the Arduino and phone the only components in the network so you could go on the road with this.
is this code will work on esp8266??
can u make a tutorial for control relay firebase with esp8266 working on android app
Is it possible to setup and then control from your phone where WIFI/router/internet wouldnt otherwise exist? So like in a field direct from phone to arduino?
You can use a bluetooth module for direct connection between phone and arduino.
Can you tell me if this code will work with the CC3200 LaunchPad board from TI? I think it need differnt libraries but I'm interested if the same Android app that you created will work with the CC3200. Thank you!
If you can use the HTTPS protocol with the CCS200 then the app will work
can you connect it via mobile network
Can we do this but with a GSM sim and not inside a wifi network
sir, kindly tell me how to do this if using Arduino Mega 2560 board?
Hey! That's a great tutorial. But my question is can I use the same code with minor changes to trigger relay for controlling motor instead of LEDs.
Yes. The LED was just meant to be a simply control example with app and WiFi. You can modify as needed for your application
@@ForceTronics Can I use NodeMcu in place of Arduino MKR 1000
@@sohaibarif5996 I believe they use different WiFi libraries so you would need to change the code
Bangladeshi?
hey thats my router!
Hi, do you know how I could do exactly this but with an FS90 micro servo instead of an LED?
The goal of this video was to show how to add wireless control to a design. The LED was just used as an example. If you want to use something different than an LED that's beyond the scope of this video. You might want to find a tutorial on the fs90 micro servo and then combine what you learned there with my video
Hello.I want to know ,android connect WiFi, How much distance is it?
The Android operating system does not determine WiFi range. The hardware it is running does. You would have to check the specs of your Android hardware. There maybe common standards for smart phone wifi range, but if there is I don't know them
How can we access Arduino using another Arduino for accessing rather than using the phone, like having an Arduino send message to another Arduino through the internet, like using the Arduino as a remote controller
I don't have a video on that topic, but I am sure if you search TH-cam or the internet you can find a tutorial that will help you out
which kind of board i have to chose in my arduino software?
In the example I use the MKR1000 board. You should be able to use any board or shield that works with the WiFi101 library.
It was a very very useful tutorial 👍 thanks for sharing.
Please post more tutorials with mkr1000.🙏
Hi, how do we control the arduino MKR1000 using the android apps that we created in the android studio ?
I don't understand your question, isn't that covered in the video?
@@ForceTronics he meant if he didnt use MIT but used arduino studio, how can he control the MKR1000
can you control your wifi enabled arduino from everywhere as long as it connected to internet?
Yes
great video, good explanations etc. yet can you make example with esp8266, that would be amazing
Anyway to do this connecting directly to your phone instead of through a router?
That would be a Bluetooth use case versus a WiFi use case. Unless the device you are connecting to is an access point then this will not work. I would suggest researching WiFi and Ethernet network basics to understand the benefits and limitations in these types of networks.
I tried to connect my mkr1000 to the wifi and I put in my ssid and password but it doesn't connect
can somebody help me
Maybe the port 80 in your wifi is not open
great work man !
can i connect arduino with mobile via wifi without a router ? because my project will be tested in a place without any routers and wifis ?
This series should help answer your question: th-cam.com/video/ZjjiHJS8lL0/w-d-xo.html
ForceTronics thanks a lot 😍
merci bro :-)
I can use this sketch to control an ESP32 instead Arduino?
No, different wifi libraries
Sir, could you check out the pard 007 and allow me to know how I can press forward to making an open wifi app?
If you could it would be highly appreciated.
android phone should be the server. How are you going to control multiple mcus
can this be used with a wemos d1 r1 board?
I am not familiar with the wemos d1 r1. If your asking whether the code is compatible my guess is no
Do you know how you could do this with Android Studio instead?
No I don't have code for the app that can be plugged into Android Studio
Can we use esp for connecting the arduino to the app??
Yes but you will need to change code since ESP uses different WiFi library
How about using ESP8266? Will it work using your code?
does it works with esp8266? or library are not compatible
I believe the esp uses a different wifi library so you would need to adjust code to handle that library
What should I do if i need to display value of temperature from temperature sensor in this app?..Anyone help pls :(
Based on the example showed, all you need to do is to hook up your temperature sensor where A0 is connected. Instead of having 5 V on A0 you should have whatever you are using for temperature measuring plus the proper scaling using the app inventor math functions. Remember that Arduino is only displaying the equivalent 0-1026 decimal value based on 0-5 V in A0, you are responsible for scaling that value based on your sensor temperature to voltage curve.
The arduino program logic and MIT APP program logic need to match?
I do not understand your question, please provide more detail on what you are asking. If it is a specific part of the video please provide a time stamp.
For example: I would like to write control logic(the pump base on high low levels to control on/off).
For the Arduino, I need to written pump control logic？
For MIT app block editor also need to drawings pump logic？
Base on the high low level signal to control pump on/off status, can you make a program code and seed to me？Or other base program code to learning. Thank
Yes you would to alter the code for both Arduino and the MIT app inventor to meet your custom needs. What I provide in this video is just meant to be an example for you to build on or customize for your own particular application. No I will not make custom code for you.
Please tell us if that is working with the ESP8622 wifi module arduino or not... thanks a lot
The Arduino code will not work on the ESP8622 because the MKR1000 and ESP8266 use different WiFi libraries. You can refer to this series to see an example with the ESP8266 th-cam.com/video/ZjjiHJS8lL0/w-d-xo.html
So, please, can you tell me, what is the libraries needed to do the same program as this video, but with an ESP8266 ?Thank's you :p
Go to the Arduino IDE and find the ESP8266 example programs. Those examples will show you the libraries to use. Also if you follow the link from the above post I show the libraries in a different video.
Thank's you ;)
ForceTronics thank's a loot
Just Awesome!
Thank you so much. You are the man.
Would you be kind and make a tutorial video on how to connect an AC well water pump to a relay?
If you could also advise on the correct relay spec to purchase please.
I plan to control my pump for the house from my cell phone using my Arduino UNO and a WiFi sheild.
AC Well Pump Specs:
-> 240 V
-> 50 Hz
-> 1.5 HP
-> 6.6 A
-> 2800 rev/min
-> HEAD: 30 Feet
If there is anything else you would need to know, kindly let me know.
Eagerly awaiting your reply.
Thanks & Best regards,
Philip
I am glad you enjoyed the video. I typically do videos that are related to projects I am working on so I don't think I will be doing a tutorial on your exact application related to an AC well pump. Good luck on the project.
Sure, no worries...just trying to get all the help and advise I can.
Maybe at the least you can advise me on just what spec relay is suited for the pump spec I mentioned?
Thanks,
Philip
HI, I'm currently working on a similar type. Have you made your project? If so pls leave me a mail on pranavdeep1997@gmail.com
Thanks in advance :)
hey does controlling the card via wifi works in long distances?
I am not sure I understand your question. But WiFi has a range (often dependent on the router you are using) and if you are beyond that range you can't use WiFi. You can use the cellular infrastructure as long as you are in range of a cell tower.
@@ForceTronics ah so to cover that problem i can put a mobile rooter fixed on the robot. and i connect to another rooter and send the commands via the IP adress of the robot. I can do that right?
Nice tutorial
Q:will it work without mobile data, Just using mobile wifi Hotspot?
Yes you can use WIFI
i have solution to static ip address in esp8227
can we send image from esp8266 to android ?
I am sure you can but you will need to research the best way. If there is no existing software library then it will probably take some work to create your own
You can do it on Android with Arduino Studio app.
can i use this with esp32 cause my project does not used arduino
This example was done in the Arduino programming environment. If your using a different programming environment then you will need to change the code
@@ForceTronics so if i want to change code...do u have example code for esp32
and is arduino has a wifi module?
then I connected it to another wifi and it worked
can i ask for the code in the arduino ide please?
Link to the code on my blog is in the video description
how to send serial data to arduino??
There is no virtual Serial port over WiFi as far as I know (if you find a way let me know). There is a virtual serial port for Bluetooth
and how to find the ip address of that esp8266 device ??
👌
how to do that with arduino uno and wifi shiled ??
this tutorial uses the same WiFi library that is compatible with both the MKR1000 and the Arduino WiFi Shield so this code should work with the WiFi Shield. But I don't own the WiFi Shield so I did not test it with the Shield and I cannot answer any questions related to the WiFi Shield because I am not familiar with it
just open a port on your router
Newbie here sir! Does this code will word for wifi modules?
I am not sure what WiFi modules you are referring to
Esp8266?
btw. Thanks for the response sir!
No the ESP8266 uses a different WiFi library then the MKR1000 and WiFi shield. You would have to go in a change the libraries and possibly how some of the WiFi objects are used. I have various videos that show example code for the ESP8266 in this playlist if you are interested: th-cam.com/video/ZH7ufemP8e0/w-d-xo.html
Oh Ok sir! Im just starting to study arduino sir. Thank you so much sir! I just want to control a servo using mobile phone ( Mit app inventor.)
where the wifi code i can't download it doesn't works
I just tried both links and they worked fine. Not sure why they didn't work for you
That MKR arduino looks like ESP32
wheres the code??
If you are looking for the Android app code there is a link to it in the video description. If you are looking for the Arduino code follow the link to my blog (link is in video description). If you are having trouble finding the blog post with the code use the search function and type in the name of the video to find it.
how to find the wifi IP?
If your router has a built-in web page you can get IP addresses for all connected devices there
If your router has a built-in web page you can get IP addresses for all connected devices there
Thx for no music
All links broken as per usual
Really? I just tested both the links in the video description and they worked for me
please con you send me your email , if it's possible?
dont be exited .we have to scan qr code when u close that apllication .how long will run that app in our background.waste of time read something useful
You only have to scan QR code during development. Once your done with the development work you can convert it to a standalone app. Please don't spread misinformation
Really nice tutorial! I want to control my home stereo amplifier with an android app and MKR1000 seems perfect for that! Also thanks for the tip of using the MIT compliler for the app itself!
Hello, if i wanna sent character 's' to the arduino. how should i make the blocks?
Just do some basic tutorials on MIT App Inventor and you will figure it out
