Hey
Tech at home
Can you make products for my company ?
I waiting for your answer.
You can send mail on : deepakhd20@gmail.com
Unfortunately the app link does not work and the app is not available in Play Store.
The drive link provided in the description is working for me, tried in different systems.
You can send request on our mail: deepakhd20@gmail.com
please How do i get the same app to download, I don't get the app if I download it, please how
In Play store I couldn't find the app now.
I have given APK download link from description. You can use that.
Exceptionally good video on this topic. Great content. 🔥💯
Thank you ❤️
Why we don't connect state and en pin and is it will only work or the bluttoooth module will get power when code is uploded
I want an app which the sends Mobile notification as a command to hc-05 bluetooth module .please help me anyone
Hello
Santosh
Hello how is possible to connect wirelessly the pins of MAX7219 (CLK, CS, DIN) to Arduino pins? So that there's no more physical wires that connects between MAX7219 and Arduino. Thank you.
Sir what's the resistance reading of your working hc-05 if you make the state pin common and check all pins, do they have all the same resistance including vcc pin? because mine is not working and there is zero resistance between state pin and vcc?
your video is best.. I am absolute beginners so please tell me i glow more than one led lights at different buttons
Similar to tutorial, configure more buttons in the Android app by giving any of the characters.
Add more if-else statements in the code as shown and compare same characters configured in the app.

Hi, I've followed your and other tutorials. But in every case, hc-05 does not send data to the serial monitor. Even if everything is connected correctly, the code is correc.I removed the wire before the upload, the baud code on the serial monitor is the same as the serial begin and hc05. I even tried different applications, but none of them work. With some miracles i setted the module to slave.But didn't work either. Did you know what can cause this problem?
Same problem with me
Same problem did you find solution?
Try going to Android phone and clicking Bluetooth and connect the module
You fried your chip use a voltage divider with 1k ohm and 2 ohm resistor

The world's best teacher thanks sir
Welcome
Sir please send the code
Can u send mail: deepakhd20@gmail.com
how do we send from arduino to the mobile phone? Say 5 integer values from arudino to mobile phone

I can't install the app in my phone !
Search for apk on google and install.
Plz provide the link for the bluetooth serial controller app ,I couldn't find it in playstore
play.google.com/store/apps/details?id=nextprototypes.BTSerialController
@@techathome its not install and not show me app
Koi meri hc-05 module pe application bana de
You can use the same application shown in video. You can get APK file on google also.
Was this 65/66 feed in the device or is it in-built ??
Those are standard ASCII values for alphabets which, compiler will understand
@@techathome Oh..Thank You
Thankyou it is because of you ive learned... no other video on Internet explains like this thankyou so much
Thank you ❤️ for the feedback!
repe
Program pdf not opening
Can you send mail: deepakhd20@gmail.com
Thank you interesant
Welcome❤️
can i do the same thing with Arduino mega 2560
Yes you can. Just verify the tx and Rx pins once.
@@techathome Thanks sir
Welcome
Do we require resistor for the led ??
Pin 13 has inbuilt resistor,
It's better to add if using other digital pins.
Can you share app link..

@@techathome app install nahi ho raha hai
@@techathome thdi app isn't installing
in my case i have to connect the HC-05 to my Arduino mega 2560 but the problem that i can only either receive or transmit data from the Bluetooth serial controller even tho i did the wiring and the code for both RX and TX . can anyone please help me find the problem ?
same issue
It works perfectly
Even a 13 year old can do it.(bcz i am 13)
Thank you!
Why SoftwareSerial.h library not included
Because you're using the Rx & Tx Arduino pins, so they're made for transmitting and receiving info from external devices such as this bt module
Thanks sir
Welcome
The circuit diagram file when i open in chrome, that shows file has unsupported
Download it and extract.
You can connect multiple HC-05s with

hello how to turn on and turn off the led only one command .same for on led and same for off led
Use this code:
//TH-cam | Tech at Home
int led = 13;
int data;
int x=0;
void setup()
{
Serial.begin(9600);
pinMode(13, OUTPUT);
}
void loop()
{
while(Serial.available() > 0)
{
data = Serial.read();
Serial.println(data);
if((data == 'A') && (x == 0))
{
digitalWrite(13, HIGH);
x = 1;
}
if((data == 'A') && (x == 1))
{
digitalWrite(13, LOW);
x = 0;
}
}
}
Sir my mobile is not compitable to this app can u suggest another app plzz.!!
Download the APK from the link in description.
@@techathome That's what sir from that link only i downloaded but it is showing not compitable plz do something 🙏🙏🙏
Search on Google, you will get APK.
@@techathome sir my device is not compitable with that app plz sugest another app plzzz sir😢😢😢😢
Could I use it for bts ?
Logic flow remain same, but motor driver specific lines to be modified. You can refer code from this: th-cam.com/video/EnbkdrYQ0NE/w-d-xo.html
Hey i have a problem beacuse i can't find this app 😢

App not compatible with my phone @@techathome
my hc05 led is on but does not blink and is not discoverable what should I do?
Can u check Rx and TX pin connections
@@techathome yea the connections are fine the led is steady and on but not blinking
App isn't installing
Very good ❤
Thank you
No connection established
Compilation error: No connection established
i got this error please help
THANK YOU
Sir does this works with COM 3 port?
Com port number changes from board to board.
You can directly select the port which shows in your Arduino tools .
How to connect to mit app
You have to make app with bluetooth connectivity I think, But the one I have suggested is best with lot of options.
Thanks Professor 😊
Welcome 🙂
Thanks a lot

Excellent work!
Thank you!!
V nice
Thank you
Super
Thank you
@@techathome could you plz let me know the price for HC05 BLUETOOTH MODULE
It was around 250, When i bought 3 years back
@@techathome thank you sir
works great thanks bro ,could you do a video of how to use a slider to raise and decrease the speed of dc motor ,thanks
Welcome,
This will help you, but with buttons : th-cam.com/video/5JLXpp7_l-E/w-d-xo.html
what is the app you download, can you give me the link?
@@shahanweerakoon I've downloaded APK pure app then I did a search on Bluetooth serial controller and download it
Bluetooth serial controller App link: play.google.com/store/apps/details?id=nextprototypes.BTSerialController
@@techathome Thank you but playstore show "this app not available for your device because it was made for an older versions of andriod"🥲
Great tutorial it really helped me solving my issue!
I also had a question, how to make led blink when turned ON and stop blinking when turned OFF?
In my code when I keep pressing button on phone the led starts blinking and when releasing it stops
It would be great help if this is fixed since I am working in my project and this the only video that helped
Thank you!!
Cheers but what about the solution?
You want to switch on and off with two seperate button ryt??
I didn't understand your requirement
I got everything basic stuff I wanted from this video but now I want led to start blinking/flashing when pressed ON and stop blinking/flashing when pressed OFF from mobile app
@@dhruvgoswami6819 set your arduino code to blink the led when your button is high and stop the blink when the button is low thats it to blink a LED use arduino basic blink sketch
