Thank you so much for making this video. Well explained!
You are welcome.
thank you,i made this project with 4 servo motor using this method and it worked really well!!
Glad it helped
bro can you tell me how you added 4 servo plz
Nice video, thanks for the clear explanation.
You are welcome.
Please show us how to use buttons or 3x4 numeric keypad to control 16 servos!

Thanx Robojax!
You are welcome.
really nice and helpfull video
Thank you.
Hello Ahmed Thanks for the advice in the other videos. the power supply with batteries for the nano and the servo motor works perfectly. Now I would like to ask you how I can move the servo to the right with just one click and to the left with just one click. as in this video with two buttons.
Hello, see my other video as I have such video
I would like to run a few brushless motors and servos using if and else statements from the same Arduino Mega board making use of a push button. How would I go about doing that?
You will need Elecyronics speed controller or ESC to control ruthless motors.
I have that no problem . My question is would I be able to?
@@robojax
Ur just cool n awesome. Thank u for the tutorial.
Can we add a reset button to return the position to zero degree ?
You are welcome. Yes you can.
Define reset button (as RES) the same as LEFT and RIGHT. in setup do the same
then if (digitalRead(RES )==LOW)
{
myservo.write(angle);
}
Angle is the variable you define at initial step value.
Robojax thank you so much for your quick reply. I will try and let you know.
/*
Controlling a servo with two Push buttons with Arduino
when Left push button is pressed, the servo start moving to the left until it reaches 180( or zero) degrees
when Right push button is pressed, the servo start moving to the right until it reaches 180( or zero) degrees
At any instance if the button is released, servo stops

Thank you in advance.
Great video and explanation. I have been looking for a solution using two buttons for a model railway turnout. Is there a way setting it to go directly to an angle with one button and then back again with the other button? I have seen it using a command called throw?
I have so many videos on servo and I am sure one will work for you or watch and learn and combine two of them. here is the link th-cam.com/users/RobojaxTVsearch?query=servo or just search my channel for the word "servo"
Oh dang! That’s why I’m here! Lol!
Is there a way to make this work after removing the wires/making the wire distance longer?
If you are referring to push button switch wire, yes you can extend it with shielded with to 100m and with unshielded wire perhaps to 2 minutes I 3m depending on environment and type of wire.
hi, great video! I wanted to know whether the 2 button code would remain the same if I used an external power source for the servo, like a 6V battery, attached by wires to the breadboard? Please could you also upload a clear wire diagram for the set up of 2 buttons?
Wrong video. If you follow my course you would know it. This is way advanced comparing to basic servo control
See the lecture from my Arduino Step by Step course th-cam.com/video/J_kbyAY1rLM/w-d-xo.html
@@robojax thank you for your help, I shall check the video :)
Watched your video and my project works the same as yours. I could use your help and experience as I am very new to working with Arduino. I would like to know how to control two servos, each with two buttons.
Please see my all videos on servo here and you will find something that will work for your application th-cam.com/channels/kcBSig_Iu4ZnAIeCeG1TVg.htmlsearch?query=servo
Hi, how can i do this but: the buttons act as toggles and button1 set it to stay at 0 degrees and the button 2 to 90 degrees?
Hey Robo jax, great vids. However I'm losing my mind as to how to do this with the 16channelpwm drivers. I'm sure you're busy but if you can point me in the right direction thatd be great. Thanks again
Hi, why are you trying this code which is for 1 servo motor and using it for 16 channel? Search my channel for 16 channel th-cam.com/channels/kcBSig_Iu4ZnAIeCeG1TVg.htmlsearch?query=pca9685
Thank you for the video. Very helpful. Can you help me please, I need a servo to cycle from 0 degrees to 180 and then back, when a button is pressed. So, when I press a button, the servo will go from 0 degrees, to 180, then back to 0.
You are welcome. Can you tell me why you need? what kind of application requires that? I will make video on that if I find it useful.
Thank you for your reply sir.
I want to build a machine like this th-cam.com/video/slg8Mn1qwE4/w-d-xo.html
But I want my machine to be electronic vs mechanical.
Hello, great video. I'm wondering if you could help me. I'm trying to figure out a way to press the button once (not hold the button) and have the servo move from 0 degrees to 180 degrees, delay for 5 seconds and then return to 0 degrees. Any suggestions?
Search my channel. I have so many set it related videos. Watch, learn and write your own code. It is impossible to satisfy everyone’s need. I have explained them fully. So watch 2, 3, r or 5 times until you learn it and write your own code. Good luck
Hello Robojax and thanks for your interesting video. Please I have a question for you about another video you made (Sound module ISD1820) Please can you tell us what is the potentiometer value and how to connect to the ISD1820 sound device and match the audio level? A schematic drawing wiil be very well received. Many thanks again and have a nice day!
Hello and welcome. would you please post your question here th-cam.com/video/IfK8z_o5vbk/w-d-xo.html so I replay?
Hi Robojax and thanks for your kindly reply. Yes I made this question in the video about ISD1820 sound device you say me. I will be very grateful if you could answer my questions there. Thanks for your help and have a great day!
Yes I posted there my question. Please I will be very grateful if you could answer me there, Thx!
Nice video.....can it use for motorcycle gear selector ?
Yes, definitely
@@robojax motor respon time need adjusment, right?
Thanks
does this work for a winding and measuring system project if i use this code for the motor? or its different for all proejcts
this code is about controlling a servo motor. if you use servo motor, then it will work.
hi do you any video Control Servo motor with push 2 buttons with OLED display?
Anyway nice video it's help thank you for sharing

@@robojax hi there thanks for your reply! i will try to learn it! i never touch programing before :-)
Sir Ahmad ,can you please explain how to modify the program if ONE MORE SERVO is added in order to execute the same action (turning to certain deg and returning to same position when the pushbutton is released)
Hi, I have separate video for multiple servos. Check all videos on Servo here th-cam.com/users/robojaxTVsearch?query=servo
Hello Robojax, would you please show me how to increase coding from 1 servo to 6 , I find your videos very interesting, thank you.

Halo, awesome video, I do have some questions, I want to use 4 servos each using 2 buttons, what I'm experiencing is my servos are conflicting, I have define each button to a pin and servo would it because all my servos are on one ground to the arduino? And maybe can you leave a example to use 2 servos on 4 buttons I just want to make sure I'm correct with the code I'm using if you don't mind?
Hello, Thank you. Please post your code in this page codeshare.io/29njmB and I will look at it.
@@robojax ah thanks man I managed to sort it out it was in the code, keep an eye out will post soon
@@pieterfouche6931 hey man it would really be helpful if you could provide me with your code because even I want to use 4 servos each using 2 push buttons. I want it for a college project.
Good morning what is cheapest arduino board to control servo by two buttons? Is it need servo controller like pololou micro?
Arduino is already $3 or $4 on aliExpress where you get it in 30 to 60 days with free shipping. any arduino can work with servo.
Good afternoon Robojax,, after watching the video "dual button to control micro servo" I have tried to modify code to allow me to control six servos individualy, twelve buttons, unfortunately
I'm failing miserably. I would be most thankful for any help I could get to get this write so I can get my trains going Thank you very much.
I was on vacation for 2 weeks. Replaying now. I would have to make video and write/test code which needs time. I will put it on my "to do " list.
What would I have to add to the code if I wanted to have the servo only move the determined increment no matter if the button is quickly pushed or held down. Currently if I hold the button down the servo continues to move.
See the links to other codes in description. Or search and I am sure if you watch them, you will learn and customize them for your need
Hello i have a problem.
I have 2 buttons and one start move servo, but second should stop this moving. How can i stop servo moving?
Mr Robojax is it possible to prepare software to sevro control with features: power on- go to 0 , push button(non momentary button) - servo start moving with pre loaded anlge, delay ( pause time as add setting), servo stop- delay( pause time as add setting). Just servo moving in loop (0-45 degree )with paused. Is it posible to get 3 different speed via second button?( Micro 6 Pololou controler possible)What is price of it - if You're agree to do something like that. Regards.
Hello, I did not get it properly. The best way to explain it is to use machine state diagram something like this snipboard.io/IgYnWr.jpg and contact me via Robojax.com contact page. Please provide your email address in the message. I will charge $75/hour.
hello! i am trying to move between two specific degrees, 155 to 180. i have tried changing the degrees in the code but it causes it not to work. is there a way to adjust the code so i am moving the servo less?
Hi, that's exactly what I have written he code for. you must have changed the code. start with the fresh code and pay attention to const int minAngle = 0; const int maxAngle = 180;. Or check tones of other code for servo that I have on this page robojax.com/learn/arduino/
thanks for helping us!
ahmad i need a code to work a servo with just one buttone when push and release the buttone the servo go to 90 degree and back to 0 degree! i believe it is simple code but im just new to arduino so can you please help me? thank you so much ahmad

@@robojax thank you so much
you are welcome.
Sir for controlling the movement of 7 servos using 4 buttons. How the connections will be done?
If you watched my video. I never leave any details. You will need to define extra pins for push butts and extra pins for servo and add the rest of the code. It should work. Watch the video again without escaping.
in the 2 button coding, i want the servo to go back onto its initial position which is 90 if we release a push button, so can you tell me that what do i do. or if you can make a video on this topic so this will be very great.
I have got a video showing how to control servo motor using Infrared Remote controller. You can use the code if you know how to modify it. th-cam.com/video/Wp7hX9UErSQ/w-d-xo.html
I tried to understand that code but was not able to understand please tell us how to do it , please make a code for this problem please
Can you change the int angle = 90 to start from where ever it’s location is at that moment?
yes. I have explained this in the video. Change it to any value between 0 to 180.
Robojax but setting it at any value between 0-180 will set that servo at that value when restart. For example, if I leave the servo at 75 degrees (or any other random degree)I would like the servo to stay at that position when I restart it and not at the set value. Hope that makes sense.
sorry I did not get what you want to say. Setting value and "staying at that position" isn't the same if you don't push any button, it will be the same.
Robojax lol nvr mind
Hi, I am completely new to this and I am starting from knowing nothing. How does copy and paste work when trying to copy the code into the IDE. Each time I have tried and then compiled the sketch quite a few errors occur and the upload will then fail. any advise you could give would be greatly appreciated
Hello, please watch this 30 minutes course th-cam.com/video/Mbb2xa1WcRM/w-d-xo.html
hey im using the code with a continuous servo (360) and even if i release the buttons it keeps moving, how can i make it stop when i stop pressing the buttons? i thought about setting the input without pullup and using a resistor but im not sure.
I have separate video for that th-cam.com/users/robojaxTVsearch?query=360
What changes I need to make in code for makeing it like, once the left button is pushed servo should move left then again automatically come back to 90 degree when there is no input applied ...PLZZ help
the possibilities are endless for what each user want. I have created so many videos which you may find one of then useful or watch, learn and customize them. here are the videos th-cam.com/users/RobojaxTVsearch?query=servo
what would be my power supply for the servo motor
didn't I show it? it is 5V if you use the type of servo motor show in the video. Elese the manufacturer should provide the manual for the servo.
Hello sir can you please tell me how I can control 4 servo motors with one arduino
thankyou
Hi, I mentioned everything in this code. See the same video which is part of my Arduino course in this channel where you will see better details and wiring diagram. Simply define a push button pin for 2nd and 3rd servo, and the. Same for servo and all variables I mention in code . For example we have variable called “angle” in the code in this video, then you create new variable called angle2 for 2nd servo and angle3 for third. Or start learning Arduino from here th-cam.com/play/PLHvJ4bw0xno4Z3FC2W07I4D2UP14bOaT2.html
RJ, thank you for sharing. I'm trying to play around with the anglestep, going from 5 to 10 to speed up the rotation, but when I compile and upload, the buttons become unresponsive. The monitor shows the step have increased, but the servo doesn't move anymore. When I go back to 5 steps, all works. Seems nothing outside 5 steps is working for me? Any ideas?
Just had a thought...I pushed the button and then manually gave the servo arm a nudge, and it worked. I heard that some higher torque servos should be run with power supply separate from the Arduino. I think that may be the problem.
No, still sluggish or unresponsive at times. Maybe the breadboard? Do you have any sluggishness when you run the program?
I belive it is your servo itself. Try printing the values on the serial monitor. If it prints properly, then the servo is bad or bad wiring
@@robojax Values are printing properly. I suspect the wiring and will redo it with a different board and components. Thank you for this and getting back to me so fast. Subscribed.

why do we not need a resister? I see always resistors when arduino is used with push buttons. I don't get it.
because the input pin must have a state either HIGH or LOW. Push button when not pushed is not connected and the input pin will not be connected and this will cause unknown input value and as a result unknown output or result will occur. So we use a resistor when the button is not connected, using the resistor the input pin is either HIGH or LOW depending on how you connect the resistor.
