Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Tutorial

Control the position of a RC (hobby) servo motor with your Arduino and a potentiometer.

*** I recommend! You not connect directly the servo motor to arduino. I suggest you use external power to the servo.

SG90 Mini RC servo motors can be used. This can damage the Arduino MG996 instant high torque.

MG996 Stall Torque: 9.4kg / cm (4.8V) - 11 kg / cm (6.0V) and Operating voltage: 4.8 ~ 6.6v.

I wanted to tell in this tutorial; connections, code generation and motor control. So I did not give more details about the engine.

Step 2: Hardware Required

Hardware Required

  • Arduino or Genuino Board
  • Servo Motor
  • 10k ohm potentiometer
  • hook-up wires
  • mini breadboard

Step 3: Circuit

Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino or Genuino board. The ground wire is typically black or brown and should be connected to a ground pin on the board. The signal pin is typically yellow or orange and should be connected to pin 9 on the board.

The potentiometer should be wired so that its two outer pins are connected to power (+5V) and ground, and its middle pin is connected to analog input 0 on the board.

Step 4: Code

This example makes use of the Arduino servo library.

Question 1 year ago

i made it but to power the servo i used a bread board power supply module , it didnt work.If i plug in the servo to the board the power of the board is gone , the coding is correct

hi my friend I want to make an rc transmitter & receiver 4ch or more by using 2 arduino one send the positions of the servos and the second receive and output the pulses for each one and by the serial connection ..... any ideas ^_^ I will be thankful

I want to simulate an rc transmitter & it's receiver I'll us rf module to connect
in the first arduino we'll connect the 4 potentiometers and in it's code we'll send the tangle by the potentiometer reads to the specific servo and in this case we have to send two values for each servo first one is the tangle and the second one for witch servo we are moving
then we have 8 value to send so do you find this way food to build or you may have another way to program ...
