2 servo motor arduino code8/13/2023 For External Power supply you can use Adapters, RPS (Regulated Power Supply Instrument) or good quality 9v volt batteries, evne you can use your laptop USB port for powering small Servo. The only solution to this is to connect an external power supply with appropriate amount of current rating (in this project I used 2A with 9v supply). We all face current problem while using more than two servos with one Arduino. void setup() Ĭontrolling Multiple Servos with Arduino- Working: Using a Servo with digital pins of the Arduino is not reliable. You can change the pins according to you but keep in mind that it should be a PWM pin. As shown in the below code, Servo1 is connected to the 3rd pin of the Arduino. Then, we are setting all the servo’s input pin with Arduino. Servo servo1 Servo servo2 Servo servo3 Servo servo4 ![]() In below code, we are initializing all the four servos as Servo1, Servo2, Servo3, and Servo4. So here we are starting by defining the library for Servo motor. The complete Arduino code for Multiple Servo Control is given at the end.Īrduino has library for Servo Motors and it handles all the PWM related things to rotate the servo, you just need to enter the angle to which you want to rotate and there is function servo1.write(angle) which will rotate the servo to desired angle.
