Some of them are your vacuum cleaner, hairdryer, elevators, electric windows in cars, etc. DC motors are used widely in many places.DC motors have no polarity (Unless marked with + or -), which means you can reverse the direction of the motor by swapping the two wires.When current is passed through, opposite polarity between the two magnetic fields inside the motor causes it to spin continuously in one direction until the current stops.Correspondingly, the motor that uses AC power is an AC motor It is a motor that can convert electrical energy into mechanical energy in order to run. DC Motor refers to a rotating electrical machine that converts direct current electrical energy into mechanical energy.Therefore, all servos will work together without any interrupt. LARGE SERVO MOTOR ARDUINO CODEUse the Arduino code given below to program your Arduino and connect all the Servo Motors as shown in the circuit diagram with proper power supply to Motors. To use the external supply you just have to short the Arduino ground to external supply ground. 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.
