Connect the stepper motor’s coloured wires with correct output pins of the shield. You will need to connect the following pins to the servo using the three jumper wires: Feather GND to the brown or black servo wire. We have chosen to connect our stepper motor at M1,M2 terminals. Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. Then we will connect a stepper motor with either M1, M2 (port 1) or M3, M4 (port 2) terminals. With the circuit hooked up, load the following sketch. This video shows it working fine: // Libraries Because the servo is 'reading' a control signal from the arduino it needs to be electrically referenced to the arduino's voltage source, so the external power's ground should wire to both the servo ground pin and a arduino ground pin. The first step is to mount the L293D motor driver shield on the Arduino board. ![]() The servo motor is Tower Pro SG90 purchased at Amazon a. The servo motor has just 3 wires, two of which are GND and 5V for powering, and the third wire is the control. The only thing I changed in the setup is the power cables but then I changed them back and the issue persists. Arduino material continuously, but this time I tried to move the servo motor with Arduino Nano. Unlike other motors, servo motor is very easy to interface with Arduino or any other microcontroller due to its built-in controllers. Using a servo motor with Arduino is quite easy. Earlier, it worked perfectly fine but since then, I've change the electronics set up a little bit and now they just go crazy and the only way to stop them moving is to cut the power. The ground wire is typically black or brown and should be connected to a ground pin on the board. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. Servo motors have three wires: power, ground, and signal. Every time I boot up the board (DFRobot Bluno) the servos start moving without me telling them to.
