The author found that “Tower Pro Micro Servo – SG90” motors were prefectly suitable. The two servos (Left and are Right) are driven by the D6 and D5 outputs of the Arduino, in connection with the ...

Among these are the Serial Servo Raspberry Pi HAT, the Serial Servo based on ESP32, the Serial Servo Pico HAT, the Serial Servo Arduino Shield, and the Serial Servo Breakout.

An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver.

A selection of different sized servo motors. By Osamu Iwasaki Servomotors usually have three connection wires: a power line, a ground line and a signal line.
