A micro:bit, battery pack and micro USB cable, plus a suitable computer for programming. 1 small servo motor (eg a SG90 3,3v servo) 3 crocodile clip leads. 3 breadboard jumper wires. Step One ...

It features four servo motors, charged with rotating the arm ... The servos are under the command of a micro:bit microcontroller board, which itself receives signals from a second micro:bit ...

The custom servo can tune the endpoints, the center point, and the sensitivity. It also can be set to handle continuous rotation. A 12-bit encoder tells the microcontroller where the motor is and ...

For a better understanding and simple control (outside ROS) of the micro servo, see my other github project S90_servo_motor, or looks at other examples. To control the servo position it has used the ...
