| PWM: Servo motor |
| ################ |
| |
| Overview |
| ******** |
| |
| This is a sample app which drives a servo motor using PWM. |
| |
| This app is targeted for servo motor ROB-09065. With the PWM control signal, the |
| servo motor can rotate to any angle between 0 and 180 degrees. The corresponding |
| PWM pulse width is between 700 micro seconds and 2300 micro seconds. The motor |
| is programmed to rotate back and forth in the 180 degree range. |
| |
| Since different servo motors may require different PWM pulse width, you may need |
| to modify the pulse width in the app if you are using a different servo motor. |
| |
| Wiring |
| ****** |
| |
| BBC micro:bit |
| ============= |
| |
| You will need to connect the motor's red wire to external 5V, the black wire to |
| ground and the white wire to pad 0 on the edge connector. |
