| 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. |
| |
| Arduino 101 and Quark D2000 CRB |
| =============================== |
| |
| You will need to connect the motor's red wire to 5V, |
| the black wire to ground and the white wire to PWM 0 via |
| the shield. |
