Command : servoWrite
Parameters

• pin: It is the Bolt GPIO connected to the servo motor that you want to control. It can take any of the following values 0, 1, 2, 3, 4.
• value: It is the angle to which you want to set the servo motor. It can take a value between 0-180. NOTE: Some servo motors may not be calibrated, and may give a different output angle than expected.
• deviceName: The name of the Bolt device you want to control.
