Examples¶

The following are a list of examples for lib.xinabox.oc05.

Servo Position¶

This example positions a servo motor on channel 1 90° to the left and right from a centre reference point according to a user input. The serial console accepts 'l', 'r' and 'c' for left, right and centre respectively.
