On/Off switch
Note - Lighting on/off remote control is one example of what an
output relay may switch and control.
Note - An external Pullup voltage connection is recommended when connecting GPIO sensors to the M1.
When a sensor does not provide more than 2V, the Pullup provides an appropriate high level reference for the M1's input.
