Code: Select all

//
// D5 is used to select whether to publish to ThingSpeak or not
// D5=1 (pulled-hi) Do-not publish to ThingSpeak
// D5=0 (grounded)  Do publish to ThingSpeak
//
// D6 is used as an input to sense the operating mode
// D6=1 (pulled-hi)  Wemos invokes DeepSleep
// D6=0 (grounded) Node-RED invokes DeepSleep
//
// D7 connects to the base of a BJT
// which in turn connects to the gate of a P-channel MOSFET to power the AUX devices
//    Logic '0' turns BJT 'off'
//    Logic '1' turns BJT 'on'
