Relays control

The relays boards must first have the following connections:

  • GND (relays board) => GND (raspberry PI card)
  • VCC (relays board) => 5V (raspberry PI card)
  • Each INx on the relays board must be mapped to a GPIO pin of the Raspberry Pi

Use GPIO.output(num, True) to stop a relay and GPIO.output(num, False) to start it again.
