## 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.
