Reseting
V1
Some time the V1 hardware on the Airlock door needs resting by hand
The main board is located to the left of the Cash Acceptors in the Members storage area
Cycle the power first by toggling the switch indicated by the purple arrow, then reset the Arduino (Red arrow)
V2
Open the grey box and hit the reset switch
