Gate

You are standing at Noisebridge's locked front gate through the fence around the Patio to the east. You see a red doorbell buzzer button, an RFID Token reader and Payphone keypad. EXITS: To the west is the parking spaces and to the south is the Street. >

Noisebridge's front gate is in our parking lot on the street at 272 Capp St. and leads to the Yard with the regular door and roll-up garage door behind it.

It uses the Payphone as a keypad and has an RFID Token reader for 24 hour access card holders such as philanthropists and members.

Payphone Keypad

This is some ethernet cable split and used as low-voltage signal wires.

The current wiring of the gate phone keypad, to the brains in the grey box behind, is:

Wire mapping

From cable bundle	To phone component
Gray wire	row 1, pin D0
Green wire	row 2, D1
Brown wire	row 3, D2
Red wire	row 4, D3
Orange wire	column 1, D4
Blue wire	column 2, D5
Blue + Black dot wire	column 3, D6

Added to this, the red LED and front buzzer share a signal wire pair. Green and yellow are used for these. The wp:LED has bias, a correct direction. The buzzer, phone earpiece, is driven directly by the arduino, using a tone generation library.

The last 2 white wires are reserved for future use supporting voice from the phone.
