Pinout: g/y/r are on pins 2/3/4. Brown is on 5V, blue on gnd. External power on gnd & vin.
Running as /root/tl.pl on "squeezebox-klusbunker" (10.42.66.3). Sends messages to /dev/nr24l01p
current
Listens on nrf24l01, same channel as rest of infra. Command: STPLxxx where x is either '0' or '1' (ascii characters, not binary values).
old
Connected to jukebox.
Device: /dev/tl
Serial, 115k2, requires ascii-string ended with cr/lf/cr+lf/lf+rc/and other variations. 3 characters (not binary bytes) that are either 0 or 1. Order: green, yellow, red.
Arduino requires extra seperate power supply or else it'll go in a reboot-loop when switching.
