MEOWSER Architecture diagram of electronics
The database driven computer software sends commands to the Arduino which sends the on/off signals to all the LED lights. Shift Register integrated circuits translate one byte into 8 bits controlling 8 lights. Darlington transistor array integrated circuits are the high power power on/off switches for the lights which are switched by the low power Arduino.
