Picked up an Arduino Mega and an 8 relay board and was thinking it would be cool to use it to make a custom theme hybrid pin.
The Mega has 54 I/O pins and I was thinking that a 74LS154 would decode 16 outputs to drive 16 relays for pop bumpers, slingshots, and many other powered objects on the playfield. The trick would be to get the signal long enough on the relay so it can power the solenoids long enough for them to do their jobs. These could also be used to run EM scoring assemblies.
A smaller Arduino Micro and a 4 relay board could be used to drive the chime boxes separately and communicate over serial with the Mega.
That would leave plenty of inputs to connect to switches on the playfield.
Am I crazy?
