Issues trying to read rotary dial on Arduino with debounce IC
Post Body
I'm working on a personal project to turn a rotary phone into a message bank. User would lift the phone from hooks and an LED would turn on, dial a number, and play a message depending on the number dialed. Running on an Arduino Pro Micro (5V, 16Mhz), using an MC14490 Bounce Eliminator for the dial and hooks, and DFPlayerMini to play audio. The hooks and DFPlayer work as expected but I get no signal from the dial. Dial YEL and Dial WH are where the pulses come from. Any ideas on what the issue could be?
