Old style keypad from days gone bye. It's a revamp of an old circuit of mine that now retains the last number pressed. Again note to all new comers to Everycircuit. If you click “in Chrome” or tap “in app” on a user names you will see their profile and a list of their public circuits for viewing.

ADC voltage more than 5 is not recommended. It is running on "Every Circuit" but not run on PCB.
