I am working on a Project with PIC16F676. I need several input buttons but I am falling short of input pins. I have one plan.
**broken link removed**
I think I should be able to use the PIC's ADC channel to read several buttons by utilizing only 1 pin. Do you think this is plausible? What are the troubles I may run into doing this?
Is this a general practice or I am trying to do something out of the box?
Also, can you think of better options?
