Multiple switches using a single PIC input
There are many techniques for connecting multiple switches to a PIC microcontroller. One technique requires only one ADC pin to detect voltage levels, with each switch corresponding to a voltage when pressed. For example, if we need to connect 16 switches using a 10-bit PIC.
