Connecting multiple tact switches on a single input pin of a microcontroller

Connecting multiple tact switches on a single input pin of a microcontroller

Normally one tact switch requires one digital input pin of a microcontroller. Some designs implement keypad style multiplexing to get multiple switches on fewer inputs. However, there exist other techniques that allow you to connect many switches on a single input pin of a microcontroller. This tutorial demonstrates one such technique as applied to PIC12F683 …
