Connecting multiple tact switches on a single input pin of a microcontroller1

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 […]

Expanding the number of I O lines using Microchip MCP23008

Expanding the number of I/O lines using Microchip MCP23008 using pic microcontoller

A microcontroller comes with a limited number of general purpose input and output (GPIO) ports. However, some applications may require more ports than are available on the microcontroller. In such a case, GPIO expanders can be used to increase the I/O capability of the microcontroller. MCP23008 is one such device (manufactured by Microchip Technology) which
