Quad 7-Segment Display Interfacing with ATmega16

4136

The Quad 7-segment display is a four multiplexed 7-segment based interface board from ABLab Solutions. The four 7-segment displays are connected with each other using multiplexing technology.

In this project, we will learn How to interface a common cathode based Quad 7-Segment display with AVR ATmega16 microcontroller. Here, the ATmega16 microcontroller will do the decimal to 7-segment decoding for common anode 7-segment display and it will display the numbers from 0 to 9 and then dot (.) in all the four common cathode 7-segment displays of Quad 7-Segment display with a time delay of 500 millisecond between each number. After displaying dot (.), the microcontroller will repeat the above process continuously.
