ADC Interfacing of AVR (ATmega32)

The Analogue to Digital Converter of the Atmel AVR Microcontroller was one of the main reasons of me choosing it over the cheap AT89S52 microcontroller.

As mentioned in my previous blog post, I had recently given a workshop at the AIUB along with my friend Omee. Due to time shortage, I could not finish my presentation on ADCs. I wanted to share some of the materials that I studied here in my blog post.

Interfacing 7 segment displays with AVR (ATmega32)

Recently, I had the opportunity to give a workshop on AVR microcontroller in American International University of Bangladesh (AIUB). I had prepared some codes for the conference, which I will share here.

7 Segment displays can be readily interfaced to the AVR by applying high or low output to their pins from an AVR. For my circuit I had used a common anode 7 seg display.
