Embedded projects I have developed in my spare time

I keep working on different projects to learn new embedded technology, software, and applications. Some of my personal work which I did in the past is shown here. I am sharing these so others can learn and get some inspiration.

Some of my embedded system projects which I did in my spare time are mentioned below:

1. Renesas (R8C2B Tiny) General Purpose PCB Board

2. Graphic LCD interface with Renesas MCU (R8C Tiny)

3. Interfacing SD/MMC Card with Renesas MCU

4. Programmable High Precision Electronics Load
