The code is for directly controlling the LED matrix (I had made a 10X8 matrix) through Arduino Uno. Here, I have used multiplexing which makes the task a bit difficult to understand at first. But once ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

All projects use an Uno R3 Arduino micro-controller board and various other components to teach circuitry, programming, and problem solving.

The build relies on an Arduino Uno as the brains. It’s equipped with an L293D motor driver shield to run two DC gear motors which drive the walking assemblies.

The Arduino software environment, including the IDE, libraries, and general approach, are geared toward education. It’s meant as a way to introduce embedded development to newbies. This is a … ...
