Hey everyone! 👋
Just for fun, I decided to take on a small electronics project: building my own Arduino-compatible board from scratch, based on the Atmel ATmega328 microcontroller.
Why build one instead of simply using a ready-made Arduino? For me, part of the fun is understanding what’s actually happening under the hood and seeing how a few basic components can come together to create a fully functional microcontroller board.
Here’s what I have for the build:
- ATmega328 microcontroller
- Crystal oscillator
- Resistors and capacitors
- Voltage regulator
- LEDs
- Breadboard and jumper wires
- A few other components needed to get everything running
The only thing missing right now is a battery, which I’ll pick up tomorrow. 🔋
Once assembled, this little custom Arduino could be used as the foundation for all kinds of projects – sensors, automation, IoT experiments, robotics, or simply more electronics tinkering.
For now, the goal is simple: build it, power it up, and see if it works! 😄
Nothing fancy, just a fun little project and a good excuse to spend some time with electronics.
See you soon!



This project refers to an Arduino sketch which is used to produce animations with more than one LED. You can place several LEDs in a row or in any order you wish and enjoy the flow of traffic. Furthermore, if you wish to change the animation you can choose the next in line by pressing a special button. One such application might remind you of the Christmas lights.
