Arduino Piano

While I was free during my holiday, I decided to make a simple Arduino Piano playing musical notes. Playing musical notes is quite simple with the Arduino built in function Tone(). Overall this project’s difficulty should be easy. Another reason I wanted to make this mini project, is to make a piano with 12 keys, but using lesser amount of pins.

Development of 48×8 Led Matrix Display

I was always fascinated with LED Matrix Display because it makes a good and clear display. I always saw LED display used as advertisement signboard. It can be programmed with variety of animations. So I decided to make myself a 48×8 LED Matrix Display. Of course, I start off with a smaller one by soldering LEDs on stripboard, making a 8×8 LED Matrix. I tried to understand how the LED Matrix works and how to deal with the programming part.  Continue reading “Development of 48×8 Led Matrix Display”

Build your own Arduino Uno

I often use Arduino to test out my project prototype before complete it. Sometimes, I wanted to test more than one project at the same time. I would need more Arduino, but the original Arduino is over my budget for prototyping purpose. Therefore, I decided to make my own Arduino. Some of the benefits of making your Arduino (at least for me) are it is cheap, easy, learn to design PCB and electronics at the same time. Although there are a lot of guides on how to make your own Arduino, I decided to make one so as I can share with my readers, and at the same time document it for myself.
