Building a Circuit on the Arduino Prototype Shield

Arduino Proto Circuit Banner

Hi. Sorry for the long absence, I’ve been very busy with internship for the past 1 week. I found some time to do a short demonstration on building a circuit on my home made Arduino Prototype Shield. If you’re interested in reading how I made the shield myself, here’s Part 1, Part 2 and Part 3. I’ve decided to show …

Home Made PCB – Etching Copper Layer (Part 2)

Pcb 2 Banner

This is Part 2 of my journey in making my first Home Made PCB. If you’ve not read Part 1, here it is. In the last post, I showed the entire process of etching the photo resist layer. Now what’s left of the photo resist layer (green in colour) is the actual PCB layout. Beneath the photo resist layer is …

Home Made PCB – Etching Photo Resist Layer (Part 1)

Pcb 1 Banner

I’ve always wanted to make my own Arduino Prototype Shield. This shield allows the user to use a breadboard on an Arduino. It’s a very simple shield but if I were to buy it, it will cost me at least RM30. An example would be this Prototype Shield from It is sold for USD 15, which translates to approximately …

There are many ways a microcontroller can display its’ output, but they can be categorized into three types, sight, motion and sound. Sight means that the output is visual based, such as LEDs and LCDs. I’ve done many examples on that so today I’m going to step into new territory, sound. To produce sound, we need a speaker. Normal speakers …
