Building a Robotic Platform

I started this project a while ago. My intention was to adapt a toy remote controlled vehicle into a generic […]

I was looking for some parts a couple of weeks ago and came across an old TV flyback transfomer, so […]

After I wrote this guide on how to build an ultrasonic range sensor from scratch, I have received many comments […]

I am in the process of converting a remote controlled toy vehicle to an autonomous robotic platform. My initial thought […]

I needed some ultrasonic range finders for my project. But most of the commercial sensors like Parallax’s PING sensor and […]

It is fairly simple to build a digital metronome using an ATmega328 AVR chip and some minimal programming using the […]

In my previous post, I showed a simple optical encoder circuit that is TTL compatible. The main drawback of the […]

To detect wheel rotations in model vehicles, we would need to install some kind of sensors on the wheels to […]

Modified sine wave is essentially just a pulse width modified square wave. It is a very useful waveform for power […]

I recently bought a TrendNet TK-207K KVM switch. After hooking up my mouse and keyboard, I was suprised to find […]

Continue with my previous article, let me first explain the code a little bit.

A signal generator can come in handy when working with digital and analog circuits. While most commercial grade signal generators […]

I just bought a Brother MFC-7340 multifunction laser printer to replace my old Lexmark Optra E310 which I have had […]

I built a rather generic I2C data logger a few weeks back. As I mentioned in my earlier posts, it […]

When working with micro-controller projects, it is often necessary to perform calculations in binary and hexadecimal forms. While almost all […]
