Arduino Leonardo AVR Development Board is a microcontroller board based on the Atmel ATmega32u4. It offers 20 digital IOs (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Arduino Leonardo differs

Introduction This is my second article relating to the Arduino Microprocessor Platform. The first one was a simple implementation of the SIMON game using the Arduino. The article can be found here. For an introduction to the Arduino Hardware, see jeffb42‘s excellent articles, as there is no point in repeating things here. What Is This

Max’s Arduino Mega and chipKIT Max32 both require 9V external supplies, but he really wishes to power them from a single 5V supply. Well, nothing is simple, is it? I ran into a minor “gotcha” with regard to my Bodacious Acoustic Diagnostic Astoundingly Superior Spectromatic (BADASS) display project. As you may recall from my previous

I’ve been reading a lot about receivers, and it sounds like one important thing is filtering. It makes sense too – simple receivers can suffer from front end overload due to a strong signal. And when on the ham bands, you never know where that strong signal may be – it could be someone driving

In this post I’d like to describe you a project I’m working on that consists of connecting an Android development board to one (or more) Arduino slave(s) using modbus protocol and rs485. Even though the idea of this project could be applied in many fields, I chose to contextualize it in a typical smart home

This video shows the Traffic light and pedestrian crossing I’ve implemented with an Arduino. It’s a reproduction of the crossing near my home, timings taken from a video of it. Incidentally, I produced the diagrams for this using a product called Fritzing. It’s a nifty piece of software that allows you to draw a breadboarded version of

Schematic Diagram You may remember, if you studied electronics as part of your science course at school, that there is a specific way of drawing circuit diagrams. Each component has a particular symbol (which may vary slightly depending where in the world you live) that allows anyone to look at the drawing and build the

The Arduino is a pocket-sized computer (also called a “microcontroller“) that you can program and use to control circuits. It interacts with the outside word through sensors, leds, motors, speakers… even the internet; this makes it a flexible platform for lots of creative projects. Some popular uses include: – programmable light displays that respond to

The EyeWriter is a low-cost eye-tracking apparatus + custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic Lateral Sclerosis to draw using only their eyes. The original design, as shown here, featured a pair of glasses as the basis for the eyewriter design: Since that first video, we’ve been hacking on

The PS2 mouse is an input device which can communicate with a host device using the PS2 protocol. It can be connected to a host device using the 6 pin mini DIN connector. The mouse will continuously give output which can be decoded to get the movement in the X-Y plane and also the status
