It has been all dry theory in the Brushless DC (BLDC) motor with Arduino series up to this point. This is where it gets to be more fun. If you’ve just arrived, please check out the previous two installments: Driving a three-phase brushless DC motor with Arduino – Part 1. Theory Brushless DC (BLDC) motor

RepRap Arduino Mega Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder

Well, It had to happen. I first published my WordClock project in September 2009. It was a Microchip PIC based clock, using a PIC16F877A microprocessor. In the last year and a half, I have been constantly improving it, and have adapted it to the Arduino, and even designed an updated controller board for it. Well,

I recently needed to measure how different materials affect light transmission for a gardening project. I decided this was the perfect opportunity to try out the new logic level converter to run both a 5v LCD and a 3.3v light sensor on a single i2c bus. I used the following parts in this project: Arduino

Update! See Step 32 to find out how to use this project with a green laser! Also – checkout the LaserTweet Instructable to make this project display data from Twitter: http://www.instructables.com/id/LaserTweet-Twitter-Projecting-Laser-Show/ This project uses an Arduino and some cheap audio speakers to create a real laser show with full X and Y axis control. The

The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of (low) radiation like soil, rocks (an article about my trip with Geiger–Müller counter on Śnieżka mountain). Principle of

I had a Holux M-1000B Bluetooth GPS module that was just gathering dust in my room. I had bought it from DealExtreme back in the days when I had GPS-less (but external GPS capable) Nokia E51. Upgrading to a Nokia E52 has since made this receiver redundant. However, since getting an Arduino, and being put

I wanted to learn how to interface with I²C devices using my Arduino, so I bought a DS1307 clock and crystal kit from Earthshine Electronics. I’ve no association to them, but I’d recommend having a look at their shop. Their prices are very reasonable, unlike most Arduino component retailers. I²C is an addressable serial interface.

Lampduino is a computer-controlled free-standing floor lamp, comprised of an 8×8 RGB LED matrix. The lamp stands 45″ high and 18″ wide. Light emanates from both sides. It has various display modes, as well as an included editor for creating animations. The lamp is controlled via an application running on a PC host. The display

My second holiday project was a bit more fun than just blinking lights. I decided to tear apart a $10 RC jeep and control it with the Arduino. For this project, I added a motor shield on top of the Arduino that I purchased at the same Radio Shack where I found the RC car
