Intervawhat? An intervalometer is a camera controller that signals the camera to take a picture after some set interval. This is really useful for creating time-lapse videos. For a long time, I used my TI-89 calculator to create time-lapse videos with my Canon digital Rebel XTi. It worked quite well, and the calculator in/out port just happened

The WiFi Shield was delivered by Amazon. The Arduino UNO Rev 3 was found at RadioShack… First you need to load the last Arduino IDE (Ver 1.0.2) it has the necessary library to use the WiFi shield. Tried the examples “Scan for available networks” and “WPA network example” from: http://arduino.cc/en/Guide/ArduinoWiFiShield It works like a charm!

Today we are going to examine the Maxim MAX7219 LED display driver IC. The reason for doing so is to show you how something that used to be quite complex can be made very simple – and that is what all this technology is for, isn’t it? If you have ever tried to control lots

Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible. I built this as a table top or wall mount model, but it can be scaled up to make a coffee table. I built it as a study for a more ambitious project, which

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

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

A computer is a very handy thing to use in your robots. If you start listing all the features that can be used for robotic purposes you’ll find that it is cheaper to buy a netbook than buying LCD, wifi and bluetooth modules, cameras, speech synthesizer modules, keypads, memory card readers, speakers and many other stuff.

Use the Maxim MAX7219 LED display driver with Arduino in Chapter 56 of our Arduino Tutorials. The first chapter is here, the complete series is detailed here. Update – 4/1/15 – This article is pending a re-write, please refrain from comments and questions until the new version is published. Introduction Sooner or later Arduino enthusiasts and beginners alike will come

After buying a Nanode (an Arduino-compatible board with ethernet built-in) last weekend, we’ve been trying to work it out by making a couple of simple examples, the ‘Binary Dice’ is the first one with input and outputs. A note, this code example is based on the one from the book Arduino: A Quick-Start Guide by
