Arduino and Infrared … (Part 2)

In the first article of the series, I explained how to break the code of a standard infrared remote control. In this article, we will use these results to control real world devices. The so called “real world devices” are, at this point of the project, three LEDs. I’ll keep lamps and washing machines control for the...

Arduino and Infrared (IR) Remotes

This Article is the first of a series on programming an Arduino micro controller to control X-10 devices using an infrared (IR) remote control. This is a relatively cheap project. To make the first part of this project you will need an Arduino micro-controller, an IR receiver and any IR remote control. The overall cost should...

Kids Clock

Ok, that one is not rocket science but it realy realy worth the 20$ Arduino micro controller I used to make that kids clock. The idea here is to make sure my 4 years old kid will not wake up at 3:30AM because he has confused the small needle with big needle. The code is...

First Light

I took my first picture, during the holiday, using my new motorized scotch mount. The following is a 2 minutes shot of the cygnus constellation region centered on the North America nebulae. The brigth star near the nebulae is Deneb. Camera: Canon 20Da Lens: Canon EF 17-40mm 1:4 Ultrasonic Exposure: 2 minutes at ISO1600...

Arduino Timer Interrupt

I am actually working on a small project using an Arduino micro-controller ATMEGA 328. Timing issues are very critical so I had to find a way to use timer interrupts. I found the following code and adapted it to the ATMEGA 328. http://gonium.net/md/2006/12/27/i-will-think-before-i-code/ Following is my implementation for the ATMEGA 328 … The code...

Bluetooth is Watching You …

I thought it could be fun to write a small program in Python using Bluetooth. I then read an article about the explosion in popularity of Bluetooth devices and decided to write a small program that would detect Bluetooth devices in a specific location. A trace of all these devices would then be kept in...
