I am going to show you how you can use an RGB LED and a Cds photocell as a colour sensor for a micro-controller. I will illustrate the method to retrieve a colour using Arduino, and I will show you a how you can verify the colour being scanned with a small Processing sketch.We will be […]

Well I managed to kill my Arduino. It no longer accepted uploads with the classic out of sync error. After asking on the Arduino forum I was told I would need a high voltage programmer to rectify, so I decided just to buy a new chip. I was a bit scared about doing this but

Research Group: Ryan Mountcastle, Minh Trang Nguyen, Nathan Ranno, and Ryan Ward Launch: Whitworth Fall 2012 This experiment was designed to examine cosmic ray activity in the Earth’s atmosphere as altitude increases. The previous group’s project utilized three Geiger counters stacked vertically to eliminate false positives. This only accounts for rays travelling in the vertical
f you’ve ever wanted the ability to use some form of hardware-based authentication in your projects then this is the board to do it with. The Parallax RFID (Radio Frequency Identification) reader is super easy to configure. It only takes four wires! It uses serial protocol to transfer information from RFID cards to the Arduino.

Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even

You are building a soil temperature sensor. We need a waterproof thermometer that we can burry in the soil. The sensor is made up of a small circuit enclosed in a piece of heat shrink (to waterproof it). Supplies: (see the parts page) an LM335 temperature sensor a 33K and a 56K resistor a short
