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. […]
The resolvent of clock synchronization over internet. by PKJ, The web−based clock management system allows you to monitor clock status from wherever they are and centrally change settings. and this small device is built with PoE technology, thus IP clocks get their time, data and power from the same network that supports your other IP endpoints. […]
128X160 pixels in 18 bit color with a microSD breakout board courtesy of Adafruit Industries You can purchase the 18-bit color TFT LCD display with microSD card breakout kit (part# ST7735R) from Adafruit Industries This tutorial from Adafruit is for a 1.8″ diagonal TFT display & microSD breakout board. This breakout is the best way […]
Update (6/7/2012) – I’ve had to disable comments on this post, because it is being targeted by spam bots for some reason. Please use the contact page if you have a question about this topic. In this week’s arduino tutorial, we’ll be taking a look at SPI device control using the arduino. Specifically, we’re going […]
Many of you have probably seen the Awesome button done by Matt Richardson of Make Magazine. If not here is his video which was very well done and was the inspiration of my project. I liked the idea of having a button to press for a certain function on the computer, however i wasnt such […]
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 […]
Finally! It’s been about 3 months since my last Arduino tutorial – I’ve been keeping busy as usual. I’ve been working on this one for some time. I got the parts months ago, made an outline a few weeks ago, prototyped the circuits and wrote the code last week, and did the filming over the […]
The one wire Digital Temperature Sensor – DS18B20 from Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy. The most recent version of this library can be found at http://www.milesburton.com/?title=Dallas_Temperature_Control_Library We used version 3.6.0 […]
