Welcome to my version of the LED reactive table! I was inspired by previous work using discrete LEDs, such as this one, but I figured it would be easier and more fun to use NeoPixels — programmable RGB LEDs that can be set to any color you want. The table consists of a large array of infrared emitters

I’ve always wanted to do an Arduino project, but never had any great ideas for one until my family was invited to a fancy hat party. With two weeks lead time, I was curious if I could both plan and execute a motion sensitive LED animation hat. Turns out I could! I probably went a

Arduino: Nokia LCD & Sensors PROBLEM: Making my Arduino, a Temperature-Relative Humidity sensor and a Nokia3310LCD screen work together. Now, I’m a Lazy Old Geek, so what I wanted was an Arduino kit that would take shields. This Freeduino was the cheapest that I could find at the time. http://www.seeedstudio.com/depot/freeduino-usb-complete-kit-p-58.html?cPath=79_82 Since I was at Seeedstudio,

This Instructable explains how to use a gas sensor with your Arduino. This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds. My cost to make this actual device was under $100, including the

Are you constantly being scared when people sneak up behind your back? Do you have bad hearing and can’t hear people approaching you? Do you want to just build a super fun Arduino project? If you answered yes to any of those questions, then this project is for you! I have a workbench in my

This time I’ll show how I used an Arduino to control a relay module with eight channels. Arduino in offers several advantages such as: – Open source; – Easy programming; – You can assemble your own board; – Is supported on various forums on the Internet; – Has several “shields” (facilitates the use of it

Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and

This example demonstrates one techinque for calibrating sensor input. The Arduino takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the

Experience Level: Intermediate (requires soldering) Time Required: 3-5 hours depending on experience J-BOT Kit Jameco P/N 2140285 Someone mentioned that Jameco needed a robotic mascot. I have always been a tinkerer, especially with radio-controlled electronics and so I volunteered for the chance to design and create the J-Bot. While this was my first autonomous
