This 3X3X3 ft. LED PVC cube is the ultimate in mood light fun! An LED (light emitting diode) will burn longer than traditional bulbs so that you can enjoy your giant light for a LONG LONG time. Build it and see! Step 1: WARNING!!! THIS PROJECT WILL COST ABOUT $150 Also…. make sure that your dimensions

No longer will you have to pay hundreds of dollars for a heart rate monitor! The Smart Heart Monitor will be able to do all of your cardiac measuring needs for you! The Smart Heart Monitor measures the user’s heartbeat using an LED and a very sensitive photo-resistor attached to the user’s ear. A light

As a result of the questions from lekirst on this ible of my hand: LED-as-lightsensor-on-the-arduino/ and the cleaner code made by hansc44 at: Arduino-Use-LED-as-a-light-sensor/ it was time to come with a better Ible. So here it is. (I didn’t solve lekirst’s problems yet so she probably is open for suggestions) What is the idea? You might know that a LED emits light

With this you just type the text you want on your computer and your 5×5 dot matrix shows the message. Used: ~25 leds ~Arduino uno ~5x 100ohm resistor ~and a bit of skripting It took me a while to figure this all out but in the end it was quite rewarding. not really practical though.

This is my instructable on charlieplexing a LED row/string with the arduino. I noticed that there weren’t many instructables on charlieplexing using an arduino, so i made this. I tried to keep the project simple, but that didn’t work very well. The soldering is complex, I wouldn’t recommend this as a first time soldering project.

The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a

A Nixie Tube is a Neon gas-filled tube, that has a wiremesh anode with various cathodes shaped like numbers or symbols. Back in the 1950s they were used in computers, calculators, and laboratory equipment. Nixie tubes were replaced by LEDs and VFDs(vacuum fluorescent displays)in the 1970s. They were too costly to to mass produce so
