This project came to my mind when doing my MEM (Mechanical Engineering Measurement) project, a subject in my B.tech. The idea is to measure the angular velocity of my bicycle’s wheel. Thus knowing the diameter and the all time mathematical legend the pi(3.14) the speed can be …
I saw the Open Hardware Pulse Sensor at thought I’d try to make it at home. Took me awhile, but here’s my bumbling process. Step 1: Pulse Sensor — Overview I’ve been working on re-making the the Open Hardware Pulse Sensor so it’d be “easy” to send off to OSHPark and make at home. I’m not sure but I …
I wanted to create something for my wife as a present and this is what I came up with. This is a dark activated color changing night light. It has a sensor that can tell when the room light is turned off. This then will light a RGB LED and slowly fade through different colors. …

This Instructable details how to build a holiday dreidel display for your roof. It uses coat hanger wire, rope light, and an Arduino controller to control a fading demo mode and a “spin” mode. In the demo mode, the symbols fade in and out, going from one to another. In “spin” mode, the symbols flash …

This is a beginners project for the Arduino. I am using the Arduino Uno but should work with little or no modification on other arduino models. Setting up the hardware is very easy. This project is more of a training tool for learning how to program a timer list while listening for a button press. Parts …

Overview: This instructable will cover the building process of an 4x4x4 LED Cube. I will be using an Arduino to control the LEDs. Since the Arduino (Freeduino) has a total of 20 pins (including the analog pins) we will not need to have any multiplexing or shift registers. I will take you though what i …
To explain my 4x4x4 interactive LED-cube published before, a bit more clear, I will try to make my first step by step instructable. This 4x4x4 cube is interactive by using the top four corner LEDs both as LEDs and as sensors that will react on light. Depending on what LED gets the least light, the …
**DISCLAIMER** I do not and will not take responsibility for anyone who gets in trouble for this, by either imitating emergency personnel, or using without a permit/lisence. Updates! -I have shortened the code -Changed 16 LED’s to 8 -Changed/added more flash patterns -Renamed variables As promised, this is the ATMega 2650 version of the police …
I made this project on the same night that my Arduino Duemilanove arrived from Cool Components. After being an Instructables member for about a year I though it was time I should contribute. There is another Arduino traffic light project similar to this, but it is much more complex; mine is aimed at beginners and …
