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 […]

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. […]

In this project, you shall again use two sets of shift registers. These will be connected to the rows and columns of the dot matrix display. You will then show a simple object, or sprite, on the display and animate it. The main aim of this project is to show you how a dot matrix […]

Shield to control 6 relay, 6 digital input and 6 analog input with Arduino Duemilanove, Arduino UNO. The digital inputs and relay outputs are equipped with an LED that indicates the status. The circuit diagram is very simple: Step 1: Schematics and PCB In this step you can find the circuit diagram and the PCB […]

Squirt is a motion activated water cannon using Arduino. This was designed for use in the garden but as it’s winter we tested it in the bathroom. It works! True motion tracking is expensive and complicated so this system activates when the victim moves into range and randomises the position of the cannon and the […]

Problem: So my nutritionist (doesn’t everyone have a nutritionist) suggested I should increase my exercise which primarily consists of walking my dog. She even gave me a chart of activities and calories burned. Here’s an example. http://www.nutristrategy.com/caloriesburned.htm Well, being a LAZY OLD GEEK, I decided to monitor my walking electronically. Solution: It was a “long […]

Arduino Mega Introduction: The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset […]

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 […]

A simple temperature sensor using one LM35 Precision Temperature Sensor , Humidity Sensor and Arduino, so you can hookup on your future projects. The circuit will send serial information about the temperature and humidity so you can use on your computer. I have taken data from my compost. The project is related to an existing […]

Marble Disorder is a borderline case of Marble Madness 🙂 It simulates a marble maze by sensing the box’s orientation with 2 tilt switches. Stop the press: there’s a new and more intuitive version that doesn’t require the spin knob (See video). I keep documenting the original version below for historical purposes, but don’t watch this – […]
