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 […]
A quick demo video for your pleasure. This is an instructable for a target practice system for airsoft and nerf weapons. The system has been designed to test a shooter’s reaction times and accuracy. Sam and I have been meaning to do this project for a while, and when the microcontroller competition opened, coinciding nicely with […]
UPDATES Feb 20, 2013: In response to a question by student Hala Abuhasna if you wish to use the .NET Serial class, use the naming convention “\\\\.\\COMn” and replace n with a number > 9 to define your com port for COM ports above 9 such as COM10, COM11, etc. Mar 23, 2012: Featured on […]
Arduino Leonardo Introduction: Arduino Leonardo is a microcontroller board that uses ATmega32u4 (datasheet) as the main chip. Most of these include twenty digital I/O pins out of which seven can be used as PWM outputs and twelve can be used as analog inputs, sixteen mega Hertz crystal oscillators, micro USB connection, power jack interfaces, ICSP […]
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 […]
