Arduino 4x4x4 LED Cube

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 did in order to build the cube and create some designs of your own. Step 1: Bill of Materials Bill of Mat ...

Color Changing Night Light with ATtiny using Arduino

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. Its brains is a ATtiny85, but you could also use an Arduino.  We have little boys that would appreciate this on at night. Step 1: Pa ...

LED Dot Matrix Display using an Arduino

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 display works and introduce the concept of multiplexing because this is an invaluable skill to have. Step 1: Things Required for t ...

Simple Relay Shield for Arduino

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 file. All the digital input are protected by a diode, the analog input are protected by a zener dio ...

Squirt – Arduino, motion activated water cannon

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 firing time within a limited area. The sometimes fickle readings from the PIR sensor just adds t ...

Arduino Pedometer

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 and winding road” but here’s t ...

Arduino Mega Pinout Diagram

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 button. It contains everything needed to support the microcontroller; simply connect ...

Traffic Lights Beginner Arduino Project

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 you will need. - Arduino - Solder-less Breadboard - 10 LEDs --- 2 Red --- 2 Yellow --- 2 Green --- 2 Smal ...

Arduino + Temperature + Humidity

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 product daily dump with which anyone can convert kitchen waste into compost at h ...

Marble Disorder – a marble maze simulator with tilt switches using Arduino

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 - watch that Bonus game: The Marble Disorder box is compatible with Ariad ...

Turing Alarm for Arduino

NOTE: This Instructable is currently incomplete. I will finish it before September 19.  I started this project after seeing Nick Johnson's Turing Alarm clock. I found that the PIC chip he used was a little too advanced for me, so I decided to use the Arduino microcontroller. The original project by Nick Johnson can be found on his blog here . All credits for the idea goes to Nick. The turing alarm forces yo ...

Arduino Electronic Dice using random numbers

This instructable will show you how to make an electronic dice with minimal experience using 7 LEDs, resistors, jumper wires, and of course the arduino (or arduino clone). I wrote this instructable for anyone to easily follow along and learn more about the arduino. Questions are welcome and will be answered as soon as possible. For less experienced users the code for the arduino is in "longhand" and several ...
