LED Matrix with Game Controller using an Arduino

This project was built for my introductory electronics class at the University of Waterloo in Canada.  This was my first introduction to electronics and therefore, my first project. Follow these steps to build a 16 x 16 LED array with a wall (different colored LED on the border), powered by an Arduino Mega 2560.  I have also included the construction details of a game controller. This project is ideal for a ...

Sous-vide Arduino Shield

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC Sous-vide (/suːˈviːd/; French for "under vacuum")[1] is a method of cooking food sealed in airtight plastic bags in a water bath for a long time—72 hours in some cases—at an accurately determined temperature much lower than normally used for cooking, typically around 60 °C (140 °F). The intention is to cook the item evenly, not ...

Audio Output using an Arduino

Generate sound or output analog voltages with an Arduino.  This Instructable will show you how to set up a really basic digital to analog converter so you can start generating analog waves of all shapes and sizes from a few digital pins on an Arduino.  (This article is a companion to another Instructable I've written about sending audio into an Arduino, find that here) Some ideas that come to mind: sample b ...

Audio Input using an Arduino Board

Send sound into your Arduino.  This Instructable will show you how to prepare audio so that it can be sampled and processed by an Arduino to make sound responsive projects and audio effects.  (This article is a companion to another Instructable I've written about building an audio output circuit for an Arduino, find that here) Some ideas that come to mind include: beat detection- trigger lighting effects, b ...

DIY Arduino Motor Shield

Today, I'm going to show you how to make an Arduino motor shield (driver) at a low cost. It works splendidly, its posses almost all the characteristics of the original Arduino motor shield. It's almost considered as a clone. The original Arduino motor shield has the same motor driver chip (L298), the only difference with it, is the package type, my project contains the vertical version of the chip L298 (wit ...

Arduino Board Step Sequencer

I was wondering about on making a sequencer, a big 16 step sequencer was what I wanted to make. To it's full extension with lots of features including single leds for each step, midi input and output, etc. Then I realised that I should start from a more basic model and then maybe tweak around to see what I can do. So while surfing the web and between other small sequencer projects I found this arduino seque ...

LINUSBot – Line Follower Robot using Arduino

The operation of this Robot is quite simple. Infra-red sensors placed at the front of the chassis  will monitor when our Robot is over a black line or when it is over a white background. In this project we will use the appropriate rounded chassis to the Robot. In case the robot being on the black line, it will always go ahead, and in the case of out of line and fall into a white area, it will determine whet ...
