Waveform generators (also called function generators) are useful for testing and debugging circuits. I often use them to test the frequency response of electronics components like op amp and sensors. This waveform generator is powered by an Arduino. It outputs four waveshapes: sine, triangle, pulse, and saw, each waveshape ranges in frequency from 1Hz-50kHz. The […]

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 […]
Sous-vide Arduino Shield
*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC Sous-vide (/suËËviËd/; 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 […]
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 […]
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 […]
Localizer with SIM908 module using Arduino
The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver. […]
GSM GPS shield for Arduino Board
Shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. HARDWARE INNOVATIONS This new version (old Arduino GSM shield) has several new hardware features, that allow maximum customization and provide many configurations. We begin with the supply circuit […]
Easy Bluetooth Enabled Door Lock With Arduino + Android
Thanks to everyone who supported this project and voted for it in the Arduino Challenge! I was awarded second prize and hope to participate in more Arduino contests in the near future. This tutorial will explain a simple way to make a password protected bluetooth door lock using your Arduino, which can be unlocked by […]
Beginners guide to building Arduino robots with Bluetooth and Android
In this tutorial we are going to go over building a Arduino robot that can be controlled via bluetooth with an Android phone/tablet. This is a beginners guide that is going to briefly go over the process of wiring and programming your robot. Build list… The following is the list of components we are going to use: 1. Pololu […]
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 […]
