UPDATE FEB 2012: This guide is featured on Adafruit’s blog http://www.adafruit.com/blog/2012/02/14/arduino-based-line-follower-robot/ This is Faz3a II, my first line-following robot, which I also hope to use for maze-solving. I used the Arduino Uno, Adafruit motor shield, Pololu’s QTR-8RC line sensors and motors. You can build a cheaper and lighter version of this robot using the Atmel

Read Inputs

Using The PCF8575 i2c i/o Expander To Read Inputs With Arduino

Sensor – Transducer – Detector Projects / By

This Instructable will show you just how easy it is to add extra inputs to your Arduino. You can use this technique to add hundreds of extra inputs to your Arduino with only two wires by using a fancy communication protocol called i2c (eye-squared-see). What I have used… PCF8575 SMD to DIP breakout board Teensy-Arduino (any Arduino

Laser Pointer

Control Fluorescent Lights with a Laser Pointer and an Arduino

Sensor – Transducer – Detector Projects / By

A few members of the Alpha One Labs Hackerspace do not like the harsh light given out by fluorescent fixtures.  They wanted a way to be able to easily control the individual fixtures, perhaps with a laser pointer? I got right on it.  I dug out a pile of solid state relays and brought them to the

Introduction We aim to introduce young students to engineering and teach them about solar energy; by having them build a Helios as part of their curriculum. There is an effort in engineering to push energy generation away from the use of fossil fuels and towards greener alternatives. One option for greener energy is to use

Sensor – Transducer – Detector Projects / By

The Internet of Things has brought a lot of formerly complex device applications into the homes of many craft brewers and wine makers. Applications with level sensors have been used for decades in large refineries, water treatment plants, and chemical plants. With sensor prices falling, now both industrial and DIY can monitor the volume of
