Infrared (IR) sensors are normally used to measure distances, but they can also be used to detect objects. By connecting a couple of IR sensors to an Arduino, you can make an intruder alarm. Overview Infrared (IR) sensors are normally used to estimate the distance of an object, but you can also use them to detect the …

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 Lab. I bought an …

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 will …

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 …

This was a fun project. Push the red button, watch the dice ” ROLL ” then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone board. Powered by 4 AA NiMD batteries. Can you find the SECRET SWITCH in the main picture? Where is the SECRET SWITCH? …

Hi guys! So for my electronics class this year we were tasked with creating some kind of electronic gadget in order to demonstrate what we learned over the semester. Being a car-loving type of guy, I decided to get a cheap RC car and see in what ways I could hack it using an Arduino …
If you touch the package, it will scream and run away–changing its course when it strikes an obstacle. When you lift the gift tag, light strikes a photocell and operation commences. Motors and a sound module are controlled by an Arduino (and Arduino Motor Shield). Major components required are: Motorized toy–Kid Galazy Morphibians Rover Remote …
DIY Arduino based lockers can be found plenty in the internet where keypad was used to feed lock input. But this Bluetooth enabled Door locker uses Bluetooth as a medium to connect with the locker and your smart phone to feed input credentials. This locker allows you to lock/unlock your locker without physical touch when …
Use a Classic Nintendo controller to lock and unlock your door! The output from the Controller is read by an arduino and it looks for a particular combination of buttons, once the combination is entered it sends a signal to eject a Cd-Rom Drive which pushes or pulls the lock. I started making this project …
