“I decided to do this project for several reasons: first I like music, second I have a huge collection of MP3, and third I wanted to be able to play them anytime in my living room. I began the project with one major restriction, the printed circuit board of MP3 player MUST be single side in order to do it myself.”

“In this article, we’ll continue looking into how to control servo motors by controlling two at the same time. We’ll take a look at some of theory behind the actual servo signal and control, then how to wire up the two servos to an Arduino UNO board and finally write up some software to control them both synchronously and asynchronously.”

“In this tutorial, we will use the Arduino to read a flex sensor. The flex sensor is a device that changes its resistance proportional to its form, stretched or relaxed.”

“Project Holodeck is a virtual reality platform built with consumer facing technology, DIY off-the-shelf components, cutting-edge custom software, and creatively integrated peripherals. The goal of Project Holodeck is to bring 360-degree 6-DOF full-body virtual reality out of the research lab and into a fun, accessible consumer gaming platform.”

“Pure awesome! I have the best of friends who made this for me. 30 bright BLUE LEDS hot glued into straws, wired up to a driver circuit, then manually poked through the bottom of the cake! Man, it must’ve taken some planning and time to make this! The whole thing was powered by six 9-Volt batteries! All lead-free solder a plus.”

“We got two PCB’s with motors up and running. They contain one Attiny2313 as the brain and one L293 as motor driver. They are used to test the sensors and the programming. One is already equipped with a sensor shield include four 38kHz IR receiver for the navigation. The idea is to arrange these four receivers in a way that the robot does not have to make a 360° spin to find the IT beacon.”

“This device is no match for an Randy’s sensor, but it does (minimally) work. Think of this little project as a fun hack more than anything else. But with some tweaking and size reduction someone could probably implement an occasionally working altitude hold sensor for a fixed-wing RC aircraft.”

“In the spring of 2011 my friends and I decided to bring one of our childhood memories to life. In the opening scene of Back To The Future, Marty stops by Doc Brown’s lab to use his 8 foot tall guitar amplifer. Naturally, the speaker blows Marty across the room when he strums his guitar… Inspired by this scene, my friends and I decided to build a giant speaker of our own for the 2011 UW Engineering Expo.”

“The concept for this small birthday present was to create a small heart shape with red LEDs and then to draw a heart shape underneath it on the PCB as a backdrop. Then a microcontroller was added to control the LEDs for both fade and pattern control. Controlling LEDs via PWM allows us to save precious battery life and control the exact brightness of each specific LED.”

“This project is a simple Arduino clone and that is why the distribution of the pins does not match the standard Arduino. However, most of the Arduino features are included in this board. The circuit is protected by an automatic reset fuse of 500 mA to prevent any over current form the USB port.”
