Overview The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the …
My partner and I wanted to make heart rate monitor that does more than simply measure a user’s heart rate. Our heart rate monitor talks! Each button gives a verbal description of its functionality and makes the measurements visible on the screen. This monitor will save the last four readings, display them, average them, and …
I have an Arduino Uno connected to two IR transmitters and respective receivers. Basically, when one of the receivers detects a beam break, I have a strand of LEDs display a pattern. This all works in principle, but the problem is that when the IR transmitters and receivers are connected to the Arduino, the LEDs …

When I was a kid we went to the drive-in theater to see movies like The Legend of Boggy Creek and Evel Knievel. I loved those movies but I remember just as vividly those retro-cool metal speakers that entered into our car for these campy films. A few years ago I found one of these speakers at a …

I like cheap electronics for playing. Cheap is good for budget conscious hobbyists and China is delivering lots of toys for playing – one being the inexpensive “mono” OLED displays. The single-color displays often come in a dual-color implementation where the top row of pixels are one color and the remaining majority of the lower …
Chachka is born! Chachka is an Adafruit Trinket CLONE built from the ATtiny85 microcontroller. Because it is a current Adafruit product, it has a training guide and its own support forum and lots of sample code. All of this means that like an Uno clone, the Chachka will be well supported with firmware and libraries and …

mo.momi Led strips are amazing! Firewalker-led-sneakers(http://learn.adafruit.com/firewalker-led-sneakers) by Adafruit inspired me. I wanna change a way to control it, instead of “pressure-sensitive”, I use a accelerometer sensor judging the motion of slipper. It’s simple, I complete this version only calculating the acceleration on “z” axis, weather i’m speed up or slow down. Led will “flow” if …

I think these RGB LED Matrix displays are one of best displays you can get for your Arduino projects, they are incredibly bright and vivid and are actually pretty easy to use too! They can be used for displaying text, images or a combination of both Check out some of the examples of what can …
I originally started this project because I wanted to recreate the scene in the movie the Close Encounters of the Third Kind where the humans are communicating with the Mothership via a huge color organ. So I glued various bits of software together and made some prototypes and before I knew it I was talking …
