The Arduino Ethernet Shield is a sweet toy!!! Everybody, from the beginner who got their Arduino yesterday and hasn’t slept since, to the hard core pro who learned c as a second language, can learn how to use the Ethernet Shield and have lots of fun with it. Its that awesome! As soon as I […]
Welcome ladies and gents! As an entrepreneur, I’m always looking for great projects to share. Myself and two other classmates recently put together a project for our Master’s of Engineering program in Technical Entrepreneurship, and we’re thrilled to share our vision with you. Remember that old Connect 4 game sitting in your basement/closet/chest/Batcave? You’ve always
This is a project I worked on for my electronics class at Pomona College. Thanks to Professor Dwight Whitaker and Tony Grigsby for their help and guidance throughout this project, and credit to Jonathan Wong for the idea for this project! Also, here’s a list of Instructables I looked at for ideas/inspiration while working on
Speech-controlled Game Boy Advance using arduino Continue Reading
First of all, this project is not finished. We’re still trying to improve and fix some problems. Right now, we’re only able to translate letters from “A” to “E”. The program still have problems while identificating those letters, the values for each of them match sometimes, so we’re still trying to fix this. Many people
Green wire is zero_cross signal, goes to Arduino digital pin 2 in. Yellow wire is light dimming signal, comes from Arduino digital pin 11. The LED on board should dim or fade along with the AC light source. Fading will not work until AC power is connected, it depends on the zero-cross info from the
How many TV shows and movies have some mysterious device counting down to zero those displays are 7 segment displays.With the 7 segment displays you can display any number or some alphabets that your heart desires. At first controlling a 7 segment display seems quite complex but it quickly becomes clear. What follows is a
What is a breathalyzer you may ask? It is a device for estimating blood alcohol content (BAC) from a breath sample. In simple terms it is a device to test weather a person is drunk or not. As the title suggests it runs on the Arduino. Our breathalyzer uses the MQ-3 alcohol sensor from sparkfun.
This is basic for your arduino projects, input switch read from digital input. When ever switch pressed, LED will turn on. Instruction; 1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13. 2) Add switch to breadboard, connect one of the switch
This tutorial shows you how to read an Analog Devices ADXL3xx series (e.g. ADXL320, ADXL321, ADXL322, ADXL330) accelerometer and communicate the acceleration to the a personal computer. This tutorial was built using the breakout boards from Sparkfun. The adafruit accelerometer breakout board also works, though it must be wired differently. The ADXL3xx outputs the acceleration
This instructable will teach you how to build your 4x4x4 LED cube with Flower ProtoBoard and control by Arduino. Why is Flower ProtoBoard ? not ProtoBoard ? Because of I often use protoboards to test out if a new idea works in practice. I do not use breadboards anymore because I pretty much use only smd parts
