Overview: This instructable will construct a series of custom sensor modules and an Arduino shield. Such modules are available from many different sources, but fans of the Instructables website would probably find satisfaction in making their own. Each module will be a set size of 1.5cm by 2.5cm and employ a three pin connector of […]
Okay so the Title is indeed a bit of a mouthful lol ! Ive been needing to mess around with a desire for MORE Input/Output pins than the Arduino UNO and nowadays the UNO uses an Atmega328 microcontroller, & its limited to only about 20 Input/Output pins 🙁 Well if you’ve been messing around with […]
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 […]
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 […]
Introduction We designed a system for wirelessly controlling relays and monitoring current. This is used for a home load simulation. By wirelessly turning relays on and off by sending commands from a PC to a microcontroller we can change the total load (current) to our simulated home. For wireless communication, we used XBee Series 2 […]
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 […]
