I have added a follow-on to this Instructable: http://www.instructables.com/id/Cheap-and-Easy-MP3-Shield-for-Arduino/ The follow-on shows you how to design, etch and build a PCB shield to connect the MP3 to the Arduino. Replaces the analog switches with a 74HC244. SIngle layer board with large surface mount component design. Only 5 thru holes. Take a look. Ebay abounds with sales …
Arduino isn’t limited to taking input from sensors: you can even connect up a full-size PS/2 keyboard just as if it were a “real” computer and type away! Connecting a keyboard to an Arduino may sound a bit odd (after all, it’s just a little microcontroller) but keep in mind that an Arduino actually has …
Synthesized speech was for a long time the Holy Grail of computing, and back in the 1980s when a 4MHz CPU made your computer the fastest machine in the neighborhood it just wasn’t practical for software to create intelligible speech. In those days the only sensible way to generate speech was to offload the task …
There are quite a few geiger counter instructables. The difference with this one is that I wanted to give it a modern interface, similar to smart phone touch screens, that anyone would feel comfortable using. The reason for this is that I want to use it as an educational tool to teach kids (and interested adults!) about …

We finish up our project using I2C on the Quark D2000 development board with the addition of a color sensor and an object color identifier program. Finally, we revisit interfacing the BH1750FVI ambient light sensor using asynchronous mode I2C.Before continuing in this article, consider reading through part one of the article: Quark D2000 I2C Interfacing: Add …

In this article, we are going to read the colors using the TCS230 color sensor (RGB Sensor) and Arduino Uno. The TCS 230 color sensor senses the color light by using the photodiodes. The sensor converts the readings from the photodiode into a square wave by using the light to frequency converter. The frequency of these …

Have you ever wondered how migratory birds manage to have such an amazing sense of direction despite being so generally clueless? They can sense the Earth’s magnetic field with what is basically a compass built into their body. Wouldn’t it be cool to feel what that’s like? The following instructions are loosely based off of …

There are many types of security systems used all over the world and Digital Code Lock is one of them. We have already covered many digital locks with simple 16×2 LCD using Arduino, Raspberry Pi, 8051 etc. Here we are going to build a Smart Phone Controlled Digital Lock using TFT LCD and Arduino Mega. This lock can be controlled wirelessly via Bluetooth, using …
