In this Instructable I am going to show how to make a program in Processing that analyzes sound on your computer and sends data to an Arduino that controls an LED matrix to show the spectrum analysis. I will be explaining where to get materials, explaining the coding and wiring needed and providing example programs

What is does: It searches for the brightest light source like the sun. Step 1: How it works How it works: I’d made a sensor of 4 LDRs with sheets between them The withe stips are the LDRs When the stick on top is righted to the sun or the brightest point the four

This instructable shows how to build a shield to connect devices that send MIDI signals (e.g. a masterkeyboard) to an Arduino. The basic schematic is derived from: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1187962258/ Step 1: The schematic Basically the schematic is just an optocoupler with some resistors to decouple the MIDI device from the Arduino. Note that the DIN connector

RFID tags are all over the place. They’re used in building access control systems, passports, inventory tracking . . . This instructable will show how you can use an Arduino and a few simple components (wire coil, transistor, capacitor, resistor) to make a device that can spoof an 125 KHz (low frequency) RFID tag.

This summer I wanted to combine my two loves of plant science and engineering. Thus I am constructing my very own greenhouse in my backyard. I am an undergrad, and as any former student knows, this means I move around constantly, and I am not always around to take care of my vegetable garden. I

This project slightly modifies the Google Android sample app called “Bluetooth Chat” so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno. Functionality: Android talks to Arduino 1. Run the Android “Bluetooth Chat” sample app (after we modify the app in

What’s simpler and dumber than a button, you ask… I say: behind a button, unexpected things can hide. And within a program that does various things, handling a button can be tricky. The nice thing is that interesting functions can be built with a simple dumb button. This tutorial will address these aspects: wiring and

A Binary Clock! I was recently looking at some binary clocks and I felt like Why not? I have everything to make one and I don’t have a clock in my room. So I decided to build one and here it is. Hope you Like it and maybe build your own. It’s a cool project

This instructable will show you how to make your own arduino based watch that tells time using a matrix of LEDs. This is my first instructable, so if something is unclear leave me a comment or send a message! I was inspired by all the cool LED watches that I saw on this website: http://www.tokyoflash.com/en/watches/1/
