Using an Apple Pro speaker, I made a flashing RGB LED iPod dock for about $35. I recommend reading the entire ‘ible before starting. Also, note that the volume is control from the iPod. It consumes minimal power in shutdown mode, and is controlled by a Teensy. This took me ~3 days to build, and […]

This is where all the work is done to read an interpret the values from the servo and the sensor. If the readings are to erratic then you won’t have nice shapes. Also if you don’t allow enough time to the signals to be sent back then you’ll get false distance readings. So this code
This is a project that I have been working on a few months now and I have completed its build very lately. The main processor used in this project is an Arduino MEGA 2560 which is interfaced with a real time clock called the DS 1307 chip (which gives you the time and date). Both

So far my Arduino projects have all needed only a small number of output pins. In a previous post I talked about moving some of the logic off the Arduino and into other integrated circuits in order to free up pins on the Arduino. While this can help, I’m sure there will come a time

Concept: Very simple, using an Arduino and the play melody basic program, create a music playing speaker out of a vibration motor and a piece of flexible foam. Instead of pulsing signal to a speaker, signal is pulsed to a motor varying how fast it can spin and when it spins. Science behind it (this

First things first, we need to build our circuit. This is the easy bit! We’ll be using the Arduino to control a servo that will rotate our sensor around 180 degrees. The Arduino will then send the value from the distance sensor along with the current angle of the servo to the serial port. Before
**DISCLAIMER** I do not and will not take responsibility for anyone who gets in trouble for this, by either imitating emergency personnel, or using without a permit/lisence. Updates! -I have shortened the code -Changed 16 LED’s to 8 -Changed/added more flash patterns -Renamed variables As promised, this is the ATMega 2650 version of the police

As you might be able to tell from recent posts, I’ve been doing quite a bit of work with an Arduino. I’ve now got at least one project that I’d like to make a little more permanent, rather than it just being a bunch of components on a breadboard. The easiest option would probably be

Ever wanted an LED tree? Well now you can have your LED tree and eat it too (no, wait, you probably shouldn’t).. Step 1: Gather the parts You will need: 1x ATtiny85 10x male header pins Solid core wire, 2 colors A bunch of LEDs 1x Arduino Uno to program the ATtiny Step 2: Program

My last theremin involved a small speaker. Now I’ve replaced the speaker with my PC, using processing to pick up the values from the SRF05 ultrasound sonar distance sensor and play different notes accordingly – which gives multiple possibilities and far better sounds. So to start with check out my previous theremin, the circuit is
