This Arduino project was part of an Association of Mechanical Engineers (ASME) contest to create an Autonomous Material Sorter. The sorter was to sort four glass bottles, four plastic bottles, four Tin cans, and four Aluminum cans. There were requirements such as size of the bottles and size of the machine. The machine had to […]

This semester at college, I am in a class called Computing and Craft which is about incorporating circuitry and micro-controllers and craft to bring our projects to the next level. For our first big project, I decided to make a raincoat the reacted to light and water. Being from California and going to school in Massachusetts has
Have you ever made a city out of Legos? I know i have built many of them but they all missed something… Traffic lights! So i decided to make my very own traffic light setup from my arduino board. Step 2: Get the components I assume you already have an adruino board, and maybe also
I have a late 80’s VW and the gauge cluster has 5 dummy LED locations underneath the other warning lights. Well I was tired of the m not doing anything, so I decided to do something about it. I came up with the idea to put a lateral gravitational force mater (G Meter) in there
As a follow up to the Arduino Audio Input tutorial that I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino’s analog input and determines the frequency. The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes. I’ve also turned the LED attached to pin
Are you the kind of person who’s not good with managing keys and always have to try each key for every other lock? Well don’t worry, just grab a little bit of motivation and your maker tools to innovate your very own voice controlled smart key holder. Because there’s no problem too small or big
In the past few years, a number of synthesizer manufacturers have been releasing “desktop semi-modular” instruments. They generally take the same form factor as the Eurorack modular synthesizer format and most are probably intended as a gateway drug into the world of modular. (As addictions go, it’s one of the safer ones.) I fell for

Two other tutorials I have written step you through the basics (Arduino 101) and how to create a really basic data logger (Arduino Datalogger – simple). This tutorial will step through how to attach servo motors, and use temperature sensor to move it! The premise is that often, you want to respond to some input
The Ultrasonic Theremin is an Arduino project that uses a cheap theremin to teach sound waves. By changing the distance of my hand to the device, I am changing the frequency of the sound waves. Also, moving a potentiometer changes the amplitude of the wave. This can be used as a science lesson about sound
All the versions of ultrasonic radars I have found for arduino devices (Arduino – Radar/Ultrasonic Detector, Arduino Ultrasonic Radar Project) are very nice radars but all of them are “blind”. I mean, the radar detects something but what is it detecting? So I propose myself to develope a system able to detects objets and identyfy them.
