This is a simple Arduino sketch that was originally designed to experiment with arrays and the built-in timing functionality. I based it on the tutorial sample code http://www.arduino.cc/en/Tutorial/Knock The system consists of a piezo sensor connected to an analog pin that listens for a knock from the user. The Arduino then stores the time the knock […]
For science fair this year, I felt like building something instead of doing an experiment. All I needed to do was look around Instructables for a project idea. I was inspired by njkl44’s robotic hand since it reminds me so much of stuff out of science fiction movies. My goal was to create a system […]
Hello everyone! This instructable is a tutorial that will guide you on using the Capacitive touch sensors with Arduino. A Capacitive sensor is a kind of touch sensor, that requires little or no force to activate. In this Instructable about capacitive touch sensing, I’ll show you: How Capacitive Sensors work How to use them with […]
UPDATE: Added Schematic, Top Layer PCB, Bottom Layer PCB, and both Top, Bottom PCB images When I finished the “RevIO” – an Arduino Clone that has the different way of exposing pins usage. I decided to go further to the next project. To test my “RevIO” board that it could do the bigger task than […]
This is a tutorial for using the 7-Key Slider/Wheel Breakout from Rachel’s Electronics. I’ll show you how to solder up the header pins for maximum usability. Rachel’s has the QT1106 datasheet on their site, and a great arduino library for this breakout. The kit from Rachel’s Electronics comes packed with cool stuff: QT1106 breakout with […]
My goal for this project is to make a watch with selectable dials, stopwatch and millidays. This idea started with an Aprils fools prank about metric-time. (http://www.youtube.com/watch?v=K35xG1buyFA) First I wanted to make a metric clock but soon this idea evolved from a metric watch into an open course watch. I knew that it would be […]
A few years ago, I became a dog owner for the first time. I didn’t like leaving Cody in the kennel alone all day. I had a webcam on him, but I couldn’t watch it all day long. What if he was in some kind of distress? What if there was a emergency at the […]
Can you believe that we live in an age where you can touch an object (any object – if it has metal on it) and a light will turn on in your loved-one’s space – even if they live in a different city, state, or country!? You could tell your loved ones or friends when […]
When I say simple, I don’t mean use a speed control. But control the motor directly without any external circuitry. Here’s how: How this came about: I recently was working on an instructable about charlieplexing with an arduino. And I was wondering if the same principle would work with motors to some extent. So I came […]
These are step by step instructions for assembling the 8×8 LED Board kit from moderndevice.com. I had never played with LED displays before using this kit. I suggest reading through all the assembly steps BEFORE starting to solder because assembly order DOES matter with this kit. Overall, this is a very simple assembly. It does […]
