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 […]
Part 1 – Embedded Programing A Morse Code Receiver and Transmitter This week’s assignment was to program the board we made two weeks ago to do something, with as many different programming languages and programming environments as possible.I wanted to use all the features I have on my board – the button, the LED and the serial […]
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 […]
I wanted to build a Nixie clock driven by an Arduino and found a few places on the internet, but none were 100% complete to get it working from the beginning to end. I either found bad wiring diagrams, bad code in programs or bad supporting literature that really slowed down my progress, so I […]
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 […]
Designing hardware logic circuits can be fun. The old school way to do this was with NAND gates, on a bread board, wired up with jumper wires. This is still possible, but it doesn’t take much before the number of gates gets out of hand. A newer option is to use an FPGA (Field Programmable […]
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 […]
