UPDATES Feb 20, 2013: In response to a question by student Hala Abuhasna if you wish to use the .NET Serial class, use the naming convention “\\\\.\\COMn” and replace n with a number > 9 to define your com port for COM ports above 9 such as COM10, COM11, etc. Mar 23, 2012: Featured on […]
Disclosure: This project operates the ATmega328-P-PU outside the published ATmel specifications: According to ATmel, the 328P requires slightly over 3.3V to reliably start the oscillator at 16MHz and to otherwise perform acceptably. Lab testing here at SofKinetics has shown that the ‘board-duino’ 328P-PU can withstand below freezing and above 130F temperatures and that the 16MHz […]
Introduction We aim to introduce young students to engineering and teach them about solar energy; by having them build a Helios as part of their curriculum. There is an effort in engineering to push energy generation away from the use of fossil fuels and towards greener alternatives. One option for greener energy is to use […]
I made this box for my music project to our school. This is only tutorial for the box, no for playing melody. It´s based on serial connected switches. You will need: Some wire 6x switch 1x LED 1x 330 ohm resistor 5x 2000 ohm resistor (etc.) 1x 10 000 ohm resistor 1x plastic box small […]
Hello, and welcome to my instructable for a washing machine countdown timer. The timer is operated with the very popular Arduino micro controller. See here for more information. Arduino Home Page Aim The aim of this project is to be able to delay the start of the washing machine by a few hours. This is […]
Use a Classic Nintendo controller to lock and unlock your door! The output from the Controller is read by an arduino and it looks for a particular combination of buttons, once the combination is entered it sends a signal to eject a Cd-Rom Drive which pushes or pulls the lock. I started making this project […]
Have you ever wanted to make a line following robot but the infrared sensors were too expensive for you? Do you want to upgrade the robot in my other instructable? Well this instructable comes in two stages, Stage 1 is the prototyping stage, where you build the circuit on the bread board and debug it […]
Introduction: Okay, I cheated. Any similarities between previous Instructables uploaded by me and the graphics, pictures, text and / or programming code is purely intentional. It certainly made putting this one together a whole lot easier. This Instructable is my Arduino version of the Rock Paper Scissors Lizard Spock game devised by Sam Kass and […]
This is a funny project that makes our plants “talk” to us. It’s very simple and you can create it in few hours. We use a sensor to read the soil moisture of our plant and a led matrix to dislay how the plant “feel”. You can use an ATtiny85 as a microcontroller. Step 1: […]
How often do you ever forget to feed your fish? Well, for me I don’t forget that much. I just couldn’t go out town for a couple of days and also be ridiculous if I should bring my tank along. When I won a Sparkfun RedBoard from Sparkfun Analogy Contest, this was the first project […]
