MIT has developed a fantastic visual programming language called Scratch. It is also an amazing learning tool for children, because it is simple, cute, and by providing interaction with the real world by a board called “Scratch Sensor Board”. This Instructable shows the development of a shield for Arduino that can interact with Scratch and replicates the […]
Setting up an Arduino on a breadboard has become a process I have grown to love. Within a few minutes you can have a fully working Arduino platform to work with as you will see in this tutorial. There have been several occasions when I was at school and quickly put together one of these […]
With this device you’ll be able to: take pictures from anything you can sense or detect: – movement – sound – … You don’t need to modify your camera or flash for this. It’s compatible with the old High Voltage flashes and the new TTL ones. Why I did this project? A friend of me […]
This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs. The schematic shows that wiring the […]
Hello everyone! Today I present you : Arduino Joystick! One day I was checking the inside of old joystick. System wasn’t that hard to understand, so I thought of making my of system. The whole build is made only by me. I didn’t check the internet pages about joysticks etc. What is it? It’s a […]
Since I had a lot of ATtiny2313s lying around I wanted to do something cool with them, I thought for a while and then decided to make a simple wall avoiding robot with the ATtiny2313, an ultrasonic sensor and 2 motors. Its an easy to make and simple robot which runs on a very small […]
The Problem: You want to restrict the time when your pet is allowed to go outside. This could be because the neighborhood is not safe for your cat or small dog at night (marauding coyotes comes to mind). But you would like your pet to be able to come in at any time. The Solution: Pet […]
What do I need to start? The hardware requirements to start is: *Note: where can I purchase the material with all the components to build myself the system: http://iwup.altervista.org/shop/reference_list.pdf 1.-) Arduino UNO with USB cable 2.-) Ethernet Shield Arduino 3.-) Relay (for arduino 5 V) 4.-) Router Belkin (we recommend N150 or N300), also TPLink […]
After I built R/C Lego Car, that used hacked motors and motor housings from the toy Car and toy R/C cars. I realized most of the parts from that toy R/C car that I took the motor out of became wasted. This way was not very practical or not so “green” at all. So I decided […]
When I was in the 8th grade, I was intrigued while playing the motion games on Nokia 5800. I was thrilled, how I could control the racing car by only tilting the phone. I used to dream of making this same car in the real world. Now, in 11th grade ( Age 17) having got an Arduino […]
