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 […]

This project consists of an interactive Arduino-based Halloween decoration referring to a witch cauldron. As you position your face in front of the cauldron and you get close, the eyes start moving around. At the same time, when there is very low light in the room the program turns on a LED light located in
Every now and then you might be interested to input text to your arduino project. You can do it using Serial input but this would require Arduino to be always connected to a computer. In this tutorial I would show you how to implement text input using the small OLED display and 5 key keyboard
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
For this Instructable, I have made a primitive musical soundboard using an ultra sensor as a keyboard. Here I will show you the basic steps on how to create such a device yourself. Later on, in December, I will demonstrate to you how to make a more complex or soldered version of this soundboard with

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
