Or, an exercise in input and output multiplexing, and working with bits. And a submission for the Arduino contest. This is an implementation of a tic tac toe game using a 3×3 array of bicoloured LEDs for a display, a simple resistive touchpad, and an Arduino to tie everything together. To see how it works, […]

This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. We’ll use conductive thread and sewable electronics so your jacket will be soft and wearable and washable when you’re done. Enjoy! A version of this tutorial is also on my

Introduction The goal of this project was to design and build a gaming device capable of levitating a ping pong ball at varying heights based on the proximity of the user to the device, utilizing a multi-tasking kernel on the ATMega16 platform. The project incorporates a fairly complex mechanical system and utilizes many features of

Wall of Pong is a fast-moving, interactive, laser-based pong game playable on any flat surface. The system uses a digitally controlled laser projection platform to draw a pong ball onto any flat surface. This allows for a large playing area that can be set up almost anywhere. Hand held paddles with embedded sensors are given

The reason for making this project is that I was always fascinated by Conways Game of Life. It’s a great demonstration of the fact that simple things with a very simple set of rules can do wonderful things: spawn more of them, modify themselves, do logical operations, even create Turing machines. I suspect much more can be

I. Introduction This project is a portable battery-powered video game based on the 1984 cult classic PC game “Rogue”. I designed a hardware-based roguelike video game because I am a long-time Rogue addict and thought it would be cool to make a portable plug-and-play imitation. The project involved some basic hardware setup, including a Sega

Introduction: But now I can do this very easily by a simple digital signal processing using a microcontroller. It’s concept is very simple, ie we need to apply a proper delayed feedback in digital samples with in a circular buffer. I did this using an atmega32 microcontroller and it worked fine. This is simple but really an interesting project.

Introduction: This is my first AVR based hobby project and the most successful one compared to my all previous stuff. I am 100% satisfied with this work. Few months ago, I tried to make a wav player using a PIC16F877A. It worked anyway, but the audio quality was not so good for higher sampling rate

This project is used to measure the distance using ultrasonic sensors. The ultrasonic signal passes through the atmosphere to a barrier, which we want to measure the distance. Part of this signal is reflected and travels back to the receiver. The time delay between sending and receiving signals are then determined by distance barriers. The device was designed
