ATtiny breadboard headers

 

ATtiny breadboard headers
These little breadboard headers are very handy. They occupy only one more row on each side as a controller would need. These tiny controller boards are build to provide a quick start for projects with 8 and 20 pin AVR microcontrollers, e.g. ATtiny13, ATtiny45, ATtiny85 and ATtiny2313. [more]

Quick AVR - An AVR development board

 

Quick AVR - An AVR development board
This is for those of you that want a quick prototyping system that will plug into a breadboard without taking up too much space. It will mount at a 90 degree angle to the breadboard like a video card on a computer motherboard.[more]

ARobot Light Detector

 

ARobot Light Detector
ARobot Light Detector
This application explains how to make a light detector for ARobot. This can be used to tell when a light is on or off, whether the robot is inside or outside, or for light following. This is a simple expansion and does not require soldering if using a breadboard. It does assume that you have attached a breadboard and an expansion cable to the ARobot (see the breadboard/perfboard application note). This circuit and the light sensor could be mounted and soldered to a perf board and located to a movable head. [more]

Standalone AVR Music Player “Sound Bug”

 

Standalone AVR Music Player โ€œSound Bugโ€
Using the term ‘music’ liberally here, it will play a squeaky, but recognizable stream of audio, generated from MIDI files.It’s a satisfying little project that is a nice change from the typical beginner embedded controller blinking LED project(s).You can’t get any simpler than this: a piezo buzzer, a power supply (3×1.5 AA), a breadboard, and an AVR (ATmega16, but almost any will do).To make new music files, you’ll also need Perl and a program such as MIDICSV to convert the files.[more]

Experimenting with Wireless Transmission

 

Experimenting with Wireless Transmission
This simple circuit demonstrates wireless transmission. You can send Morse Code
signals over distances of a few meters to any AM radio. The antenna is created by winding 3 meters of wire on two 12 cm sticks secured 6 cm apart. Any wire is OK for the antenna.The switch is constructed from a small piece of aluminum cut from a cookie sheet and all of components attached to a piece of wood(the antenna, breadboard and switch).
