Connecting the AVR Dragon Programmer / Debugger to a Breadboard Circuit

An AVR microcontroller board will usually have a header for connecting a programmer / debugger such as the Atmel AVR Dragon. This is not the case when building a microcontroller circuit on breadboard.

This tutorial shows how to connect the AVR Dragon to an AVR microcontroller breadboard circuit for programming and debugging the microcontroller.

Tutorial 19: Arduino Dice

In this tutorial you will build a dice that is shaken by holding the button in and thrown by releasing the button. The shake, throw and number thrown are animated and displayed on a seven segment display.

A 74HC595 IC is used to interface the 7-segment display to the Arduino, using only 3 Arduino digital pins.
