Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike incandescent bulbs, they don't have filaments that burn out, they use less electricity, and they don't get especially hot. They're illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The life span of an LED surpasses the short life of an incandescent bulb by thousands of hours. Because of these advantages, tiny LEDs are one of the most popular technologies used to light LCD TVs.

This project is a miniature and extremely basic version of minesweeper using the LED 8by8 Matrix and the joystick. The code selected a random LED and when the Joystick control gets closer to the selected LED a buzzer will sound higher pitched and faster between sounds. To select the LED that one believes is the answer press down on the joystick (axis-z). A red or Blue LED lights up, Red means the answer is wrong, Blue means the answer is correct.
