Since the only light I got is the LED from arduino kit, I decide to build a LED flash light.
Collect all parts neeed.
- LED 8x8 matrix
- jumper cables
- arduino uno board
- bread board
- USB cable
- potato chips（very important）
Upload the example code to Arduino Uno board.
And it flashed!
Add a battery to the Arduino Uno board to make it portable.
Tutorial: I followed this tutorial to make it.
