angrybox

An angry box.

Wiring instructions:

• Connect a small speaker between Arduino digital pin 11 and GND.
• Connect a button between Arduino digital pin 2 and GND.

To move this from the Arduino board to a stand-alone ATMEGA328 chip, you'll need to set the ATMEGA fuses to tell it to use the internal clock. Follow the instructions at https://www.arduino.cc/en/Tutorial/ArduinoToBreadboard.

In this configuration, you'll be able to build this project with nothing more than the switch, speaker, ATMEGA chip, and battery.
