This simple project illustrates how to move from an Arduino + breadboard setup, towards an Arduino on the breadboard (‘bare bones’), towards a bare bones Arduino soldered on a prototyping board, finally built into a nice sturdy housing (cookie box).

This project again illustrates how to move from a (temporary) prototype using an Arduino board and breadboard towards a more permanent soldered (low cost) solution using the ATmega328 chip. The idea is to use a cheap wall wart to deliver
