Step 1 Parts

Parts can be obtained from any of a number of electronic suppliers. Because of the space constraint, most of the components are required as indicated. Everything just barely fits; make sure that any substitute parts don't take up additional space. Do not substitute for the ATtiny84 unless you are absolutely certain that the pins correspond. The links following the parts are to DigiKey and All Electronics.
