DigiSpark PB/LED test

[last updated: 2016-07-31]

//
// Program name: DSPBtest01
// edited for DigiSpark from PBtest
//
// Purpose:
// blink routine for onboard LED at setup
// blinks 1/sec heartbeat on board LED
// lights output LED when PB is pressed
//
// Edit History:
// rev. setupBlink_heartbeat: first rev
// rev. PBtest: added code to drive LED w/ PB
// rev. DSPBtest: edited for DigiSpark
// added PB & output LED
//
// Program operation/flow:
// blink on setup routine run at start & end of setup
// heartbeat done as first task in loop, millis-timed
// reads input from PB and lights LED accordingly
//
// Hardware configuration:
// P1 (for DS model A) reserved to drive onboard LED
// output LED on P4
// input PB on P5
