sleepBlink Example – eS2 Pro

This is an example sketch designed to demonstrate the power sleep functionality of the energyShield 2 Pro. In this example, the sketch blinks an LED three times and then commands the energyShield to turn the power off for four seconds. After four seconds the energyShield re-enables the power and the sketch restarts.

  This sketch blinks the pin 13 LED three times and       
  sleeps for 4 seconds. These results is an approximate   
  20% duty cycle for power comsumption. That means that   
  this blink sketck will run 5 times as long as the       
  standard blink sketch will run on the same battery.
