Sketch for generating test pulses for the power meter

//Sketch to generate timing pulses to test the power meter (an attiny85 is used, but any arduino will do the job)

/* 
 
 program to simulate the signal as generated from aa speedometer pickup by an arduino duemillenova
 it will be fed into another arduino that contains the power measuring algorithm
