Seven Segment arduino library, drive with ic 74hc595 and ULN2803, we create modul seven segment 3" Commond Anode. This module easy to use, low price and high quality. This libray have four function, perhaps we will update function.
first function:
void mikro7::on(); this function to on all of your segment, this we use for check does all seven segment good? void mikro7::off(); this function to off all of your segment, perhaps for one condition that we want to decrease power uses
