Door LEDs Bread Board Experiment 03



Here is a rework of the 555 Timer I.C. diagram other than that it's pretty much currently wired exactly the same as before, just playing about with the LEDs light up sequence. I have no doubt it will get a little more complicated if or I should say when we add the chaser sequence and perhaps a different way that the tone is played or delivered.
