this is a revised schematic of Boncuk with the 7555 circuit (added the pullup resistors. The pulse has a problem??)
the outputs from the 4017 can only supply a max of 10ma so I revised the output transistors
the base only draws 2 ma apx, the LED = 20ma, the data select linres only need .5+ - Vcc voltage so as I connected to the LED / resistor junction = 2v apx.
this is getting to look better all the time.Hope it dosn't end up like that bike alarm where the kid basically gave up because its tooo hard.
hopfully he will wake up and realize the pic method is more than he can chew
