Electronics

Ok, as I am also getting back in to electronics, I have now built 2 circuits,  and linked them together.  Firstly a 555 timer circuit,  and secondly a 4017be decade counter linked to some LEDs,

The 555 is wired up as a Astable the output is linked to the counter input of the 4017

This is used for the led sequencer

I am only using 4 leds at the moment but it works.
