Eric , sorry I understand about wiring I.E. from A to B / C to D etc BUT when you said ,, not to worry
Its the not so finer points of electronic, I dont have a clue about.
The current limiting resistor I got from an online program for working out resistors for LED's ,, Now I am confuzed ,, I see where you get the 20mA LED ,, and ESR are rated at 25mA 2v2 for green but glad I miss read parts as i checked on-line and they are not all the same, 3mm r rated as
Green 2v2 25mA
red 2v0 25mA
yellow 2v1 30mA
but
blue are rated at 4v5 30mA and aprox same brightness
Oh heck UMMMM can we please get back to the 555+4017 and maybe if it works I'll add a single LED to each O/P for now and worry about the trans & LED's after its constructed or does that pose problems.
Thanks for helping me out
Steve
