I am currently messing around with this circuit:
http://www.555-timer-circuits.com/knight-rider.html
It is running on a 9v Battery, and I have found that running on 9v, doesn't last very long. So I am trying to run this through 6 volts (Battery Holder with 4 AA batteries).
If I connect an LED directly from the 555 output, it flashes and is very bright. But once, I connect the output of the 555 to the clock input of the 4017 chip, the lights work as planned, but they are much dimmer. In the explanation, it says that the LED's are running at 7mA, and I would like to get that up around 15mA, so my super bright LED's will glow!
So, why is the LED so dim running off the 4017?
