Hey there,
I've did a previous project also with 4017 chips, and it worked fine. The clock input was provided with a 555-timer setup. But now I want to use a "human-controlled" pulse switch to supply the clock input.
I've created a very small test scheme. Just connect pin 8 to ground and pin 16 to the positive pole of the accumulator, connect pin 3 (output 0) to a 5V LED (in series with a 680Ω res, because my accumulator has 12V), and connected the clock-inhibit to ground. The pulse switch is located between the positive pole of my accumulator and pin 14 (clock input)
When I turn the whole thing on, the LED burns (ofc, since pin 0 is on when you switch the 4017 chip on). But my clock signal doesn't do anything. Does anyone know why?
regards,
