    At the moment i have connected a 555 in astable mode and connected its output to the 4022be i've connect pin 8 and 16 with a 100nf capacitor, i've connected pin 16 to positive and pin 8 to negative, to get divide by 7 i connected 15 (reset) to pin 5? not sure if thats correct. I have more questions but would like to solve this first.

    What are you building?

    Why are you connecting reset to pin 5? That's the 7th output, so the counter would count from 0 to 5 (6 pulses) and then go back to zero on the next pulse. I think you want to connect pin 15/reset to pin 10. That's the 8th pulse.

    Hello,

    What is your intention with the coils being fired after eachother?
