Hello all,
I need a circuit that will reverse the voltage applied to a small coil with a variable duty cycle, nominally 1s. The intended input is 9VDC.
The only circuit I found to accomplish this with a 555 is attached. The problem is that values for R1, C1, and the output caps are not included, so I was hoping someone had a similar schematic with values, or accompanying lookup table w/values for a range of output characteristics.
Thank you!
Mike
