I'm working on a Motor Grader Simulator without an engine. I'm trying to simulate a 72 tooth gear on a crankshaft with 2 teeth missing (marks top dead center for cylinder 1). I have a signal generator, but I am unable to turn it off for 2 cycles, so I wanted to create a circuit on a bread board to do it. I was thinking of using a 4017 (count to n and recycle) to count up to 72 to reset another 4017 (count to n and halt) that halts at 70, but the 4017 doesn't have an output that I can hook up to simulate the sensor. Is there a counter that has a single output that I can simulate the output of the sensor? Reference voltage on the sensor is 5 VDC and the ECU is looking for an return of .2 to .5 VDC - 4.5 to 4.8 VDC.
