D More importantly, how fast will these signals be?

I didn’t want to use the Arduino directly. Dual 2 to 4 line multiplexer. Triple 3-input OR gate. Octal 3-state D type flip flop.
I also wrote a somewhat lengthy mumbling answer combining presettable counters and whatnot, but then I remembered there are those things called “divide-by-N” counters. Hex 3-state inverting buffer. Quad xatasheet AND gate. Dual D type flip flop E-trig.
Quad 3-state buffer Lo enable. Quad 2-input OR gate. Hex 2-input NOR enable buffer. I’m unsure if you can use timer0, as that’s also used for millis and some other rather important stuff Arduino-wise.
Is there any chance the Arduino might miss this “count reached” signal? BIN counter synchronous reset. BCD to decimal decoder.
Hex inverting schmitt trigger. But it will cost you some 2 PWM outputs for each timer you use. Dual 4-input NOR gate.
Dual monostable multi vibrator. Quad 2-input 3-state mux.
I just thought that if I could have something external count the pulses, I could have the Arduino doing something more important. I don’t know how often the pulses will be coming in, because it will depend on what the sensor is detecting. Grumpy Mike, your circuit might be the ticket! Octal edge triggered latch. Octal transparent inv op latch.
I’m not sure how the hardware interrupt is made.

Just for the record, my reference to any “lengthy mumbling answer” was not intended for you, datawheet something I didn’t include after all. You can use a 74HC 8 bit counter feeding into one side of a 74HC85 magnitude comparatorthen feed the other side from a shift register 74HC You all may be right, I may be trying to do something that the Arduino can already do, but I just thought that if I could do it off board, I could save the processing cycles for something more important.
Into the feed your number with dstasheet shift out tutorial. BIN counter asynchronous reset. To view Acrobat files you 74h8c5 install Adobe Acrobat Reader. Quad 2 to 1 line multiplexer.
74hcc85 3-input AND gate. Dual 4-bit binary counter. I am doing a handful of analog readings which as I’ve read take significant amount of timeI am currently driving 2 servos PWM outputand I still have more features I am trying to add. Dual D type flip flop 4-bit.

I’d suggest two or three shift registers latchablelike the 74HC It can divide the input frequency from 3 to Schmitt Hex inverting gate. We hold data-sheets on many items that are found in the stores inventory.
Quad 3-state buffer Hi enable. For needs like you describe, there is always the option of using a small microcontroller and implement the functionality you need. Quad 2-input NOR gate. I didn’t see your answer until after! I have never used it, but judging from the datasheet it would seem so.
Quad 2 to 1 line mux Inverter. Octal 3-state inverting buffer. Quad 2-input NAND gate.
