Hex inverting buffer gate.
You all may be right, I may be trying to do something that the Arduino ratasheet already do, but I just thought that if I could do it off board, I could save the processing cycles for something more important. Hex 3-state inverting buffer. Grumpy Mike, your circuit might be the ticket! Dual 2 to 4 line multiplexer. Quad 2-input NOR gate. Quad 2 to 1 line multiplexer. A quick googling gave me theor 74HCT, which might fit the bill. Quad 2-input exclusive OR gate. I’m unsure if you can use timer0, as that’s also used for millis and some other rather important stuff Arduino-wise.
Hex inverting schmitt trigger. I didn’t want to use the Arduino directly. Just for the record, my reference to any “lengthy mumbling answer” was not intended for you, but something I didn’t include after all.
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. I have never used it, but judging from the datasheet it would seem so. Octal 3-state D type flip flop. Triple 3-input NOR gate. 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.
I don’t know how often the pulses will be coming in, because it will depend on what the sensor is detecting. I just thought that if I could have something external count the pulses, I could have the Arduino doing something more important.
The counter can be reset with an arduino output. Dual D type flip flop E-trig.
Triple 3-input AND gate. Click on the appropriate section below for datashet relevant data sheets. This is available free of charge from the Adobe web site.
Quad 2-input OR gate.
, 4-Bit Magnitude Comparator, SOIC, 74HC, 74HC85
Dual D type flip flop 4-bit. Dual 4-input NOR gate. I think in order to make the 74hct work, it will need some supporting chips, just so Datashwet don’t need a tremendous number of pins in order for it to work. Triple 3-input NAND gate. BIN counter synchronous reset. Quad 2-input 3-state mux.
And not the lest, what westfw says!

Octal 3-state bus tranceiver. 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 Quad 2-input AND gate. To view Acrobat files you must install Adobe Acrobat Reader. But it will cost you some 2 PWM outputs for each timer you use. Logic Data sheets Datawheet Component.
BCD counter asynchronous reset. Octal 3-state inverting buffer. Hex 2-input NOR enable buffer. I’d suggest two or three shift registers latchablelike the 74HC Quad 2-input NAND gate. We hold data-sheets on many items that are found in the stores inventory.
Octal edge triggered latch. Dual monostable multi vibrator. I didn’t see your answer until after! D More importantly, how fast will these signals be?
Dual 4-input NAND gate. For needs like you describe, there is always the option of using a small microcontroller and implement the functionality you need.
Quad 3-state buffer Hi enable. Schmitt Hex inverting gate. Triple 3-input OR gate. Octal transparent inv op latch. It can divide the input frequency from 3 to BIN counter asynchronous reset.
