It can divide the input frequency from 3 to 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. I’m not sure how the hardware interrupt is made.

Triple 3-input OR gate. I think in order to make the 74hct work, it will need some supporting chips, just so I don’t need a tremendous number of pins in order for it to work.

I have never used it, but datasneet from the datasheet dagasheet would seem so. Dual 4-input NAND gate. BCD to decimal decoder. Octal edge triggered latch. Triple 3-input AND gate.


74HC85 – 4 Bit Magnitude Comparator

Octal 3-state inverting buffer. You can use datasyeet 74HC 8 bit counter feeding into one side of a 74HC85 magnitude comparatordataeheet feed the other side from a shift register 74HC Quad 2-input AND gate.

Octal 3-state bus tranceiver. I just thought that if I could have something external count the pulses, I could have the Arduino doing something more important. Hex inverting buffer gate.

Dual 4-input NOR gate. Dual 4-bit binary counter. And not the lest, what westfw says! Is there any chance the Arduino might miss this “count reached” signal?

Quad 3-state buffer Hi enable. The counter can be reset with an arduino output. Dual 2 to 4 line multiplexer. BCD counter asynchronous reset. Dual D type flip flop 4-bit. Click on the appropriate section below for the relevant data sheets.

Logic Data sheets Series Component. Dual D type flip flop E-trig. Grumpy Mike, your 74hf85 might be the ticket! BIN counter asynchronous reset.

Quad 2-input exclusive OR gate. Triple 3-input NOR gate. Quad 2-input NOR gate.

For needs like you describe, there is always the option of using a small microcontroller and implement the functionality you need. BCD counter synchronous reset.


74HC85 Datasheet –

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. Quad 3-state buffer Lo enable. Hex 3-state inverting buffer. Triple 3-input NAND gate. I didn’t want to use the Arduino directly.

D More importantly, how fast will these signals be? Octal 3-state D type flip flop. But it will 7hc85 you some 2 PWM outputs for each timer you use. Dual monostable multi vibrator.

Quad 2 to 1 line multiplexer. This is available free of charge from the Adobe web site. I’m unsure if you can use timer0, as that’s also used for millis dqtasheet some other rather important stuff Arduino-wise. We hold data-sheets on many items that are found in the stores inventory.

Quad 2-input OR gate.
