I am not an electronics guy but need a circuit that will do the following:

there will be two separate momentary buttons as inputs and one output
pressing PB1 will give a one pulse at the output
pressing PB2 will give a two pulse at the output

The output will be wired into an input on my datalogger.

Any ideas? is this something that can be purchased off the shelf?

Thanks.

 

I can see how I can do it with microcontroller, but that might be more hardware than you need.

 

What output levels?

What timing and debouncing is required?

It could be as simple as connecting button one direct and using circuit that triggers on change of state from the second button. (twice with one press)

Or maybe a "smart" timer or plc.

An ic timer, latch, and counter?

 

Might try 3 555's cascaded, first gives 2 pulses & debounces SW, 2nd gives spacing between pulses, & 3rd gives a single pulse & debouncing if pulses are longer than about 20 ms.
