Hi
I've not really done any electronics like this for over 30 years. I've just started getting back into it but need a bit of advice.
I have a electronic drum kick pad that produces a pulse output (from a piezoelectric transducer I think). I want to use that pulse to generate 'closed circuit' lasting about 250ms each time it is triggered. So for each time a pulse from the drum pad arrives the drum sound module effectively sees it as a switch closed for about 250ms. I suspect I can probably do this with a 555 timer using the trigger input. The pulse from the drum pad appears to range from 0.5v (hitting it lightly) up to about 2.5v.:
Soft hit:
Hard hit:
I'm less sure about the output? I don't need to provide a signal as such. Just close the circuit so maybe I just need to send the output to a transistor to switch it 'on'?
Can anyone comment? Do you think I'm on the right track?
Thanks
Mike
