Adjust signal (monostable 555 timer)
Hello everyone
Im building a clapswitch, and i have most of it working
The schematic is here:
![Sensitive-Clap-Switch-550x280 - Kopi.png Sensitive-Clap-Switch-550x280 - Kopi.png](https://www.edaboard.com/data/attachments/16/16157-abbe698e66fb5c23bfdfe392caf3cc9b.jpg)
My problem is after the first op amp, a clap will produce several pulses, and the counter will count all of them, so i need some way to turn these signals into one
My first thought was a Monostable 555 timer, and i found this schematic (R=80 kohm, C=0,1 uF = 0,088 sec)
(I used "out" on the first schematic to "Trigger", and "Output" to "In" on the first schematic)
But i cant get any output on the 555 timer, what am i doing wrong?
Also, is there an easier way to solve my problem?
Thank you
Jeppe Clausen
