Hello,
I want to activate a 555 timer (astable mode) with a PIR. The PIR sends a positive signal for a certain time, when motion is detected - how can I use this signal to activate the 555 timer?
The astable 555 timer is already built, but starts working immediately when the circuit is powered. Thanks for assistance.
