Hello everyone. I am new here in the site. And am a beginner in electronics. Am working on a small project- SOUND ACTIVATED BURGLAR ALARM. I'v built the sound amp. around lm386 and 741. I'v also built an oscillator 4 the alarm.
My trouble nw is to build a LATCH SWITCH that will take the signal from the amp and use it to trigger the oscillator & remain on until a reset button is pressed.
I hv transistors BC141 & 2N2222 & IC- CD4013.
Pls hlp me in designing this.
