I need a circuit diagram for a simple piezoelectric audio buzzer and led light flasher in one handy circuit board?
I am trying to build a simple circuit that has a piezo electric buzzer and an led light flasher that runs on a 9V battery. The idea is that, this circuit is a wearable (a necklace prototype) that acts as an alert system - the circuit needs to be compact. All I want for it to do is, with the flip of a switch, the buzzer sounds and the LED light flashes. I am a beginner when it comes to building circuits. Can some one please provide me with a circuit diagram?
Thanks for your help!
