Description
About the Circuit:
The heart of the circuit is a musical tone generator IC APM993D (IC1). This is a programmed 1024 note ROM memory IC, which has inbuilt oscillator and tone generator.
Touch plate is connected to base of transistor T1. When the plate is touched, T1 conducts and IC1gets triggered. Hence it generates a musical tone. The output at pin 14 of IC is driven by transistors T2 in turn drives 8W Loudspeaker.
Care should be taken that battery supply should not be greater than 3V.
