What is Emotional Stress Indicator Circuit Diagram about?
This document describes the circuit diagram and components for an "Emotional Stress Indicator" device. The circuit uses touch pads to detect minute voltage variations from skin contact, which are amplified by a transistor and fed into an integrated circuit. This IC drives different colored LEDs - green for relaxed states, yellow for intermediate stress, and red for high stress. It can also sound a piezo buzzer at high stress levels. The circuit is assembled on a small perforated board or PCB and enclosed in
