Circuit Documentation
Summary
This document provides a detailed overview of a circuit that includes a 1 Channel Relay, a MAHIR 1.mini power source, a METAL TOUCH sensor, and a Piezo Buzzer. The circuit is designed to control the relay based on the input from the METAL TOUCH sensor, and the Piezo Buzzer is used to provide audible feedback.
Component List
1 Channel Relay 5V
- Pins: VCC, GND, IN, NC, COM, NO
- Description: A relay module that allows a low voltage circuit to control a higher voltage circuit.
- Purpose in Circuit: To control the connection between the Piezo Buzzer and the power source.
MAHIR 1.mini
- Pins: GND, 3.7v
- Description: A power source providing 3.7V.
- Purpose in Circuit: To supply power to the other components in the circuit.
METAL TOUCH
- Pins: D0, VCC, GND, A0
- Description: A touch sensor that detects metal touch.
- Purpose in Circuit: To provide an input signal to the relay based on touch detection.
Piezo Buzzer
- Pins: pin 1, pin 2
- Description: A buzzer that produces sound when powered.
- Purpose in Circuit: To provide audible feedback when the relay is activated.
