Circuit Documentation

Summary

This circuit integrates various components controlled by an Arduino UNO microcontroller to perform a range of functions. It includes a heart pulse sensor for biometric sensing, a buzzer for audio signaling, an L298N DC motor driver to control two hobby motors, a SIM800L module for cellular communication, and a 12V battery as the power source. The circuit also features a basic flex resistor and a yellow LED with a resistor for visual indication. The Arduino UNO manages the inputs and outputs, interfacing with the sensors, the motor driver, the communication module, and the LED.

Component List

Arduino UNO

A microcontroller board based on the ATmega328P. It has digital input/output pins, analog inputs, a USB connection for programming, and power management features.

Buzzer

An electromechanical component that produces sound when an electrical signal is applied.

Heart Pulse Sensor

A sensor used to detect the heartbeat rate of an individual.

L298N DC Motor Driver

A module capable of driving two DC motors or one stepper motor with current control and thermal protection.

Motor Amarillo Motorreductor Hobby (x2)

Hobbyist DC motors with gear reduction for increased torque.

SIM800L

A GSM/GPRS module that allows cellular network communication for voice calls, SMS, and data.

Battery 12V

A 12-volt battery that provides power to the circuit.

LED: Two Pin (Yellow)

A yellow light-emitting diode used as a visual indicator.

Resistor (200 Ohms)

A passive two-terminal electrical component that implements electrical resistance as a circuit element.

Basic Flex Resistor

A variable resistor that changes its resistance when bent.
