Circuit Documentation

Summary

This circuit integrates an Arduino UNO R4 WiFi with a Heart Pulse Sensor and an SHT1x-Breakout sensor module. The Arduino serves as the central processing unit, interfacing with the Heart Pulse Sensor to read pulse signals and with the SHT1x-Breakout to monitor temperature and humidity. The circuit is designed to be powered by the Arduino's 5V output, which is distributed to the other components. Ground connections are established between the Arduino and each sensor to complete the power circuit. The sensors are connected to specific analog and digital pins on the Arduino for data communication.
