Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller interfacing with an SD SDHC card module and a DHT11 temperature and humidity sensor. The Arduino UNO serves as the central controller, managing data storage on the SD card and reading environmental data from the DHT11 sensor.

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your components and settings, and the loop() function is where the main logic of your program runs continuously.
