This circuit features an ESP32 Wroom Dev Kit as the main microcontroller, interfaced with an MPL3115A2 sensor for pressure and temperature readings, and a Neo 6M GPS module for location tracking. The ESP32 is also connected to an SD card reader for data logging purposes. A voltage regulator is used to step down the USB power supply to 3.3V, which powers the ESP32, the sensor, and the SD card reader.

Below is an example of how to blink an LED connected to GPIO2:
// Define the GPIO pin where the LED is connected
#define LED_PIN 2
void setup() {
// Set the LED pin as an output
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// Turn the LED on
digitalWrite(LED_PIN, HIGH);
delay(1000); // Wait for 1 second
// Turn the LED off
digitalWrite(LED_PIN, LOW);
delay(1000); // Wait for 1 second
}
