How do I connect sensors to my Arduino?

To connect sensors to your Arduino, you'll need to identify the type of sensor and its pin configuration. What sensor are you using?

I'm using a temperature sensor, specifically the DHT11.

Great choice! The DHT11 has three pins: VCC, GND, and DATA. Connect VCC to 5V on the Arduino, GND to ground, and DATA to a digital pin, like pin 2.

Do I need any libraries to read data from the DHT11?

Yes, you'll need the DHT library. You can install it via the Library Manager in the Arduino IDE. Would you like help with the code?

Yes, please! Can you provide a simple code example?

Sure! Here's a basic example:

#include <DHT.h>

#define DHTPIN 2
#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

void setup() {
  Serial.begin(9600);
  dht.begin();
}

void loop() {
  delay(2000);
  float h = dht.readHumidity();
  float t = dht.readTemperature();
  Serial.print("Humidity: ");
  Serial.print(h);
  Serial.print("%  Temperature: ");
  Serial.print(t);
  Serial.println("°C");
}

This will read and print the temperature and humidity every 2 seconds.
