What are some beginner-friendly Arduino sensor tutorials?
There are several great tutorials for beginners! You can start with the temperature sensor tutorial, which uses the DHT11 sensor.
Can you explain how to set up the DHT11 sensor?
Sure! First, connect the DHT11 sensor to your Arduino: VCC to 5V, GND to GND, and the data pin to a digital pin, say pin 2.
What code do I need to upload to read the temperature?
You can use the DHT library. Here's a simple code snippet:
#include <DHT.h>
#define DHTPIN 2
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);
void setup() {
Serial.begin(9600);
dht.begin();
}
void loop() {
float h = dht.readHumidity();
float t = dht.readTemperature();
Serial.print("Humidity: ");
Serial.print(h);
Serial.print("% Temperature: ");
Serial.print(t);
Serial.println("°C");
delay(2000);
}
What other sensors can I use with Arduino?
You can use various sensors like the ultrasonic distance sensor, light sensor, and motion sensor. Each has unique applications!
