How do I set up sensors with Arduino?

To set up sensors with Arduino, you'll need to connect the sensor to the Arduino board and write a code to read the sensor data.

What type of sensors can I use with Arduino?

You can use various sensors like temperature sensors, humidity sensors, motion sensors, and light sensors.

Can you give me an example code for a temperature sensor?

Sure! Here's a simple example using the DHT11 temperature sensor:

#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");
}

What if I want to connect multiple sensors?

You can connect multiple sensors by using different pins for each sensor and modifying your code to read from each one accordingly.
