How do I code a sensor with Arduino?

To code a sensor with Arduino, you'll need to connect the sensor to the board and use the appropriate library. What type of sensor are you using?

I'm using a temperature sensor.

Great! For a temperature sensor like the DHT11, you can use the DHT library. First, install the library, then use the following code snippet to read the temperature.

Can you provide the code snippet?

Sure! Here's a simple example:

#include <DHT.h>

#define DHTPIN 2     // Pin where the sensor is connected
#define DHTTYPE DHT11   // DHT 11

DHT dht(DHTPIN, DHTTYPE);

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

void loop() {
  delay(2000);
  float t = dht.readTemperature();
  Serial.print("Temperature: ");
  Serial.println(t);
}

Thanks! How do I display the temperature on an LCD?

You can use the LiquidCrystal library to display the temperature on an LCD. Would you like a code example for that?
