Power: USB-powered, 3.3V or 5V inputCode Examples### Example 1: Blinking an LED using Particle APIThis example demonstrates how to use the Particle Photon to control an LED connected to digital pin 2.```c
// Import the Particle API library
#include <Particle.h>// Define the LED pin
const int ledPin = D2;void setup() {
// Initialize the LED pin as an output
pinMode(ledPin, OUTPUT);
}void loop() {
// Blink the LED
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
```### Example 2: Connecting to Wi-Fi and sending data to the cloudThis example demonstrates how to connect to a Wi-Fi network and send data to the Particle Cloud using the Particle API.```c
// Import the Particle API library
#include <Particle.h>// Set your Wi-Fi credentials
const char wifiSSID = "your_wifi_ssid";
const char wifiPassword = "your_wifi_password";// Set your Particle device ID and access token
const char deviceId = "your_device_id";
const char accessToken = "your_access_token";void setup() {
// Connect to Wi-Fi
WiFi.connect(wifiSSID, wifiPassword);
while (!WiFi.ready()) {
delay(1000);
Serial.println("Connecting to Wi-Fi...");
}
Serial.println("Connected to Wi-Fi");// Connect to the Particle Cloud
Particle.connect();
while (!Particle.connected()) {
delay(1000);
Serial.println("Connecting to Particle Cloud...");
}
Serial.println("Connected to Particle Cloud");
}void loop() {
// Send data to the Particle Cloud
Particle.publish("temperature", "25.0", PRIVATE);
delay(10000); // Send data every 10 seconds
}
```### Example 3: Reading data from a sensor using I2CThis example demonstrates how to use the Particle Photon to read data from a temperature sensor (e.g., TMP102) connected via I2C.```c
// Import the Wire library for I2C communication
#include <Wire.h>// Define the I2C address of the TMP102 sensor
const int tmp102Address = 0x48;void setup() {
// Initialize the I2C interface
Wire.begin();
}void loop() {
// Read temperature data from the TMP102 sensor
Wire.beginTransmission(tmp102Address);
Wire.write(0x00); // Read temperature register
Wire.endTransmission();
Wire.requestFrom(tmp102Address, 2);
int tempData = Wire.read() << 8 | Wire.read();// Convert temperature data to Celsius
float temperature = tempData 0.0625;// Print the temperature value
Serial.print("Temperature: ");
Serial.print(temperature);
Serial.println(" C");delay(1000); // Read temperature every 1 second
}
```These examples demonstrate the versatility of the Particle Photon and its ability to connect to the internet, interact with sensors and actuators, and send data to the cloud.
