How to call function to read temp and read light .

int lightPin = A1; // Analog input pin for light sensor

int tempPin = A2; // Analog input pin for temperature sensor

void setup() {

Serial.begin(9600); // serial communication at 9600 bits per second

}

void loop() {

if (Serial.available()) {

String command = Serial.readStringUntil(' '); // Read the incoming command from serial monitor

if (command == "Read Temp") { // If the command is to read temperature

float temp = (5.0 * analogRead(tempPin) * 100.0) / 1024.0; // Calculate the temperature in Celsius

Serial.print("Temperature is: ");

Serial.print(temp);

Serial.println("C");

}

else if (command == "Read Light") { // If the command is to read light intensity

int lightValue = analogRead(lightPin); // Read the analog value from the photoresistor

Serial.print("Light intensity is: ");

Serial.println(lightValue);

}

else if (command == "Read all sensors") { // If the command is to read all sensors

float temp = (5.0 * analogRead(tempPin) * 100.0) / 1024.0; // Check if this correct

int lightValue = analogRead(lightPin); // Read the analog value from LDR

Serial.print("Temperature : ");

Serial.print(temp);

Serial.println("C");

Serial.print("Light intensity : ");

Serial.println(lightValue);

}

else { // If the command is not recognized

Serial.println("Invalid command.");

}

}
