What is the purpose of the 'setup()' function in ESP32 programming?

• To handle user input during runtime.

• To initialize the program and set up the environment.

• To define the main loop of the program.

• To manage power consumption settings.

How do you connect the ESP32 to a Wi-Fi network?

• Use WiFi.begin(SSID, PASSWORD) to connect the ESP32 to a Wi-Fi network.

• Invoke WiFi.link(SSID, PASSWORD) to access the Wi-Fi network.

• Use WiFi.connect(SSID, PASSWORD) to join a Wi-Fi network.

• Call WiFi.start(SSID, PASSWORD) to establish a connection.

What library is commonly used for handling Wi-Fi connections on ESP32?

• Ethernet

• Bluetooth

• Zigbee

• WiFi

What is the function of the 'loop()' method in an ESP32 sketch?

• The 'loop()' method executes code continuously after 'setup()'.

• The 'loop()' method is used to define the main function of the program.

• The 'loop()' method initializes variables before 'setup()'.

• The 'loop()' method runs only once after the 'setup()' method.

How can you read digital input from a pin on the ESP32?

• Use pinMode(pin, INPUT) to set the pin as input and digitalRead(pin) to read the value.

• Set the pin as input using pinMode(pin, INPUT_PULLUP) and use analogRead(pin) to read the value.

• Use digitalWrite(pin, HIGH) to read the value from the pin.

• Use pinMode(pin, OUTPUT) to set the pin as output and digitalWrite(pin, value) to read the value.

What is the maximum number of GPIO pins available on the ESP32?

• 30

• 20

• 25

• 40

How do you define a pin as an output in ESP32 programming?

• pinMode(pinNumber, HIGH);

• pinMode(pinNumber, OUTPUT);

• configurePin(pinNumber, OUTPUT);

• setPinMode(pinNumber, OUTPUT);
