utilize a microcontroller's GPIO pins to control peripheral devices in an IoT embedded software in C

Hello guys how can i utilize a microcontroller's GPIO pins to control peripheral devices in an IoT embedded software in C or Arduino, I want to control a LED by turning it on or off using a GPIO pin, can I be provided some general steps or considerations for using a GPIO pin to interact with peripheral devices in an IoT application. also, are there any specific libraries that can help me get started @Middleware & OS

Solution:

You can use the following libraries Arduino Standard Library ESP8266/ESP32 Libraries FreeRTOS: For more advanced IoT applications requiring real-time capabilities, consider using FreeRTOS, which is available for several microcontrollers including STM32 and ESP32....

This example is for Arduino, Connect the LED: - Connect the LED's anode (long leg) to Arduino Uno's digital pin 13 - Connect the LED's cathode (short leg) to the ground (GND) pin on the Arduino Arduino Code:

void setup() {
  pinMode(13, OUTPUT); // Initialize pin 13 as output
}

void loop() {
  digitalWrite(13, HIGH); // Turn on the LED
  delay(1000); // Wait 1 second
  digitalWrite(13, LOW); // Turn off the LED
  delay(1000); // Wait 1 second
}

void setup() {
  pinMode(13, OUTPUT); // Initialize pin 13 as output
}

void loop() {
  digitalWrite(13, HIGH); // Turn on the LED
  delay(1000); // Wait 1 second
  digitalWrite(13, LOW); // Turn off the LED
  delay(1000); // Wait 1 second
}

- Pin 13 is set as output using pinMode() - digitalWrite() is used to set the pin high (turn on the LED) or low (turn off the LED) - delay() is used to create a 1-second interval between on and off states You can also use any digital pin of your choice
