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

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:
- 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 choiceSolution
