In this tutorial, we will learn to use the GPIO pins of STM32 Nucleo board as digital input pins. In the last tutorial, we have seen how to use GPIO pins as digital output pins. For demonstration, we will also show how to interface a push button with the STM32 Nuclro and read the state … Read more
In this tutorial, we will learn how to use GPIO pins of ESP8266 NodeMCU module as output pins as well as input pins. Accordingly, we will also show how to interface an LED controlled via a push button with the ESP8266 board. We will be reading the value from the Push Button and lighting up … Read more
In this tutorial, we will learn how to use GPIO pins of Pic microcontroller. We will see how to configure general purpose pins either as a digital input and digital output. For demonstration, we will use PIC18F452 microcontroller but you can also any other Microchip microcontroller also. Recommended Components The following components are used in … Read more
