In this tutorial, we will see the serial communication programming of the 8051 microcontroller. When electronic devices communicate with each other, they can transfer data in two different ways. One way of communicating is serial, and the other is parallel. When we transfer digital data in serial mode, this mode transmits the data bit by … Read more
In this tutorial, we will discuss servo motor interfacing with the 8051 Microcontroller. The uses of servo motors are in robotics, embedded systems, and other industries because they are very precise and reliable. Their applications also include operating remote-controlled toy cars, airplanes, or robots. We can control their motion by rotating them at a particular … Read more
In this tutorial, we will discuss stepper motor interfacing with the 8051 microcontroller. Stepper motors are types of DC motors with multiple electromagnetic coils. We call the arrangement of these coils in group as phases. Motors rotate when we provide energy for a particular phase. One step of rotation occurs at a time by energizing a … Read more
In this tutorial, we will learn about DC motor interfacing with an 8051 microcontroller. In many embedded system projects, we may need to control a DC motor using a microcontroller. It is not a good practice to connect the DC motor directly to the microcontroller, as it may damage the microcontroller. For this, we use a … Read more
In this tutorial, we will discuss how to use GPIO interrupts which are also known as external interrupts of 8051 microcontroller. We will learn to configure GPIO interrupts as edge-triggered such as positive or negative edge or level triggered such as active high or active low level triggered. Before reading this article, you should know … Read more
In this tutorial, we will learn how to use timers on the 8051 microcontroller to generate a delay. The 8051 microcontroller has two 16-bit built-in timers. We can program each timer individually and configure them as either timers (to generate time delays) or counters (to count events occurring outside the microcontroller). The 8051 timer has … Read more
In this tutorial, we will learn how to use the input and output ports of the 8051 microcontroller. The 8051 microcontroller has 40 pins, comprising four I/O ports. The microcontroller uses 8 pins for specific purposes, while 32 pins are configurable as input and output pins to connect the microcontroller with peripheral devices. Each port … Read more
In this article, we will learn to setup KEIL IDE to program the 8051 microcontroller. Hobbyists and developers use Atmel 8051 microcontrollers in IOT projects. These microcontrollers require KEIL IDE software for their programming. The program can be written in C or assembly language. Now we will discuss how to write the first program in … Read more
This article will teach you how to interface a microcontroller with an optocoupler. How can you interface AVR, PIC, and 8051 microcontrollers with an optocoupler? What exactly is an optocoupler? What are the fundamental principles of an optocoupler? Power electronics projects, such as firing angle control circuits and AC power control circuits, often rely on … Read more
