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 be looking at keypad interfacing with the 8051 microcontroller. In this article, we will discuss the code part as well as the structure of the keypad. We can interface any size keypad with the 8051 microcontroller. Matrix Keypads have applications in calculators, mobile phones, telephones, ATMs, etc. It is useful … Read more
In this article, we will learn how to interface an LCD with an 8051 microcontroller. It is not very hard to interface an LCD with an 8051 microcontroller if you already know how to use KEIL for programming and how to use the input-output ports of the 8051 microcontroller. We can use LCD to display … Read more
In this article, we will learn to interface an analog-to-digital converter (ADC 0804) with an 8051 microcontroller. Unlike the PIC, Arduino, and AVR microcontrollers, the 8051 microcontroller does not have a built-in ADC. If we want to interface any sensor with the 8051 microcontroller which provides analog output, we have to use an external ADC. … 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
