Array and pointer have a close relationship but both are different concepts in C programming. In this blog post, I will discuss the difference between pointer and array ( pointer vs array ). Before going to see the difference between pointer and array let us see the introduction of the array and pointer. If you

In this blog post, we will learn how to interface 16×2 Lcd with PIC Microcontroller (PIC16F877A). We will also learn how to display custom characters on 16X2 LCD using PIC microcontroller. 16X2 LCD has a controller HD44780, which provides the 8 locations (CGRAM ) to store the created LCD custom characters. We can use these

In this article, I will explain how you can make a water level controller using 8051 microcontroller. The water level controller saves the energy and it controls the water motor by sensing the water level in the tank. Below I am mentioning a small code for 8051 microcontroller which controls the water level and blinks

It is very interesting to learn how to interface the ADC with the 8051 microcontroller. Like another microcontroller (PIC, Arduino Avr microcontroller ..etc) 8051 microcontroller does not have built-in ADC. So if you want to use LM35 temperature sensor to measure temperature with 8051 then you have to interface external ADC with 8051 microcontrollers. In

Nowadays there are a lot of devices that use the serial interface for data transmission. When I am talking about the serial interface then there are a lot of serial interfaces are available like I2C, SPI, USB and many more. But the two oldest serial interfaces RS232 and Rs475 are still alive and used by
