In this blog post, we learn how to build calculator using PIC Microcontroller. Calculator with PIC Microcontroller(16f877A ) is a complicated project. Complicated in the way that code is lengthy and logical. Here I assumed you already know how to interface LCD  and Keypad with PIC Microcontroller. But if you don’t know how to interface […]

In this blog post, we will learn 4×4 keypad interfacing with PIC Microcontroller. A keypad interfacing with PIC Microcontrollers is interesting. A keypad is an organized matrix of switches in rows and columns and it comes in the various form like a numeric keypad, alphanumeric keypad. It also comes in different sizes like 4×3, 4×4,

In this blog post, we will learn 4 bit LCD interfacing with PIC Microcontroller (PIC16F877A). In my previous blog post, we discussed “how to interface 16×2 LCD with PIC Microcontroller (PIC16F877A) in an 8-bit Mode“. Here I assume that you already know how to interface LCD in 8-bit mode. Here we will also see the

In this blog post, we will learn how to interface 16*2 Alphanumeric LCD with PIC Microcontroller (PIC16F877A) in an 8-bit Mode. We will also see the circuit diagram of  LCD 8-bit interfacing with PIC Microcontroller. Nowadays alphanumeric LCD is used in many devices to display the message, like printer, coffee machine, remote, etc. Alphanumeric LCD

In the article, we will learn push button interfacing with PIC Microcontroller. Like another Microcontroller PIC also provide the GPIO (General Purpose input-output) pins. We can interface input-output devices (Led, Switch, Adc, Sensors, ..etc)  to GPIO pins. Here we learn how to control a led using an SPST (single pole single throw) switch. An Led

In the article, we will learn led interfacing with PIC Microcontroller. Like another microcontroller PIC also provide the GPIO (General Purpose input-output) pins. We can interface input-output devices to GPIO pins. The LED interfacing with PIC Microcontroller program is very sample.  If you want to toggle the led blinking then you need to toggle the

In the article, we will see how to read and write the internal EEPROM of PIC Microcontrollers. Generally, PIC microcontrollers come with some built-in EEPROM which is used to store data permanently. An EEPROM is a non-volatile memory that means it can store the data permanently without any power supply. EEPROM stands for Electrically Erasable

In the article, we see the interfacing  EEPROM with PIC Microcontrollers using the I2C Protocol. In the real world, microcontrollers have a limited amount of memory. Sometimes the limited amount of memory becomes a big issue and creates a roadblock to the development of a project. Each microcontroller provides flexibility to connect an external memory to

In this blog post, we will learn how to interface RTC DS1307 with PIC Microcontroller (PIC16F877A).  RTC DS1307 connects with PIC  Microcontroller using the I2C protocol. So here we will also see the I2C protocol implementation for PIC  Microcontroller with the interfacing of 16X2 LCD. You can see the below articles, Understanding of I2C protocol.
