The digital Revolution started in 1950 changes all the existing mechanical and analog electronic structures into digital computers. Since the growth of digital electronics has been exponential, today it is almost impossible for a person to resist using any electronic equipment. Starting from the alarm clock that wakes you up and the toaster that serves […]

Hello everyone, Today in this project, we will interface RF Receiver and Transmitter module with PIC Microcontroller and communicate between two different pic microcontrollers wirelessly. In this project we will do following things:- We will use PIC16F877A for the Transmitter and PIC18F4520 for the Receiver section. We will interface Keypad and LCD with PIC microcontroller. On the transmitter side, we
PIC Microcontrollers are a powerful platform provided by microchip for embedded projects; its versatile nature has enabled it to find ways into many applications and is yet to grow a lot. If you have been following our PIC tutorials then you would have noticed we have already covered a wide range of tutorials on PIC microcontroller starting from the

In this project we will interface a Relay with PIC Microcontroller PIC16F877A. Relay is a mechanical device to control high voltage, high current appliances ‘ON’ or ‘OFF’ from lower voltage levels. Relay provides isolation between two voltage levels and it is generally use to control AC appliances. From mechanical to Solid state relays, there are various type of relays are
RFID stands for Radio Frequency Identification. RFID module can read or write small amount of data into a Passive RFID tag, which can be used in identification process in various systems like Attendance system, security system, voting system etc. RFID is very convenient and easy technology. To read the Passive RFID cards and tag, we need a microcontroller with UART
Thermal printer is often referred as receipt printer. It is widely used in restaurants, ATM, shops and many other places where receipts or bill is required. It is a cost-effective solution and very handy to use from the user’s side as well as from the developer’s side. A thermal printer uses a special printing process which
Heart Beat rate is most important parameter in monitoring any person’s health. In the modern era of wearable devices, there are lot of devices which can measure heartbeat, blood pressure, footsteps, calories burnt and lot of other things. These devices has pulse sensor inside them to sense the pulse rate. Today, we will also use
