EM-18 RFID reader module is the most commonly used module for radio-frequency identification projects. It offers low cost, small size, low power consumption and easy to use. It can be directly connected to micro-controllers using UART communication. UART software can be used for micro-controllers that do not have UART modules. In this tutorial we will see how to connect the RFID reader module EM-18 with the micro-controller PIC 16F877A. By understanding the basic idea, you will be able to interface with any micro-controller.

pic16f877a based gsm notice board code

Our project is nothing but a GSM based notice board using PIC that is capable of displaying SMS received by it. You can specify what content that you would like to display on the noticeboard by the SMS. The main component of the GSM Notice board is PIC16F877A, received message is displayed on the LCD display which will update automatically when next SMS is received, it has audio indicator to inform that SMS is received. This is an intelligent noticeboard intended as electronics engineering projects for fi ....etc

obstacle avoiding robot using pic16f877a code

One of the biggest challenges in building your own robot is controlling its motors. You can find new or surplus
motors and gearboxes in many places, and low-cost microcontrollers and books on how to use them abound.
However, microcontrollers cannot directly drive DC motors, leaving robotics beginners with the possibly
overwhelming challenge of building their own motor controller. This task is even more complicated if the motors
require bidirectional operation and speed control. This project demonst ....etc

GSM based Control System by pic microcontroller implements the emerging applications of the GSM Technology. Using GSM networks, a control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals.

Remotely the system allows the user to effectively monitor and control the house Appliances and equipment s via the mobile phone set by sending commands in the form of SMS messages and receiving the appliances status. The main concept b ....etc

This Standalone Hardware device (Computer not required) will ring COLLEGE bell at pre-scheduled times of day (all periods) on each day, of the week. Typically, COM time switch can be used to ring COLLEGE bells. It can also be used for other applications where you want a sound to play at preset times. The Device is for colleges, Educational Institutions, Industries and other business where the Bell timer plays a critical role in running the day. The device shows the real time clock during normal operation and a beep announces each bell. Differen ....etc

pic16f877a code for heart rate measurement

Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. This project describes a technique of measuring the heart rate through a fingertip using a PIC microcontroller. While the heart is beating, it is actually pumping blood throughout the body, and that makes the blood volume inside the finger artery to change too. This fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can ....etc
