CHAPTER 1 INTRODUCTION 1.1 Background of the Project LED blinking project can be used as attraction. This project was done with PIC16877A. The LED will blinking on delay timer which make the LED look like running. 1.2 Problem Statement The circuit need to off manually or need to cut the voltage to stop the blink. By using the magnetic switch the circuit can off by giving input to the PIC. 1.3 Objective The objective of this project

hardware circuitry (PCB etc.) and software development for the Electric Escape lock which has selfactivated mechanism and access control system. The PCB design was created from the specifics of the physical lock unit using Altium designer. The microcontroller was programmed using C programming language in MPLABX. The complete system operates successfully and performs selfactivation and automatic operation of 3 seconds delay. The current development is enriched up to version 1 level with provision

KEYPAD & SENSOR IN PIC MICROCONTROLLER. A 4X4 matrix keypad is useful for the function like a simple calculator or telephone. The 4X4 keypad has 16 keys which are arranged in push button switches in rows and columns. This keypad is followed by two other components‚ the 16-key encoder and the sensor pad. As you can see below is the diagram on a simple 4X4 matrix keypad. This requires users to key in numbers in decimals or hexadecimals depending on the encoder that is programmed to the 4X4

the load will be connected to the particular live phase only. Even a single phase is available‚ and then also‚ the load will be in ON condition. The aim of this project is to construct a single phasing monitor and prevention system using 8bit microcontroller. Anti-single phasing relays or single phasing preventer are required for critical loads and circuits. These are required because the normal overload protection doesn’t trip on time. For large air-conditioning compressors‚ irrigation pumps these
