Interfacing LED: Chasing LED (LED chaser)

 CHASING LEDs                   

In this project  8 LEDS are connected to PORTC of PIC 18F452 microcontroller and
the microcontroller is operated from a 4MHz resonator. The program turns on the
LEDs in a sequencial manner with a 1 second delay between each input. The net
result is that the LEDs seems to be chasing each other.

Intermediate switch connection and wiring diagram

Intermediate switch An intermediate switch is a switch which permits the control of a lighting point from three positions. In order to control this lighting point from the three positions, the intermediate switch is connected together with two other 2-way switches. Application: it can be used in lighting a room or hall having 3 entrances , it can also be used in long corridors and staircases. We shall be looking at these connections. Connection diagram of intermediate switching Below is an illustration of the connection. The brown lines indicated on the diagram are the switching contacts. The switch labelled 2 is an intermediate switch . The figure below is the configuration of an intermediate switch. The switch labelled 1 and 3 in the first diagram are two-way switches.  Click here to know more about two-way switches . ON and OFF positions of intermediate switching ON positions OFF positions Staircase wiring layout using an inte...

Differences between ELCB and RCCB, MCB and MCCB

ELCB AND RCCB (RCD) Earth Leakage Circuit Breaker (ELCB) Working Principle of ELCB An Earth Leakage Circuit Breaker (ELCB) is a security device used in an electrical installation to detect leakage current and protect humans against the risk of an electric shock, from this leakage current. The operation is such that, the power supply connected at its switching terminal (contact of the circuit breaker) is disconnected by a special type of latching relay when it detects a leakage current. Thereby, protecting individuals getting in contact with this leakage current against the risk of an electric shock. This circuit breaker remains OFF until reset manually. Types of Earth Leakage Circuit Breaker They are two types of Earth Leakage Circuit Breakers. They are named based on their principle of operation. They are; The Voltage Earth Leakage Device (Known as the ELCB) and The Current Earth Leakage Circuit Breaker (RCD or RCCB). In the past, when referring to Earth Lea...
