c program for automatic car parking indicator using microcontroller 8051

This system will indicate empty and filled car parking slots at the entry. Now a days Car parking at shopping malls and markets is becoming a big issue and is causing to traffic jam. To avoid this problem we are designing this system to indicate empty slots and filled slots, so that a car driving person can directly take his car to that particular empty slot. we will indicate the slot state by LEDs and also in LCD screen. we will use IR sensors to sense the presence of c ....etc

battery level indicator project using 8051 microcontroller

Here is a easy to build low battery level indicator circuit that produces a visible indication by flashing a LED when the battery voltage drops below a predetermined voltage.The circuit is based on Panasonic s IC MN13811G and a efficient flasher based on transistors Q1&Q2.Here when the battery voltage drops below 2.4 V the output of the IC is activated and the flasher starts flashing.This circuit here is an ideal one for monitoring the level of all types of 3V batteries.The circuit ....etc

Gate Turn On Turn Off Thyristors


What is a thyristor?

Thyristors are power semiconductor devices used in power electronic circuits

They are operated as bistable switches operating from non-conducting to conducting states.

They are made of 4 layers and 3 pn junctions.

Thyristors are three terminal devices the terminals being anode, cathode and gate.

Working of a thyristor

When anode voltage is positive with respect to cathode j ....etc
