Electronics project

The presented circuit is used to make an electric changer. Many colorful bulbo can be added together with this changer.  This project can be used for decoration on any function or festival.  This project is very simple, durable and very low cost.  This circuit can be made very easily. This circuit is constructed using two NPN transistor BC 548.  And to reduce or decrease the running speed of the light, a variable registers of 22k ohm have been used in this circuit. And used a diode 1N4007 to protect this circuit.  list of all the electronic components used in this circuit is given below.

The project is used to protect electrical equipment from over hits. By using this product, transformers, electric motors and other electrical equipment can be saved from burning due to over hits.  The project presented is designed using two ic LM35 and LM358. The ic LM35 has been used as a digital output temperature sensor. A 10k ohm variable resistor is used in this circuit to set at a suitable temperature.   As the temperature of ic LM 35 increases, plus voltage is started on its output pin number 2.  And its pin number 2 ic is connected to pin number 3 of LM358. Hence ic LM358 comes in on condition. And its output pin number one starts getting plus voltage. And pin number 1 of ic is connected to the base of transistor BC548. Therefore, the plus boltage reaches the base of the transistor. And transistor BC548 turns on. This causes the relay connected to the transistor, to comes normall
