I need working of dark sensor using LDR and LM324 ,no transister used.

The LM324 is a 14 Pin dual in-line Plastic Package chip which has four independent, high-gain, internally frequency compensated operational amplifiers (Op-Amp) designed to operate from a single power source. It is also possible to power this with 4 different power sources….One for each independent Op-Amp inside the chip. This chip can be used as a Power Amplifier , LED Driver , “BI-QUAD” RC Active Bandpass Filter , Lamp Driver , Pulse Generator , Square wave Oscil ....etc

Non Conventional Energy System




Throughout the history of human kind, energy has been an important factor is development. The availability and exploitation of new energy sources has made possible major economic and social changes. Modern societies requiring a large amount of energy used in agricultural, industrial and transport uses. Energy sources can be classified as commercial energy sources and non-commercial energy sources. Commercial sources includes fossil fuels (coal, oil, Naturalgas) while non-commercial energy sources includes ....etc

Chapter I
INTRODUCTION
i.Background
The path of exploring the final year project had many barriers, but it made us imbibe some valuable knowledge of the field. We started searching project from internet and various magazines. We saw a number of projects from EFY and CHIP Magazine. We came across many projects on DC motor control, tachometer and RPM meters; but all these projects seemed to be very common, so using this concept we thought to have the idea of counting the RPM of any motor and we discussed this topic with our ....etc
