Moreover 2N3904 also work good as an amplifier.

push({});Where We Can Use it How to Use:2N3904 can be used in any electronic applications which fall under its electrical characteristics. description and other information about this IC.

but the different is in this circuit the variable resistor middle pin is connected with pin 2 or inverting input of section A of the IC as a result the circuit will now make the output of Section A high when there is complete darkness or low light also depends on the adjustments of the 20K variable resistor.LM358 Description: LM358 is an operational amplifier 8 pin IC available in different packages.

An LED is connected at the output pin 1 which is the output of the operational amplifier 1 or Section A.One of the main feature of this IC is its low current consumption that makes it ideal to use with battery operated projects or devices.
