As soon as the shadow falls on it, the resistance of the device begins to increase. The main use of the LDR is to sense the presence of a person through his shadow falling on the sensor. In this circuit, apart from the 741 op-amp IC, a Light Dependent Resistor (LDR) is also used. We have given a very detailed description and circuit diagram for every one of the. Most of them are simple and easy to make a home. Given below are some links to some of the best op-amp based circuits designed by us. The different pin assignments of the 741 IC are also explained with neat figures. The article also contains information about the 741 IC, its packaging style, the use of op-amp as an inverting and non-inverting circuit, and so on. The different advantages of op-amps are also specified, along with links to different basic op-amp circuits like Comparator Circuit, Schmitt Trigger Circuit, Astable Multivibrator, Monostable Multivibrator, Zero-crossing detector, voltage splitter and so on. The above linked article contains all the basics of op-amps, with the basic op-amp circuit with two transistors.
To learn about it click on the link – Operational Amplifiers (Op-amps) We have classified this list into three parts:-īefore going into detail about the different op-amp application circuits, it is important to know about the basics of op-amp, and the small applications of the IC.
