Hello friends, I hope you all are doing great. Today, I am going to share our new LDR Sensor Library for Proteus . An LDR (light dependent resistor, also called a photoresistor) is the simplest light sensor there is: its resistance drops when more light falls on it.

Hello friends, I hope you all are doing great. Today, I am going to share the new Sound Sensor Library for Proteus V3.0 . The KY-038 is the small blue sound sensor module with a microphone, a sensitivity pot and an LM393 comparator. Its A0 output carries the microphone's sound wave, and its D0 output pulses when a sound is loud enough. With this Sound Sensor Library for Proteus , you pick the sound, its distance and the pot, and your Arduino reads A0 and D0 exactly as it would on a real board.

Hello friends, I hope you all are doing great. Today, I am going to share the new Infrared Sensor Library for Proteus V2.0 . It simulates the FC-51 IR obstacle sensor , the small blue board with a clear IR LED and a dark photodiode at one end, which tells your Arduino with a single pin whether something is in front of it. With this Infrared Sensor Library for Proteus , you place the object yourself (its distance, its colour, indoor light or sunlight, even a waving hand), and your Arduino reads the OUT pin exactly as it reads the real module.

Hello friends, I hope you all are doing great. Today, I am going to share the new Gas Sensor Library for Proteus V2.0 . It simulates the popular MQ-2 gas sensor module : the MQ-2 sensor in its steel mesh cap on the small blue board with the LM393 comparator. With this Gas Sensor Library for Proteus , you fill a little kitchen with LPG, smoke, alcohol, methane or hydrogen, and your Arduino reads the MQ-2's analog output A0 and its digital output D0, just like on a real board.

Hello friends, I hope you all are doing great. Today, I am going to share the new Flame Sensor Library for Proteus V2.0 . The flame sensor is the small blue module with a black infrared receiver on long legs: it sees the infrared light of a flame and tells your Arduino about it through an analog output (A0) and a digital output (D0). With this Flame Sensor Library for Proteus , you light a candle, a lighter or a gas burner in the simulation, move it closer or turn the sensor away, switch on the sun, and your Arduino reads the module just as it reads a real one, with analogRead() and digitalRead() .

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide you the discussion on Introduction to LM393. LM-393 has two internal operational amplifiers. These are internally frequency compensated. These are specifically designed to perform their tasks using a single power supply sources. LM-393 can also perform its operations properly by using split power supply. The current drain supply does not depend upon the magnitude of the power supply. One of the most amazing feature of LM 393 is that ground is included in its common mode input voltage. Moreover, LM 393 has a lot of features e.g. wide voltage supply ranges, a very small current drain supply, low input offset current, low input bias current, output voltage compatible with Transistor Transistor ...
