Temperature display using LCD

Here is a Simple Temperature Display Circuit using LCD (Liquid Crystal Display). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree, then Read more…

Solar Cell

How Solar System Works? Learn by Animation The circuit illustrated here is used as Solar Cell. You can get plate from your old faulty solar calculator. Carefully dissemble plate with out tearing its 2 wire. Connect both wire to a LED through a switch. When Solar Plate is kept in Read more…

Robot Circuit

Microprocessor is essential for all types of Robotics Project As you know our site is based on Simple Electronics Project Circuit.  To achieve higher performance, (Engineering Level Project) you have to use Microprocessor, which is commonly used now day’s in most electronics gadget. i.e remote control circuit,UPS, TV circuit, Mobile, Read more…

Rectifier

LESSON ON HALF WAVE RECTIFIER / FULL WAVE RECTIFIER / BRIDGE RECTIFIER A Rectifier converts  AC (Alternating Current) in to DC (Direct Current ). Generally Diode is used as rectifier.  Rectifier uses the property of Diode( semi-conductor device)   to allow flow of current in only one direction.         Read more…

Rain Alarm

GIVES BEEP WHEN WATER IS IN CONTACT WITH THE WIRE Rain Alarm Project Here is an interesting electronics project to detect if there is raining or not. Same circuit can also be used as water level indicator or as a tank overflow indicator. Working: Water is a conductor of electricity. Read more…

NOR Gate

NOR Gate is combination of OR Gate whose output is followed by a NOT Gate. Below is the picture of our experiment conducted. In this project OR gate is constructed using two Diodes. Input level for each diode is fed by two individual switches. Here NOT Gate circuit is made Read more…

NAND Gate

In this NAND Gate circuit I have used three Transistors. In this Project NAND gate is made by combining AND and NOT Gate. Here first two transistor in series is used for making AND gate and the last transistor which is parallel with LED makes NOT Gate. Both is connected Read more…

Logic Gates

Logic gates are the building blocks of digital technology. It is a mechanical, optical, or electronic system that performs a logical operation on an input signal. Truth tables are used to help, show the function of a logic gate. Simple Logic Processor Circuit or you can say a simple computer.       Read more…
