Welcome to CIRCUIT EASY Mini Projects. Easy to make basic Electronics Projects using simple circuit diagram for Student, Hobbyist and Educationist. All are DIY (Do it yourself) and EFY Projects for School.

Experiment using Sensor:


Clap Switch : Classical project for turning ON/OFF appliances by a sound of clap.


Automatic Street Light : Needs no manual operation for switching ON and OFF.


Electronic Letter Box : When letter is present inside then LED glows.


Simple LDR Circuit : Make a light activated switch using single transistor.


Rain Alarm : We get a tone when wire is in contact with water so this circuit can also work for tank overflow indicator.


Heat Sensor : Simple, but sensitive Circuit for indication of temperature using thermistor.


Temperature Sensor : For Detection of  Accurate Degree Centigrade by which you can make  many interesting projects.


Temperature Display using LCD : Digital Display Current Temperature using Arduino Microprocessor and simple 2X16 Character LCD.


Automatic Fan Controller : Fan automatically starts rotating when temperature is hot and also speed is controlled according to the temperature. Easy Mini Projects.


Electronic Eye : It can be used as an automatic guest indicator if fitted on the bottom of the door entrance so there is no need to install a call bell. It can also be used at homes or in banks as a burglar alarm.


Burglar Alarm : We kept LDR in such a place that when thief enters our house, a shadow will fall on it.


Touch Switch : When any one touches sensor then we get a tone.


Fire Alarm : Simple Circuit for detection of fire. Simple and Mini


Magnetic Switch : Learn how magnetic field can be used to switch on circuit.
