How to MAKE a DARK SENSOR with LDR Easily

How to MAKE a DARKNESS SENSOR with LDR Easily In this video tutorial of easy electronic projects we will see how to make a darkness sensor with LDR at home, it is very useful if what we want is for a light to turn on when the power goes out, let's do use of the electronic diagram to see how it is done easily and we are going to use a 2n2222a transistor that we can buy at the electronics store or recycle it from an electronic device that is no longer used, a led diode that we can recycle or buy, a 470 ohm electrical resistor, an LDR or resistor that depends on light, a 100k potentiometer, a 9v battery or battery, recycled electrical cables from an electronic device for connection, and a PROTOBOARD to assemble all the electronic circuit and at the end of the video we are going to do a series of tests to see how the electronic project works, if we see that the electronic project works correctly we can assemble it properly rmite in a perforated PCB soldering the components with tin and tinner or soldering iron, if you like the video don't forget to leave your like thanks..
