Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

The working principle of this circuit is extremely simple and straight forward. When the infrared proximity sensor (E18-D80NK) senses an object in front, its internal NPN transistor pulls the output ...
