This project is a simple test of a photoresistor’s functionality: we’ll create a night light that gets brighter depending on the amount of light detected.
HOW IT WORKS
A photoresistor is a variable resistor that reacts to light; the less light that shines on it, the higher the resistance it provides. This resistance value varies the voltage that’s sent to the input pin of the Arduino, which in turn sends that voltage value to the ...
