Arduino Light Sensor | Arduino Tutorial

Arduino Light Sensor. Arduino Uno''s pin A0 to A5 can work as the analog input. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value.. By connecting a pin of the photoresistor to an analog input pin, we can read the analog value from the pin by using analogRead() function, and then we can know the light ...


Servomotor con Arduino tutorial de programación paso a paso
