A photoresistor (or light-dependent resistor, LDR, or photocell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity.…

In this example we connect an LDR to an analog pin of our Chipkit Uno32, depending on the reading we will then vary how bright an LED will be lit…

In this example we will connect an LDR again but this time when the ADC value goes below a certain number we will switch an LED on, in real life…

In this example we connect an LDR to ADC channel 2 which is PA 2. Once again you will get a value in theory between 0 and 1023. The more…

In this example we show how you connect a photoresistor to an Arduino, the value read from the photoresistor corresponds to the amount of light present. The photoresistor is connected…
