Arduino Photoresistor Tutorial with a Nokia 5110 display @Educ8s

Uploaded October 2014 | Updated September 2026, 3 weeks ago

In this Arduino photoresistor Tutorial, we build a simple and easy light meter. For this, we use a photoresistor a Nokia 5110 LCD display an Arduino Mega. 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. A photoresistor can be applied in light-sensitive detector circuits, and light- and dark-activated switching circuits.
