Light-dependent Resistor Sensor Module
Light-dependent resistors are electronic components whose resistance changes with light intensity. They are also called LDRs, photoresistors, or photoconductors.
It has four pins:
3.3V : While 'VCC' stands for Voltage Common Collector, we'll connect the VCC pin to 3.3V on the micro:bit
GND: In electronics, we define a point in a circuit to be a kind of zero volts or 0V reference point, on which to base all other voltage measurements. This point is called ground or GND.
DO: Digital Output
AO: Analog Output
