Light-dependent Resistor with micro:bit

Before we begin, let's take a closer look at the light-dependent resistor module. 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
