Description
4-Digit LED Module! There are four pins:
Clock Input (CLK)
Input/Output Serial Data (DIO)
3.3V Β : '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 Β ground or GND.
Voltage is the difference in potential between two points. As it is difficult to talk about voltage without a reference point, we need another point to compare it to.
