+As you may recall from Lesson 1, there are two ways of connecting the LEDs.
-*led cathode connected to Microduino digital I/O port D3 ~ D10, anode connected VCC of Microduino, so that low-level light led.
+*Method One: Connect the negative ends (cathodes) of the LEDs to the GND port of Microduino and connect the positive ends (anodes) to digital I/O ports D3~D10. High level connection.
-In fact, this is the some principle as Nixie tube control of common cathode and common anode, we will give detailed introduction for how derive Nixie tube.
+*Method Two: Connect the cathodes to the digital I/O ports D3~D10 and the anodes to VCC. Low level connection.

-This experiment similar with the 51 microcontroller running water light writing, assign the hexadecimal array values to the I/O port to light the LED. Such as 0x18 is equivalent to binary 00011000, the corresponding value to "1" on, "0" off. You can write all kinds of tricks randomly.
+Comparing the two programs, the first looks simple, has only one pattern, and is very limited.The second program is optimized. Using an array, the hexadecimal number's each bit is assigned to the specified I/O port. Waterfall LED designs can be created using the second program.
