==Objective==
This tutorial will teach you display a changeing smiling face based on the static one.

==Equipment==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''
*Other hardware equipment
**Breadboard Jumper one box
**Breadboard one piece
**8*8 lattice one
**74HC595 Two
**USB cable one

'''8*8 lattice LED is：LD-1088BS, the following is its pin definition：'''

Define two expression in rows[2][8].

==Debug==
Step 1：Copy the code to IDE and compile it

Step 2：Set up circuit, as follows：
[[File:第三十课-Microduino8_8点阵动作表情连接图.jpg|600px|center|thumb]]
In order to protect the circuit, plus a 220Ω registor on the every connection line (total 8 lines) between one 74HC595 chip and 8*8 latteice LED. In our example, we don't use the registor, so the LED's brightnees is strong. If the lattice's quality is bad and easily broken.

Step 3：Run program

==Result==
The expression will be changed on 8*8 8*8 lattice LED
