==Outline==
*Project：Microduino Snake Game
*Objective：Connect the mobile and Microduino-Core by Microduino BT module，then control the double color LED lattice to play snake game!
*Difficulty：High
*Time-consuming：4 hours
*Maker：Microduino Studio-YLB

First solution:

*Step 1：Prepare the experiment equipment

*Step2：Build adapter board
**Cut a certain specification size pegboard；
**Weld the row needles；

**After finished weldign, use the bread board to make connection, From left to right in turn is the SDA and SCL, GND, VCC.；

*Step 3：Change the lattice, because the original LED lattice doesn't easy to connect the jumper, so change its row needles match Microduino's pin.

*Step 4：Stack the module and lattice, measure the shell size.

*Step 5：Draw the 3D shell

*Step 6：Print 3D shell

*Step 7：Assembly, put all module into 3D shell

*Step 8：Software debug
**Download the library and test program
**Select the board and serial to download after compiled it. Note, program use softwareSerial to debug, SoftwareSerial mySerial(9, 10). So need change the serial pin to D9,D10 on Microduino BT module, or change the code.
**Turn on the mobile BLE and APP, connect the Microduino and mobile, and then start to control.

==Result==
Boot into the game after rolling Microduino, snake color is green, fruit is red. Because of the lattice is very small, won't increase the snake length, instead to increase the speed, and keep a certain high speed. When the snake hit the walls, show "GAMGOVER" and your scores, then restart again.

==The issue need pay attention==
*Bread board jumper connection between pegboard and Microduino should be correct；
*The serial communication pin between MIcroduino BT and Microduino Core can't make a mistake.

Second solution：
Use Microduino double color lattice.
==Advantage==
*Square LED lights, very beautiful
*Microduino standard board, stack it directly
*Microduino double color lattice's size is 60*60mm, Visual effect is better.

**Turn on the mobile BLE and APP, connect the Microduino and mobile, then start to control.
**If connect success, Microduino BT indictor doesn't blink.
