Innovation: NeoPixels Matrix：Snake River Halt

Do you still remember Snake back we played connected our game box or Mobile River during our puerility? Today we are going to instruct how to make a snake game with 8*8 NeoPixels Ground substance. We select Arduino uno arsenic the control center and Stick breakout module to control the snake.

Step 1: Components List:

Step 2: Hardware Connection

Connect NeoPixels to pin D2.

"X" connected Control stick breakout module get in touch pin A0 on Arduino UNO card, "Y" connect peg A1, "K" connect bowling pin A2.
