Snake game is a classic puzzle game. This kit even simulates the Snake game.
The game has 5 levels, each level of speed is different, the higher the level, the faster the speed. Players can control the direction of the snake forward by four keys:’Up’,’Down’,’Left’,’Right’. When the length of the snake reaches 20 dots, it automatically enters the next level.
If snake meets the wall or meets his body, the buzzer sounds and the game starts again. Enjoy yourself!!!!

Installation Attention:
1>. Need to distinguish positive and negative components: LED lights, IN4007 diodes, electrolytic capacitors, buzzer, battery box.
2>. Two kinds of audion to be separated; there are 8 of S8050 ; only one of S8550 , which can not mix.
3>. The RP1 block should be noted for the common port. The first pin is the common port and the square pad on the circuit board.
4>. U1 is a sub unit of a microcontroller. It is soldered to the circuit board SCM inserted into the sub. The notch mark on the circuit board is corresponding to the element and the single chip microcomputer.
5>. The dot matrix screen has digital labels with one port soldered to one port of the pad near the microcontroller
6>. Note that the C5 is an electrolytic capacitor with positive and negative polarity.
7>. There is no component on the circuit board to mark the P1. The blank will do.
8>. On the circuit board D1-D5, the 5 pads on the square pad is positive, corresponding to the components of the positive electrode.
