};

Hardware Setup

Step1: Connect the three touch buttons to pin 6, 8 and 12 of Hub respectively.

Step2: Connect the two horns to AudioPro.
Step3: Stack AudioPro, Hub, Core+ and Led Matrix together.

How to Play

The touch buttons connected to pin 6, 8 and 12 of Hub stand for A, B and C respectively. When the device is powered, you can select a mode with the touch buttons.

• A corresponds to mode 0;
• B corresponds to mode 1;
• C corresponds to mode 2.

Mode 0: touch button A, B and C, and the LED Matrix will light corresponding color, corresponding rhythm will sound.
Mode 1: According to the light color of LED Matrix, press the corresponding button to play a whole piece of music. When the LED Matrix lights red, you are supposed to press A; when it lights yellow, you are supposed to press B; when it lights green, you are supposed to press C. If you make a mistake, the mistake number will add 1, until it is larger than the set mistake number, then the game will end, and red, yellow and green will light up at the same time. At this time, you should press the three buttons simultaneously to unlock the game, and play the game again. At the end of the music, if the mistake number is less than the set one, it will play a whole piece of music along with light.
Mode 2: It can play rhythm automatically, and you can switch the music with A, B and C.
