格羅夫 - 拇指操縱桿
Grove - 拇指操縱桿是 Grove 兼容模塊，與 PS2（PlayStation 2）控制器上的 “模擬” 操縱桿非常相似。兩個方向運動將輸出不同的模擬信號，因為它們實際上是兩個電位計。每個電阻約 10K。
操縱桿還有一個可用於特殊應用的按鈕。當模塊處於工作模式時，它輸出代表兩個方向的兩個模擬值。與按下按鈕時的 1023 左右的普通操縱桿相比，該值被限制在較小的範圍內（例如 200〜700），以便 MCU 可以檢測按下操作。

Grove - Thumb Joystick is a Grove compatible module which is very similar to the 'analog' joystick on PS2 (PlayStation 2) controllers. Two direction movements will output different analog signals as they are actually two potentiometers. The resistor is ~10k for each.
The joystick also has a push button that can be used for special applications. When the module is in working mode, it outputs two analog values representing two directions. The value is restricted in a smaller range (e.g 200~700)compared to the normal joystick that is around 1023 when the button is pushed, so that the MCU can detect the action of pressing.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

DIY a Raspberry Game - 2048
In this project, we rewrote the game 【2048】in Python on Raspberry Pi, and made a little change with it. The numbers in the grid are swapped with a series of words that explain the the process of 【how does an idea become a real product in the market】
