Grove Thumb Joystick 搖桿模組
Grove Thumb Joystick 搖桿模組是Grove兼容模組，與PS2（PlayStation 2）控制器上的“模擬”操縱桿非常相似。兩個方向的移動將輸出不同的模擬信號，因為它們實際上是兩個電位器。電阻器每個〜10K。操縱桿還有一個可用於特殊應用的按鈕。當模組處於工作模式時，輸出代表兩個方向的兩個模擬值。該值在一個較小的範圍（例如200〜700）的限制相比於正常操縱桿即圍繞1023當按鈕被按下時，使得MCU可以檢測按壓的動作。

Grove Thumb Joystick
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.
