Grove – Thumb Joystick 拇指型搖桿

Grove – Thumb Joystick是Grove兼容模塊，非常類似於PS2（PlayStation 2）控制器上的“模擬”操縱桿。X軸和Y軸是兩個~10k電位器，通過生成模擬信號來控制2D運動。操縱桿還有一個按鈕，可用於特殊應用。當模塊處於工作模式時，它將輸出兩個模擬值，代表兩個方向。與普通操縱桿相比，其輸出值被限制在較小的範圍內（即200~800），只有在被按下時X值才會被設置為1023並且MCU可以檢測到按下的動作。

特徵

• Grove 相容介面，4PIN JST 2.0接口
• 5V / 3.3V 兼容
• 模擬輸出（當按下按鈕極大值將得到）
• Arduino 與樹莓派皆可使用

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.

Features

• Grove Compatible, with 4pin universe 2.0mm connector
• 5V/3.3V Compatible
• Analog Output(Maximal value will be got when the button is pushed)
