双轴按键摇杆主要由两个10K的电位器和一个按键开关组成，两个电位器随着摇杆扭转角度分别输出X、Y轴上对应的电压值，在Z轴方向上按下摇杆可触发轻触按键。在配套机械结构的作用下，无外力扭动的摇杆初始状态下，两个电位器都处在量程的中间位置。

2.2 电路原理图

这里单片机主控学长选择arduino，可选其他模块，如stm32

双轴按键摇杆模块的VCC、GND分别连接开发板的5V、GND，模块的X轴输出、Y轴输出分别连接开发板的模拟引脚A0、A1，模块的Z轴输出连接开发板数字引脚2。

3 实现效果

4 测试代码

/*

* JoyStick

* 双轴按键摇杆

*/

#define pinX A0

#define pinY A1

#define pinK 2

int value = 0

void setup()

{

pinMode(pinK, INPUT)

Serial.begin(9600)

}

void loop()

{

value = analogRead(pinX)

Serial.print("X: ")

Serial.print(value)

value = analogRead(pinY)

Serial.print(" Y: ")

Serial.print(value)

value = digitalRead(pinK)

Serial.print(" Z: ")

Serial.println(value)

delay(1000)

}

登录后复制

烧录代码后，打开串口监视器，波特率设置成与程序中相一致的9600，扭动摇杆，监视器将显示X、Y轴对应的电压对应的AD数值。
