k-shoot mania 旋鈕 可變電阻製作詳細說明

相關連接~
V-USB k-shoot mania controller for Arduino

這次我使用雙連後抽200K可變電阻(這個雙連後抽手感不太好阿QAQ)

因為上次改造時其中一片互換

另一方向外殼沒挖洞會造成接點夾到外殼
為了省麻煩就直接買雙連後抽

 雙連後抽200K可變電阻

接下來進行改造

把紅色圈固定用的東西拆開

從這個方向比較好施工

拆開後比較容易拿尖嘴鉗或剝線鉗進去施工

拿尖嘴鉗或剝線鉗把紅圈地方壓平
並轉轉看會不會被卡到
這樣就完成可變電阻無限旋轉了

再來照電路圖接線

硬體部分OK

Arduino 測試程式

const int analogInPin = A0;
const int analogInPin1 = A1;
void setup() {
  Serial.begin(9600); 
}
void loop() {
  Serial.print("val0 = " );                       
  Serial.print(analogRead(analogInPin));      
  Serial.print("\tval1 = " );                       
  Serial.println(analogRead(analogInPin1));      
  delay(200);                     
}

旋轉可變電阻(用雙連後抽小心別碰到後面的接點會影響數值)
確定旋轉同一方向
兩邊數值同時上升或同時下降

你會發現
當數值0在往下轉時換變成1019(沒到1023可能是1K歐姆電阻分壓到)
0到最大值中間有出現900以上的數值(不確定產生的原因...)

寫個左轉+1 右轉-1的測試程式
濾掉不可靠的區域 0以下 900以上
當其中一片在此區域時不理會他，採另外一片的數值當參考
沒問題的話就已經成功了~

const int analogInPin = A0;
const int analogInPin1 = A1;
int newValue[2]={0,0};
int oldValue[2]={0,0};
int count = 0;
void setup() {
    Serial.begin(9600);
  oldValue[0] = analogRead(analogInPin) ;
  oldValue[1] = analogRead(analogInPin1) ;
}

    newValue[0]=analogRead(analogInPin);
    newValue[1]=analogRead(analogInPin1);
    rotary(oldValue,newValue);

    delay(10);
