單純讓電阻值輸入
int potPin = 0; // 宣告類比腳位輸入的PIN腳
int val = 0; // 宣告變數Val = 0
void setup() {
Serial.begin(9600); //設定SerialPort的速度9600 = 9600bit/s
}
void loop() {
val = analogRead(potPin); // 用analogRead()這個函式讀取特定腳位的數值到變數val
Serial.print(val); //印出數值在Serial.Monitor
delay(150); //延遲讀入的時間為150ms
}
讓電阻值輸入，影響LED燈
int potPin = 0; // 宣告類比腳位輸入的PIN腳
int val = 0; // 宣告變數Val = 0
int ledPin = 9;
void setup() {
Serial.begin(9600); //設定SerialPort的速度9600 = 9600bit/s
}
void loop() {
val = analogRead(potPin); // 用analogRead()這個函式讀取特定腳位的數值到變數val
Serial.println(val); //印出數值在Serial.Monitor
delay(10); //延遲讀入的時間為10ms
analogWrite(ledPin, val/4);
