非常感谢您的提问!以下是一个基于Arduino的LCD显示滚动条,并可以滑动滑块的例程:
```
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int sliderPos = 0;
int sliderMax = 10;
void setup() {
lcd.begin(16, 2);
lcd.clear();
lcd.print("Scrolling Bar");
}
void loop() {
lcd.setCursor(0, 1);
lcd.print("[");
for (int i = 0; i < sliderMax; i++) {
if (i == sliderPos) {
lcd.print("=");
} else {
lcd.print("-");
}
}
lcd.print("]");
// Read the analog input from a potentiometer to control the slider position
int potVal = analogRead(A0);
sliderPos = map(potVal, 0, 1023, 0, sliderMax - 1);
delay(100);
}
```
希望这个例程能够帮助到您!
