关于可调试灯光程序的问题
const int analogPin = A0;const int ledCount = 10;
int ledPins[] = {
2, 3, 4, 5, 6, 7,8,9,10,11 };
void setup() {
Serial.begin(9600);
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
pinMode(ledPins, OUTPUT);
}
}
void loop() {
int sensorReading = analogRead(analogPin);
int ledLevel = map(sensorReading, 0, 1023, 0, ledCount);
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
if (thisLed < ledLevel) {
digitalWrite(ledPins, HIGH);
Serial.println(sensorReading);
}
else {
digitalWrite(ledPins, LOW);
}
}
}

以上语句及变量在该程序中的具体含义，求解
——————————————————————————————-
以上程序仅仅只是通过改变电流大小来控制各个小灯的简单程序，但本人有几处地方不是太明确，求助
const int analogPin = A0; // the pin that the potentiometer is attached to
const int ledCount = 10; // the number of LEDs in the bar graph
int ledPins[] = {
2, 3, 4, 5, 6, 7,8,9,10,11 }; // an array of pin numbers to which LEDs are attached
void setup() {
Serial.begin(9600);
// loop over the pin array and set them all to output:
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
pinMode(ledPins, OUTPUT);
}
}
void loop() {
// read the potentiometer:
int sensorReading = analogRead(analogPin);
// map the result to a range from 0 to the number of LEDs:
int ledLevel = map(sensorReading, 0, 1023, 0, ledCount);
// loop over the LED array:
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
// if the array element's index is less than ledLevel,
// turn the pin for this element on:
if (thisLed < ledLevel) {
digitalWrite(ledPins, HIGH);
Serial.println(sensorReading);
}
// turn off all pins higher than the ledLevel:
else {
digitalWrite(ledPins, LOW);
}
}
}
ledCount表示所用的led有幾顆，與後面的ledPins[]數量對應
map(sensorReading, 0, 1023, 0, ledCount)這句是等比例縮放sensorReading
analogRead()的範圍0~1023，要轉換成0~ledCount，也就是0~10 非常感谢，懂了，谢谢帮忙{:soso_e179:}{:soso_e100:}
