Question
Transcribed Image Text:Explain the following code?
const int analogPin = A0;
const int ledCount = 10;
int ledPins[] = {
2, 3, 4, 5, 6, 7, 8, 9, 10, 11
};
void setup() {
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
pinMode(ledPins[thisLed], OUTPUT);
}
}
void loop() {
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);
for (int thisLed = 0; thisLed <ledCount; thisLed++) {
if (thisLed < ledLevel) {
digitalWrite(ledPins[thisLed], HIGH);
}
}
}
else {
digitalWrite(ledPins[thisLed], LOW);
}
