Arduino LED Magic: Unveiling the Touch Sensor Control
Hello Arduino Enthusiasts!
I'm excited to share a captivating project that combines the charm of touch sensors with the enchanting glow of LEDs. In my recent YouTube tutorial, we embarked on an Arduino adventure, creating a sequence of LEDs that respond to the gentle touch of a sensor. If you missed the video or need the code for reference, you're in the right place!
The Project: Touch Sensor LED Control
Picture this: a touch sets off a mesmerizing dance of LEDs, each lighting up in sequence. Thanks to Arduino, this dreamy scenario becomes a reality. The touch sensor becomes our magical wand, and the LEDs respond by lighting up one after another, creating a captivating visual display.
The Code
Here's the Arduino code for the project:
```cpp
const int touchSensorPin = 2;
const int ledPins[] = {13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3};
const int numLEDs = sizeof(ledPins) / sizeof(ledPins[0]);
const int delayTime = 500;
void setup() {
pinMode(touchSensorPin, INPUT);
for (int i = 0; i < numLEDs; i++) {
pinMode(ledPins[i], OUTPUT);
digitalWrite(ledPins[i], LOW); // Set all LEDs initially off
}
}
void loop() {
static int currentLED = 0;
if (digitalRead(touchSensorPin) == HIGH) {
digitalWrite(ledPins[currentLED], HIGH);
delay(delayTime);
digitalWrite(ledPins[currentLED], LOW);
currentLED++;
if (currentLED == numLEDs) {
currentLED = 0; // Start over from the first LED
}
while (digitalRead(touchSensorPin) == HIGH) {
// Wait for touch sensor to be released
}
}
}
```
Feel free to explore, modify, and experiment with the code. Copy and paste this into your Arduino IDE, and watch the magic unfold on your own Arduino Uno!
