Try to make the picture occupy a larger area, and connect three WS2812 lanterns and one RGB lantern and an onboard pin 2 external interrupt touch panel and pin 2 Pin indicator light. Try to keep the style simple and cute, you can give it to friends and use it for decoration.
Test code:

```
#include
#define DATA_PIN 4 //Set the pin
#define LED_TYPE WS2812 //Lamp strip type
#define NUM_LEDS 3 //Number of lamp beads
#define COLOR_ORDER GRB //Lamp bead order
# define BRIGHTNESS 128
uint8_t max_brightness = 128; //Maximum brightness
int i = 0;
CRGB leds[NUM_LEDS]; //Name the light strip
void setup() {
// put your setup code here, to run once:
FastLED.addLeds< LED_TYPE, DATA_PIN, COLOR_ORDER>(leds, NUM_LEDS); //Initialize the light strip
FastLED.setBrightness(max_brightness); //Set the brightness of the light strip
pinMode(2, INPUT);
}

void loop() {
// put your main code here , to run repeatedly:
Serial.println(digitalRead(2));
if (digitalRead(2))
{
if(i>9)i=0;
i++;
leds[0] = CRGB(i, 0, 10 - i) ;
leds[1] = CRGB(10 - i, i, 0);
leds[2] = CRGB(0, 10 - i, i);
FastLED.show();
delay(10);
}
}
```
