ART 4 The following program is written for a setup where a button is connected to pin 6 to pin 11 of an Arduino. Please explain what this program does. (10 points) and an LED is connect int brightness ivi ; int ButtonPin 6; int LEDPin 11; boolean buttonv LOW; void setup) pinMode (ButtonPin, INPUT); pinMode(LEDPin, oUTPUT); void loop() buttonv = digita!Read (ButtonPin); if(buttonv HIGH) { brightness lvl++ brightness_1v1 = brightness_1v1 % 16; // modulo 16 analogwrite (LEDPin, brightness_lvl 16); delay (500)
