9. Single Double Click and Long Press Detection

How do you plan to solve it?

To start the serial communication, set up an internal pull-up resistor on Arduino digital pin 7. To address switch noise, use robust debouncing with a 50 ms delay. Track press/release timing to identify single clicks click fast with the mouse and when double clicks click fast 2 times and lastly for long presses hold the click/button on the mouse and release.

/*Paste your code here*/
const int buttonPin = 7;
unsigned long press = 0;
unsigned long release = 0;
int Count = 0;
void setup() {
pinMode(buttonPin, INPUT_PULLUP);   
Serial.begin(9600);
}
void loop() {
int state = digitalRead(buttonPin);
if (state == LOW && press == 0) {
press = millis(); 
}
if (state == HIGH && press > 0) {
release = millis() - press; 
 press = 0;
if (release > 800) {        
Serial.println("Long press");
Count = 0;              
} else {
Count++;
delay(200);  
if (Count == 1) {
Serial.println("Single click");
} else if (Count == 2) {
Serial.println("Double click");
Count = 0;           
}
}
}
}
