hide ellipse int duration = 1000; change the duration you change time you can text the time
```auto
int startMillis;
int duration = 1000;
void draw() {
background(0);
if (mousePressed) {
startMillis = millis();
}
if (millis() < startMillis + duration) {
ellipse(mouseX, mouseY, 10, 10);
}
}
```

:
```auto

int timerDuration = 2000;
// The time at which we start the timer
int startTime = 0;
// Whether or not the timer was started
boolean timerStarted = false;
void setup() {

}
void draw() {
background(255);
if (timerStarted) {
// We subtract the current time and the time when we started the timer
int currentDuration = millis() - startTime;
fill(0);
textAlign(CENTER, CENTER);
text(currentDuration, width / 2, height / 2);
// If the event is over
if (currentDuration > timerDuration) {

}
}
}
// When the mouse is pressed, take the current time and store it
void mousePressed() {
startTime = millis();

I was wrong to post the code but could it be used for the timer?
```auto
long time = 25*60000;
void setup() {
size(300,300);
}
boolean running = false;
long start = millis();
float a = 0;
void draw() {
if ( running ) {
a = (millis() - start)* TWO_PI/time;
if ( a > TWO_PI ) running = false;
}
noStroke();
background( 0 );
if ( running ) {
fill(128,255,0);
} else {
fill(255,0,0);
}
arc( 150,150,200,200, -PI/2, -PI/2 + a);
fill(0);
arc( 150,150,150,150, -PI/2, -PI/2 + a+.1 );
fill(255);
long rem = time - ( millis() - start );
if ( running ) {
int m = floor(rem/60000.0);
int s = int((rem/60000.0 - m) * 60);
text(nf(m,2)+":"+nf(s,2),135,150);
} else {
int m = floor(time/60000.0);
int s = int((time/60000.0 - m) * 60);
text(nf(m,2)+":"+nf(s,2),135,150);
}
}
void mousePressed() {
if ( !running ) {
start = millis();
running = true;
}
}
```

It is your project and code so you have to decide.
I would replace the inner arc() with a circle() and fill() that.
