can someone please tell me how i can make a program, on the Arduino, that counts every time i read a specific analog value?

Question

arduino counter

Answer 1

int count = 0;
void loop() {
if(analogRead(A0)) {
count++;
}
}

Answer 2

if i understood your question properly, it should look like this:

const int yourValue=345;
int counter=0;

void setup(){
Serial.begin(115200);
}

void loop(){
if (analogRead(A0)==yourValue){
counter++;
Serial.println(counter);
}
}
