I need to reset knock sensor after a hit.Can you tell me if that’s possible with out physically hitting the sensor.Thanks

What knock sensor?

fast draw timer

sorry here is code

#include <SoftwareSerial.h>


unsigned long start, stop;

const int knockSensor = A1;
const int ledPin = 13;
const int softwareTx = 8;
const int softwareRx = 7;

SoftwareSerial s7s(softwareRx, softwareTx);

unsigned int counter = 0;  // This variable will count up to 65k
char tempString[10];  // Will be used with sprintf to create strings

void setup() {
randomSeed(analogRead(0));
pinMode(ledPin, OUTPUT);
s7s.begin(9600);
 
}
void loop() {

while (analogRead(knockSensor) <=10);// wait until sensor greater than 10
 
delay(1000);
for (int i=0; i<3; i++)// declares i, tests if less
{// than 10, increments i by 1 until i equals 3
digitalWrite(13, HIGH);// turns pin 13 on
delay(500);// pauses for 1/2 second
digitalWrite(13, LOW); // turns pin 13 off
delay(500);//pauses for 1/2 second
}
delay(random(2000, 5000)); // delay from 2 to 5 seconds
digitalWrite(ledPin, HIGH);// light turns on 
start = millis();
while (true) {

 s7s.print((long)(millis() - start) / 1000.0);
    if (analogRead(knockSensor) >= 10) { // if sensor greater than 10 counter stops
      stop = millis();
     break; // stop's while loop 
    }
}

digitalWrite(ledPin, LOW);
s7s.print((long)(stop - start) / 1000.0); // calculate's time time
delay(3000);
{
    s7s.write(0x76);  // Clear display command
  }


}

No, I deliberately asked about what knock sensor that you have. What is connected to analog input A1 on your arduino? How do we know how it functions if we do not know what it is?

Piezo Knock Sensor

At which point in the program does it get stuck where you want it to continue? And by what trigger? There are 2 places where it gets stuck until a knock is detected.

Please be creative and give precise suggestions what you want as a different solution. I don’t do “rewrite my code” requests. I want you to understand that code first.

I need to reset knock sensor after a hit.

Since you can’t be bothered to identify the sensor, check for a reset button.

Completely forgot about that. There’s a button on the Arduino board to do what you want.

Thanks, Valen! I forgot about that one too.
