When the push button is released, a timer starts counting. Simultaneously, a hall sensor detects when a spinning object with a magnet passes by and prints the elapsed times. Each pass is recorded along with the elapsed time. If 10 seconds passes without detecting another pass, the code prints "DONE" to the serial monitor.

1. Arduino Question:
I need an arduino code that does the following:
When a push button switched is released, a timer is started. A hall sensor simulataneously notes
each time a spinning object with a magnet on it passes by and prints out these times. Each time it
does pass by, the time elapsed is recorded. If the object does not pass by for ten seconds,
"DONE" is printed to the window.
Thank You
Solution
#define HALL_SENSOR 2 //macro definition of magnetic and LED pins
#define LED 4
int pirPin = 2;
int counter = 0;
int laststate = HIGH;
void setup()
{
pinsInit();
}
void loop()
{
if(counter <= 10){ //running until for 10 seconds
if(isNearMagnet()){ //checkng near magnet or not
turnOnLED(); //sqithch on indicator
}
counter++;
}
else{
Serial.println("DONE"); //printing DONE to console

2. }
}
