Yf-s201 Proteus Library |verified|

pulseCount = 0; lastTime = now; attachInterrupt(digitalPinToInterrupt(2), pulseCounter, FALLING);

Verify that your pulse signal line is connected to Arduino Pin 2 ( INT0 ). If it is connected to an incorrect pin, the interrupt routine will never fire. Also, check that the test potentiometer wiper is feeding the correct analog control pin on the sensor model. yf-s201 proteus library
