Arduino pulseIn: Pulsein Measures high or low periods of a signal in microseconds. Why is your pulseIn measurement inaccurate - Find out here. Why does one function need interrupts On, while the other one needs them Off? There are two functions pulseIn and pulseInLong... Find out the ...

pulseIn() and pulseInLong() in Arduino - If there is an incoming pulse on a pin, and you need to measure the duration of the pulse then the pulseIn() function comes in handy.SyntaxThe syntax is −pulseIn(pin, value)Where pin is the number of the pin on
How to use pulseIn() Function with Arduino. Learn pulseIn() example code, reference, definition. Reads a pulse (either HIGH or LOW) on a pin. Return The length of the pulse (in microseconds) or 0 if no pulse started before the timeout. What is Arduino pu
