Microsecond Delays

Overview

In addition to the standard delay function which is measured in milliseconds, there is also a microsecond delay measured in, you guessed it, microseconds. Up until now, you have not needed shorter delays in your projects, but as you start creating frequencies to make sounds, shorter delays will be helpful.

delayMicroseconds(300);  // Note that for every millisecond there are 1000 microseconds.
