In this tutorial, we’ll discuss Arduino TimerOne Library<\/strong> how it works, and how to use it to handle periodic tasks (functions). The Arduino TimerOne library can be easily installed within Arduino IDE itself. It provides users with useful APIs to configure and use the 16-Bit Timer1 for generating & handling periodic interrupts and also to generate PWM signals with controllable frequency and duty cycle.<\/p>\n\n\n\n

We’ll create a couple of Arduino TimerOne Example Projects<\/strong> in this tutorial to practice what we’ll learn all the way through. Without further ado, let’s get right into it!<\/p>\n\n\n

    Timer modules in Arduino provide precise timing functionality. They allow us to perform various tasks, such as generating accurate delays, creating periodic events, measuring time intervals, and meeting the time requirements of the target application.<\/p>\n\n\n\n

    Each Arduino board has its target microcontroller that has its own set of hardware timers. Therefore, we always need to refer to the respective datasheet of the target microcontroller to know more about its hardware capabilities and how to make the best use of it.<\/p>\n\n\n
