Arduino timer how to#
Timer speed (Hz) = (Arduino clock speed (16 Mhz))/ prescalerĪfter this, let’s refer to the data sheet of ATmega328 as it’ll help us understand the rest of the process more coherently.In this tutorial we will learn how to make a Countdown Timer, where you can set time with one button and start the timer with another button. A prescaler dictates the speed of your timer according the the following equation: This number which we use to divide is known as the Prescaler, it helps us in bringing the high-frequency base clock down to match our application. In this blog, we’ll be exploring these timers and have a look at an example to get an idea about using them.Ī 16Mhz clock acts as a base clock in the Arduino Uno, but since 16Mhz is too fast for our application, we’ll have to divide it by some number in order to make it feasible for our use. Note: Difference between 8 and 16 bit is the timer resolution - 8 bit ranges for (0–255) values and 16 bit ranges for (0–65535) values. Timer2 - An 8 bit timer used by the Tone() library.Timer1 - A 16 bit timer used by the Servo() library.Timer0 - An 8 bit timer used by Arduino functions delay(), millis() and micros().

The ATmega328 built on the Arduino Uno has a total of 3 timers available, which are: Every timer has a counter which increments the timer on each tick of the timer’s clock.
