A week of Arduino Millis()

By far one of the most powerful functions of the Arduino library is the millis() counter. It is also one of the most misunderstood functions. Mastering millis() can unlock incredible amounts of potential with an Arduino. That’s why I’m spending an entire week on millis().

Each day this week I’m posting a new example of how to use millis() in your code. Each will be cataloged on this newly created Arduino Millis() Cookbook Page. If you have ideas for other examples, leave comments below.

Also, quick note. In doing this work I realized there was some issues with my previous Multitasking with Millis and How to Reset Millis() (hint, you don’t) posts which I’ve now corrected.

Enjoy this blast from the past, unless you are one of the 3 million subscribers mentioned in AOL’s 2012 Annual Report, which still use dial-up!
