Tutorial will allow you to understand how to control the underlying It involves a bit more coding than the usual Arduino code and this Timer interrupts operate in the background over you main code allowing accurate repeatable timed actions. TIP: Find out how to create repeatable, reliable time periods with interrupts. It is - if you like - a template for what you need toĭo to get an interrupt going in your code. Use any other obscure interrupt that is not explicitly supported by theĪrduino software. You can also use this information for figuring out how to Need to know how to setup timer interrupts for exact period timing.
