What! Timer Interrupts? So easy and so useful.
PCBWay Big Sale Christmas 2020 https://pcbway.com $5 for 10 PCBs
I had to show you how to do this on an Arduino (Uno/Nano/Mini) as it's a very useful technique for offloading some processes, even though I tried to use the same technique on an ESP32 - and failed, as it was not the right way to do what I wanted. But here it is!
If you need a regularly triggered function (from every few microseconds to every few milliseconds) then this is a possible solution.
Not only that, I have an important (but sad) announcement about my future videos as well as a quick, 5-minute update on the Internet Web Radio (working so very well!)
