#202 Using Assembler 😵 within an Arduino Sketch - easy to do! 😊

Sometimes a time-critical or sensor-specific piece of code needs to be run in Assembler - either written by you or a 3rd party.
First PCB order free! https://www.pcbway.com 2-sided PCB just $5 for 10 pieces. Assembly for 10-pieces just $30.

It's so easy to do write a simple Assembler sketch even beginners will find it straightforward, and it's an interesting look at how things "bolt together" behind the scenes. Yes, really.

Don't worry, I'm not expecting anyone to start writing assembler programs but it's so easy you might be tempted just to try it out.
