Turbocharge Your Arduino Performance with Smart Coding Techniques!

Arduino has made programming accessible to many. However, it often doesn’t get credit for its speed. That’s where [Playduino] steps in with a neat trick that could boost your favorite microcontroller by 50 times!

When you hear “50x speedup,” you might think of complex setups: overclocking, new crystals, and cooling systems. But no! This is achieved using stock hardware and just one simple hack: avoid using digitalWrite().

If you’re new to Arduino, digitalWrite() is a common function. It allows you to set a pin’s state—high or low. It’s user-friendly but quite slow. [Playduino] reveals what happens behind the scenes when you use this function and shows a faster method. This involves direct manipulation of hardware registers and some assembly language coding.

For those who learned embedded programming long ago, this might seem obvious. But if you started with Arduino, these techniques can be valuable additions to your skill set. Thanks to [Stephan Walters] for sharing this tip.

If you want even more speed, consider hardware methods like overclocking with liquid nitrogen, though that’s quite extreme!

Embracing these techniques can push your projects to new heights. Stay curious and keep exploring!
