Have you ever felt like you use only a fraction of your Arduino’s capabilities? I feel that way all the time. So why not just start working with a bare ATtiny85 in the first place? For me, the answer has always been that doing so was just…terribly inconvenient. But it doesn’t have to be!
ATtiny Flasher is a tool that I built so that I could develop ATtiny-based projects in much the same way that I would if I were using a "grown-up" Arduino. That means having access to my favorite IDE, familiar libraries, and of course serial debugging capability. So please come have a look, and give me a chance to convince you that it’s just as satisfying (and just as much fun!) to work with ¢50 ATtiny13 as it is to rely on the fancy, multi-core MCUs to which you might be accustomed.
