Most of today's crop is a wave of near-identical Emertxe internship presentations for the same EV/ADAS Dashboard project — decent student work, but hard to pick a standout when nine videos describe the same rubric-driven capstone. This ATtiny tutorial breaks the pattern by teaching something concrete you can actually try in a browser tonight.

The ATtiny family (ATtiny13, ATtiny85, etc.) is worth knowing because it sits at the opposite end of the microcontroller spectrum from an STM32 or even an ATmega328. You get 8 pins, a kilobyte or two of flash, and the discipline of writing code that fits in that footprint. It's the chip you reach for when you want an Arduino-class project shrunk down to a coin cell and a single SOIC-8 package — wearables, badges, tiny sensor nodes.

Doing this in Tinkercad is a smart pedagogical choice. New embedded developers often stall on toolchain setup: fuse bits, ISP programmers, avrdude incantations. Tinkercad sidesteps all of that so a beginner can focus on the actual mental model — pin direction registers, the blink loop, timing — and get a working simulation before they've spent a cent on hardware. Once the logic clicks in simulation, transferring to a real ATtiny with a USBasp is a much smaller step.
