Mark's on a mission to whip up a pocket-friendly blinky LED board with its own microcontroller. To do the job, he’s thinking about the Microchip ATtiny416, an affordable microcontroller with multiple PWM outputs for some seriously cool lighting effects. Mark jumps right into it, tackling the challenge of finding budget-friendly components, especially all the required LEDs.
Next, Mark introduces a programming jig that makes it easy to test and program multiple boards. He also uses PlatformIO for Visual Studio Code, an extension that simplifies programming for both seasoned pros and those just dipping their toes into the maker waters.
Now, for the fun part! Mark takes you step-by-step through the stitching process, which uses stainless steel conductive thread. He shares practical tips on thread spacing, dodging short circuits, and testing the LEDs. Even with the huge amount of time he invests in the intricate stitching, Mark stays positive, successfully creating a mesmerizing chasing LED display.
As the video wraps up, Mark talks about how much his daughter loves the finished creation. He discusses future upgrades for a second version, teasing even more interactive features for those LED boards. This video isn't just a tutorial – it's an in-depth look into the world of festive wearables, inviting all the makers out there to jump in and create their own dazzling blinky LED boards!
