If you don’t understand a ton of circuit theory, have experience reading schematics, or played with a lot of circuits, then building your own schematic can seem daunting.
Though exciting, finding the right way to tackle this project has been tough! But I’m taking it in chunks.
5 months ago, I’d never designed a project from scratch. 5 months later, I’ve learned to design a PCB from a schematic, manufacture it, use a barebones microcontroller, 3D model with fusion360, write code that interacts with hardware, and much more. This was a crazy fun project!
So far, I have completed all of the goals I wanted to get done before college. This is huge! And now I’m bored…
A little under a month ago, my PCBs arrived! It has been a hilariously long wait to get everything else up to par.
Last we saw, I got the binary watch code working with the 32.768kHz clock and fuse bytes (aside from the buttons!
For the past week I’ve been debugging hardware and software to get my barebones ATmega328P to work with a 32.768kHz oscillator as Timer 2, which will tick outside of the sleeping microcontroller. This way I can keep track of time even as the microcontroller is off and saving power.
Last we talked about the Binary watch I was busy finishing up the second rendition of the working code and getting ready to complete the schematic.
