#Devlog 2 — 7 Hours Later… I Built My Own Arduino 😭

Today was the big build day for ArduCore.

I spent almost 7 hours designing and finishing my custom Arduino-style development board using the DIP ATmega328P.

This isn’t using a ready-made Arduino board — I built the main circuit myself and had to figure out how all the important parts connect and work together.

One thing I learned is that this board doesn’t have a built-in USB programmer, so I’ll need to use another Arduino as an ISP programmer/burner to upload the bootloader and program the ATmega328P.

Today I:

• Finished the schematic
• Designed the PCB
• Worked through the component connections
• Figured out the ATmega328P DIP setup
• Finished the board design
• Recorded the whole ~7 hour build session

And finally… ArduCore is complete! 🚀

Now comes the fun part — getting the actual hardware, programming it, and seeing if my board really works. 👀
