Here’s a no-PCB Arduino that doesn’t obscure the DIP footprint of the AVR chip. It’s built on an ATmega88 chip, and includes a programming header, reset button, a couple of filtering caps ...

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear.

Apart from understanding the Arduino's code language, one of the most confusing parts about the platform — especially for beginners — is picking the right board to use in a project.

It can function as a remote control, a Bluetooth gamepad, or even a smart automation device—all tailored to individual needs.
