Hello friends this time I came up with very useful PCB which is Home Automation PCB. Yes arduino is widely used in DIY home automation projects. Many of makers used bread board or zero PCB for their ...

After you’ve taken the plunge and decided to learn how to etch your own circuit boards, you’ll quickly find even the simplest boards are still out of your grasp. This is due mostly to the two-layer ...

The Arduino PCB Ink Plotter CNC Machine is a DIY project that features a arduino running GRBL CNC firmware. In this project, it uses a marker that is suitable for plotting or marking the PCB for board ...
