The application prospect of pcb is very vast, you can applied it to the arduino/raspberry pi projects or assembled some chips into its surfaces etc.
Here we share a project where I saw in the instructable.com that diy an arduino robot. It is a simple robot which is operated by an arduino and what it does is that it just roams around and avoids obstacles.
1. Materials Required
2. Wiring and Schematic
It is a simple project which anyone can build, while we look forward to you sharing your projects with us in the comments below.
