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 arduino robot material required 2. Wiring and Schematic arduino-robot-wiring and schematic 3. Programming programming 4.Arduino robot arduino-robot It is a simple project which anyone can build, while we look forward to you sharing your projects with us in the comments below.
