Robokart Barebones Arduino Circuit with Breadboard and IR sensor Electronic Components Electronic Hobby Kit

There are many reasons to want an Arduino circuit on a breadboard or PCB. Building the Arduino-compatible circuit on the breadboard or PCB takes up much less space than trying to stuff a standard Arduino board inside your project. Some projects don't always require every pin to be used on the I/O headers, or maybe you won't be using a shield, but you still want the brain of the Arduino at the heart of your project
