The Brains: Task Masters vs. Mini Computers
Circuits flow electricity, but "Brains" tell electricity when to flow. Discover the two main types of brains used in robotics, and learn when to use which.
1. Meet the Brains
When you want to build a robot, you need a "brain" to control the motors, read the sensors, and make decisions. In the maker world, there are two famous brains.
The Task Master
Microcontroller (e.g., Arduino)
⚡
Super Fast Reflexes
It only runs ONE program. As soon as you give it power, it instantly runs that code over and over again.

📱
No Screen or Apps
You can't plug a monitor into it. It doesn't have an operating system like Windows or Mac.

The Mini Brain
Mini-Computer (e.g., Raspberry Pi)
💻
A Full Computer
It runs an Operating System. You can plug in a mouse, keyboard, and monitor and browse the web!

Slower Reflexes
Because it's running a whole OS in the background, it might be a tiny bit delayed when trying to perfectly time a spinning motor.
