From Theory to Reality: Building Your First Controller
You now know:
- Feedback loops (sense → decide → act)
- Sensors and actuators (eyes and hands)
- PID control (P + I + D = magic)
- Stability (trade-offs between speed and smoothness)
Time to apply it. We'll walk through three real projects you could actually build: a temperature controller, a line-following robot, and an auto-balancing platform.
