servo_circuit Most PID tutorials show you a temperature controller. Here's why that's misleading: thermal systems have massive lag and forgive sloppy tuning. Try the same gains on a quadcopter's roll axis and you get 50Hz oscillations that rip it apart. The time constant matters more than the algorithm. A 100ms thermal loop and a 2ms motor loop aren't even the same problem—one's about patience, the other's about phase margin before you excite mechanical resonances. Pick your teaching example by its dynamics, not its familiarity.
