servo_circuit Most PID tutorials skip the part where your derivative term amplifies sensor noise into chaos. In practice, you're not just tuning gains—you're managing the tradeoff between responsiveness and the fact that real encoders jitter, IMUs drift, and sample rates lie. Low-pass filter your D term or watch your motor commands look like a seismograph during an earthquake. The math is clean; the signal never is.
