Taming Servo Startups: From Nervous Twitch to Intentional Control

Servo jitter at startup isn't a code problem—it's a hardware architecture issue that can disqualify competition robots and damage the credibility of interactive projects. Most Arduino tutorials overlook the critical role of power design and signal timing, yet the solution is elegantly simple: use dedicated power supplies, delay signal attachment, and implement smooth ramping instead of abrupt position changes. These three practices transform erratic startups into controlled, purposeful behavior.
