I built a micro-quadcopter and a matching handheld controller that communicate using ESP-NOW for ultra-low-latency, router-free control. I designed and printed the airframe, motor mounts, and controller enclosure in Fusion 360, then wrote Arduino/C++ firmware for both sides. The controller samples dual joysticks and failsafe switches, applies calibration, and transmits 14-byte control packets at 100 Hz. Onboard the drone, an IMU feeds a PID-based stabilizer and a motor mixer that drives four ESCs. Highlights: sub-10 ms input-to-motor latency, configurable rates/expo, soft-arm and link-loss failsafe, and modular code structure for easy tuning. This project combines embedded systems, real-time comms, and CAD into a compact, testable platform.
