starting from my previous project I decided to make a new controller for 3-channel radio controls like my Spektrum dx3s. I added the reversing light, a pair of white headlights that light up at maximum speed and finally the flashing direction indicators.

through the radio channel aux 3ch I can control a micro camera in the cabin that can turn with the steering wheel or it can be set fixed that looks ahead. the circuit and the sketch work very well, I mounted them on all my trucks. all parameters can be set as desired.

EXPANDED TECHNICAL DETAILS

High-Fidelity FPV Mobility Hub

This project transforms a standard 3-channel RC radio system into a professional FPV (First Person View) dashboard with synchronized camera movement and lighting.

• 3-Channel PWM Decoding Logic: The Arduino intercepts the PWM signals from a standard RC receiver. Channel 3 is mapped to a dedicated sub-menu for toggling high-powered "Night-Driving" LEDs.
• Pan-Tilt Servo Gimbals synchronization: The FPV camera is mounted on a micro-servo gimbal. The Arduino mixes the "Steering" channel data with the gimbal logic, allowing the camera to "Look into the Turn" automatically as you steer the car.

Performance

• Sub-10ms Command Latency: Optimized for high-speed racing; the Arduino processes the receiver signals and updates the servos and lights with near-instant responsiveness, essential for FPV driving.
