4WD RC car steering wheel not encolude component

This listing covers the steering-wheel/servo-steering element of a 4WD RC car build based on an Arduino Uno and an L293D motor driver IC — note that this specific product excludes the other build components (they must be sourced separately). In the full build, an L293D dual H-bridge handles drive-motor switching, while a separate SD3218 servo controls the steering axis.

Because servos and drive electronics run at different voltage needs, the build uses an LM2596 buck voltage regulator to step the 3×18650 battery pack’s voltage down to a stable 6V rail dedicated to powering the steering servo — protecting it from the higher raw pack voltage.

The rest of the referenced build uses four TT gearmotors (rated 3–12V) for drive, four wheels, an HC-05 Bluetooth module for wireless control, and an Arduino Uno as the controller — all of which pair with this steering component to form a complete Bluetooth-controlled 4WD RC car.

Features:
1. Steering component for a 4WD RC car build
2. Designed to pair with SD3218 servo for steering control
3. Part of a build using Arduino Uno + L293D motor driver
4. LM2596 regulator steps 18650 pack voltage down to 6V for the servo
5. Compatible with HC-05 Bluetooth control setups
6. Does not include full component set — steering element only
