I Built a Lego Turret on a Raspberry Pi 5 Robot PiCar-x — No Tutorial Existed

I bought the SunFounder PiCar-X robot car and wanted to add something no one had built before — a physical joystick controller, a 9G servo turret, and full Lego armor. When I searched for tutorials, nothing existed. So I figured it out myself and documented everything. In this video I show you: ✅ How to connect a joystick to the Robot HAT ADC pins ✅ How to wire a 9G servo turret on PWM pin P3 ✅ How to build Lego armor around the chassis ✅ How to combine the SunFounder app with custom Python code ✅ Every mistake I made and how I fixed it 🔗 Full source code and wiring diagrams: github.com/Unknownboykim/picarx-lego-turret 🛠️ HARDWARE USED: SunFounder PiCar-X Raspberry Pi Robot HAT V4 Joystick module 9G servo SG90 Lego bricks Jumper wires 🐍 SOFTWARE: Python 3 robot_hat library picarx library vilib library SunFounder Controller app 📺 Subscribe for more Raspberry Pi and robotics builds! #RaspberryPi #PiCarX #Robotics #Lego #Python #picar-x #SunFounder #RobotCar #DIY #Electronics #Coding
