Autonoumous Lego Car

thingiverse

Hi there! I designed an autonomous car for Lego that's all in one brick, perfect for printing without support. Here are the things required to keep in mind when building: * Arduino Nano * Motor driver board L298N * Battery holder * Two servos (to prepare for simple motor runs, remove the plastic stop bit by the gears and connect two wires directly to the motor) * Switch with 9mm diameter * Ultrasonic module HC-SR04 I need help with coding, though - I've forgotten it. If you happen to find it online, please post it here. As for wiring: * A1-A6 go from the left (the power connection side of the L298N) to the right * The two pins above the first and last pin at the L298N are for further power, if needed; add another battery * HC-SR04 goes to: + Trigger: D9 + Echo: D8 For tires, I used LEGO.lxf tires changed by mecabricks.com to an STL file and doubled their size. Enjoy! If you like it, please tip for creating more funny toys!
