Autonoumous Lego Car

Hi there,
here I designed an autonoumous car for lego. It´s all in one brick and you can print it without support. Things requiered and to keep in mind for building:

• arduino nano
• motor driver board l298n
• battery holder
• two servos (prepare for simple motor run be removing the plastic stop bit by the gears and connect two wires directly to the motor
• switch with 9mm diameter
• ultrasonic module HC-SR04

HELP NEEDED:
I forgot the coding ;-)
If you accidently find it on the web, please post it here
wires go like this

A1-A6 -> from the left (e.g. the powerconnection 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 tyres I printed LEGO.lxf tyres changed by mecabricks.com to stl file and double sized them.

Enjoy.

If you like it, please tip for creating further funny toys.
