RC Car v0 – v2
Personal project — learning by iterating · 2023
Before v3 came three earlier cars, each built to learn Arduino circuits, motors, IR remote control, motor drivers and the Arduino IDE — and each one taught me something from what broke or fell short.
v2 — Roll Cage
Added a roll cage and condensed the chassis to lower material cost. Result: the cage was too weak and the body too narrow to fit the circuits inside — fixed in v3.
v1 — Custom Chassis + OLED
Redesigned the chassis for a better circuit layout, and added an OLED that shows the last direction command from the IR remote. It worked (with a weak IR signal) until an accidental 3 ft drop damaged the circuits.
v0 — First Attempt & CAD Workshop
A tutorial-sourced 3D-printed chassis with self-designed motor mounts. Didn't work — circuit error and insufficient power — but it started everything. A CAD workshop along the way covered sketching and extruding, measuring real parts with calipers, and building a rotating DC-motor wheel assembly.
