⚠️Before you build — check compatibility
Line follower robot typically uses 2–4 low-RPM gear motors (50–150 RPM); 500 RPM is fast and may cause instability — 150 RPM is better balanced for control.
This kit does not include a chassis / base plate, wheels and a caster wheel / skid — a working line-follower robot also needs these.
To build this you'll also need jumper wires, a breadboard, and a USB cable to program the board — most Arduino/ESP32 sensor projects are prototyped on a breadboard before soldering.
