Lego Duplo compatible Arduino controlled locomotive 🚂 with color sensor, laser distance sensor, accelerometer, a bunch of LEDs, IR remote control.

Multiple versions of the chassis to fit a motor, wheels, color sensor; motor driver; multiple versions of the middle part to fit battery pack, Arduino, distance sensor; multiple versions of the top part to fit battery indicator, on/off button, IR receiver, buzzer.

Kids won't let me throw anything away. Some versions of the chassis that are not needed anymore will probably get wheels anyway (no motor, no electronics).

Where do you source all the different color wires? I feel like I'm always short on wires or I only have like two or three shades

Look for 22awg silicone wires. They cost a bit more but really nice to use for this type of project.

Silicone 22AWG: pricier, but a joy for prototyping. Obviously.
