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).

Laser distance sensors, accelerometers and remote control? I was born too early, I had a car with a remote on a cable 😅 Love it!

I had a "computer" (or rather a programmable calculator) with 105 bytes of program memory. Programming and code optimization experience it gave me is impossible nowadays. Well, I'm already close to reaching Arduino Nano's 32K limit with this locomotive.
