ARDUINO AUTOMATED LEGO RAILCAR

[mtrkustoms]

Hi to all,

From the MTRkustoms factory we have the pleasure to present the ARDUINO AUTOMATED LEGO RAILCAR

Here you can see the Railcar in detail

This use modification pass the following phases

PF --> 9v --> Arduino Control

The original idea was very simple, have an autonomous and continuous Railcar in open circuits.

I based the function in a great cheap invent, The Arduino Board, this small, easy programming and low cost, gives me the chance to make it real with a cost below 10€, including a PWM motor controller L298N

Only 1 9v cable was "damaged" to convert its connection.

The cycle work is very simple, Railcar goes from end to end regulated by the L298N with a PWM velocity. When the Railcar hit the final of the track (switch detection) stops 5sec and go to the other end and stops 10sec (and able to the passengers to go down)

Time, velocity and stops time can be easy fixed by the programming.

Some pictures of the system

Cable connection boxes

To hide the Arduino board and the L298N I made a modern prefabricated transformation Station

Enjoy it

Great to see someone else putting an Arduino to use - especially a little Nano!

For future attempts, you might want to try an ultrasonic sensor at the end of your tracks instead of switches - that means you're not dependent on a physical contact to shut off the train (which can be unreliable sometimes). Here's a video to show you what I mean:

Nice work.

That's a great setup on many different dimensions- a tram running in the street, the automation, and perhaps the thing that stands out the most to me is the attention paid to the "transformer" building- a great job camouflaging the electronics.
