What an amazing instructor - love the approach, humor, and keeping it simple by using plain English... more, more!!

I like that you put a clutch in there, most other versions connect the motor directly to the switch.

I have always been a firm believer in that if you put technology into toys, then kids will WANT to learn - and what more universal toy than a train set - being a Lego train set, this now combines 3 hobbies into one - model trains, Lego and Arduino! Well done!

I didn't even know LEGO had a clutch! All the LEGO trains stuff is fairly unknown to me, I didn't know it was quite this sophisticated, but that might also be the impression your setup gives. Also; your videos are well presented and entertaining. Watching the one presented on hack-a-day made me want to watch more.

I understand that there's effectively nothing too complicated in this, but I'd just like you to know that you just blew my mind. I've never coded and you just hit hero status in my book. That would be a "Like" and a Subscribe!

Expect lots of ppl know this but there was a magnetically switched set for the older (12-15VDC) sets

Please come back man, I love your tutorials

they did make a track switch for the gray 12v trains but the are very rare so its just easier to make this

The older 12V system had switches that were remote controlled. 753 and 754 seems to be an older version (blue) while I had two in grey.

I built a couple of these, they're great! :) Can be modified easily to work with power functions motors as well.

Great video! I have a comment about your programming, and you have probably figured this out, but I feel I should put in my two cents worth. It's not a void. It's a subroutine. Void is the return type, which is to say, some subroutines return some value to the calling code, kind of like a function, and some don't. When a subroutine is meant to return a value you have to specify what type of value, like integer or float so the compiler knows how much memory to reserve for the return value. When a subroutine is meant to just perform some action and not return any value the return type is void (none, null or N/A) so the compiler knows it doesn't have to reserve any memory for the return value.

Amazing. Like that you can build a city and make it intelliegent.

Thank you so much for this video. It helped me a lot. But I use old 4,5v motors and a 12v train transformer to remote control it. It works perfect. Just like the old 12v stuff but with 9v tracks

Ich ärgere mich auch noch immer das LEGO hier keine elektrischen Weichen anbietet. So eine große Firma, und sie geben uns Kunden nicht das was wir möchten.. schade. Mal sehen wann endlich was rauskommt. Danke für dies Video !!

Lego DID solve this problem. The old 12v train system had motorised switches available.

Very clever.A very nice video to see.

Amazing! Thank you for explaining this so simply. Would you be able to post a list of parts used? I can't quite tell from the video which size gears and axles you used. Thanks!

Im not into the new gear, but as a child I am sure we had electronic points in the 12v days.

This series is really great! However, right now you are demonstrating how to modify the old 9V lego train kits, which are no longer produced. It'd be great if you could show us how to modify the newer RC ones.

Hello, your videos are very helpfull and i would like to control my lego 9v trains too. I have already an arduino and driver motor, coud you explain me in more details how the Motorized Track Switches works, and where i can find the 9V Motor with Gear Reduction 5225 ( i suppose)? thanks!

Any suggestions for when the switch is too stiff and the clutch engages too soon?

Good work mate I love it.

awesome love it

that moment when he says fuck when the train fell off XD

this is my favourite video

i really want to do this but i don't know how to code with arduino. do you suggest any getting started tutorials for working with lego

if you don't wana listen to the code stuff then skip to 6:02 and youl skip how the stuff works

Lego train swiches looked better 45 years ago.

you dont need to use arduino, you can also use lego mindstorms to control the train etc

This settles it, I'm getting an arduino. And Legos. For science.

One question: the original Lego 9V switch has a very strong spring (locking mechanism), and thus it takes lots of force to actuate it. Did you have to remove the spring on the downside (interior) of the switch, prior to building the motor onto it? Or is the Technic 9V motor, in combination with the clutch, strong enough?

Great videos

At 6:40 u can hear him swear

Very good

Great Nice Good Job

great serious. thanks. one question - how you build motor itself?

Can you provide the part numbers for the components used to build this for beginners?

Nice project

nice

very nice

I typed out my code but is failing to compile... what does '!' mean in LDR2state? and what does LightSensorCounter % 2 == 0 mean? thanks PJ

Lego made kits to solve that problem..... kit 7858

Amazing!, thank you, your elaboration are so useful, do you suggest another motor instead of Electric, Motor 9V Mini-Motor, newer/older versions (43362c01/71427c01), as its price is high and few lots on Bricklink?

very clever.

Nice

ty for this video!!!!

DO you mind stating the parts needed in words?:)

I liked

super puper automat !

Also I'm puzzled by you referring to the methods via their return types eg 'void Loop' etc. Is this a thing Arduino ppl do routinely? I thought you couldn't overload method names in Arduino, so the namespace would prevent a (say) 'void Loop' and an 'int Loop' both compiling? Sorry if I've missed something mind you, not an Arduino dev. Great vid tho.

when are you going to upload a new video?

Thank you!

I heard you say a bad word whenever the train stopped

how can we get station detector ????

@Arduino Lego Trains can you supply the code?

How to use to point switch sir i want to know this

Good

Anyone used a different motor for this? Or perhaps an stl file to print out this lego motor case and add hobby motor in instead?

6:41 listen

why not a remote control with a lego servo motor?

Wao »beautiful

how

Can you please give the code?

areal car kitena ke milta hai

Old news. The automatic infrared train detector is much better...... Trust me.

Is this dude darth vader

it would be better to work with a PF servo motor

this is soo hard

Why on earth are you calling functions "voids"?! Void is the return type of those particular functions, that is, they do not return anything, they are not "voids", they are functions without return values.
