Automatic sliding gate making 

Thanks for notifying me, I've replaced Arduino code (.ino file) and added notepad (.txt file) as well, cheers and happy work!

Thanks bro

Controlling asynchronous motor can't be accomplished using H-bridge (as far as I know, maybe it could lower rotational speed by little if voltage is very low) because it's rotational speed is independent on the voltage. Frequency converter could be used but is expensive. Counting motor turns would be a little too complex for me, I didn't want to get involved in that, but certainly a great idea.

Hi Yaseen, glad you liked it. I've done this project two years ago and honestly have no idea on what inputs and outputs (COMM and OUT) are you talking about, can you clarify that part for me please?

@@Brezinjo you have taken signals from ir sensor to arduino nano can you kindly tell me which ports on ir sensor had you connected to arduino nano.

@@yaseensayyed8033 Yes, now I remember (forgot to mention that in the video). I can't remember which one I connected, but what I remember is you have to connect the IR sensor the way that it constantly gives the signal to Arduino when obstruction is not present and it stops sending the signal when obstruction occurs. That way you ensure that if the IR sensor stops working for some reason, motor won't start. So to simplify: 1. Connect the IR sensor (receiver) with 12-24 V and turn it on 2. Ensure that the obstruction is present, in other words don't turn on the transmitter. 2. Test/find which of the pins (COM or OUT) has 0 V. The other one should have 5 V 3. Connect Arduino pin D13 (or other digital input) to the 0 V pin. I hope this helps!

Thank you for asking this! @@Brezinjo

Capacitor start

Svakako pametan savjet, meni osobno to nebi odgovaralo iz razloga što mi pas često prilazi pored lese prilikom zatvaranja pa mi repom zna okinut signal IR senzora, onda bi opet trebao na daljinskom kliknut da se zatvaraju...Što se tiče rada u praksi, dobro radi ali ga zna zezat inducirano magnetsko polje tako da bi trebalo bolje zaštit/odvojit elektroniku od motora, strujne mreže i elektronike međusobno (Faradeyev kavez i slično, nažalost nemam osciloskop da mogu točno provjerit što najviše problema radi i otkud dolazi (vrlo vjv motor)) i svakako sam trebao stavit veći zupčanik da se brže otvara, veći zupčanik je dosta skup pa čekam bolja vremena da sve to do savršenstva izvedem...Srdačan pozdrav

@@Brezinjo. Hm. . ako će pas aktivirati senzor kod zatvaranja ne trebao imati problema. Vrata se tada otvaraju do krajnjeg prekidača, stoje predefinirano vrijeme (mislim da si stavio 5 sekundi) i same se zatvaraju. Razlog čudnog ponašanja Arduina može biti pad napona kod uključivanja elektromotora koji naglo povuče struju iz mreže. Stabilizator LM1117 na pločici često ne može to popraviti. Nekad može pomoći kondenzator većeg kapaciteta na pinu za napajanje Arduina. Odvajanje elektronike od energetskog dijela i mrežnih kablova svakako je poželjno kao i metalno uzemljeno kućište. Lp.

Adapters usually provide a bit of an overvoltage relative to their description, that's why I used 7.5V because it actually provided me with 12V. Always check the voltage of your adapter before using it on devices, otherwise you can damage them permanently :(

Button C pauses the gates by your own liking, but yes, when pressed again (button C) it continues to open all the way and closes. If you'd like to make them close when you want, it would be good to repurpose some of the unused buttons on the remote control and rewrite the code to your liking

@@Brezinjo Thank you very much

Hi, I'm glad you liked it, I've used carbon composition and carbon film resistors, values are highlighted in the wiring scheme provided in description and in the video (17:20). They vary from 1 K to 10 K (1000 - 10000 Ohms), best regards!

Thank you, 1 phase AC. I please you to watch the whole video before questioning or at least have a look at the schematic wiring of the project and mostly everything will be clear then

Most of the circuit and accessories is from ebay, if my memory serves me well, I think even all of it. Shopping links are in the description I will assist you in technicalities, no problem. I wish you happy work and As-salaamu Alaikum

I'm afraid I've never tried that so I don't know...

Thanks, brezinjo@hotmail.com

No need for a timed relay, I guess you meant just the regular relay that is cheaper than SSR. I think you could, but they operate on lower amperage which means they will wear out sooner, so it's just a precaution from my side of things.

Unfortunately no, I forgot to put that in the video :(

@@Brezinjo Hi thanks for that, can you maybe tell me where the blue line from D13 pin go to on the IR receiver? Many thanks Johannes

@@lappieslatandra Yes of course, it goes to relay that is inside the sensor. Relay has 2 outputs (power pins are ignored) as I recall, NC (normally closed) and NO (normally opened). You need to connect the wire to the NC (that way you ensure there is a constant signal when IR sensor is working and there is no obstruction between receiver and transmmiter)

@@Brezinjo Hi there, on the your schematic it look like the trigger pins are soldered together on the timer relay board. Can you please confirm that it is correct?

@@lappieslatandra I'm not sure on what trigger pins you mean, but I think they are not. For the timer relay board, black and red wires are power supply and two brown wires are going into the relay (that acts like a switch, hence the two wires). If I would solder them together, there would be no point in having the relay.

Of course there is ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-F-yk4Tyc44g.html

@@Brezinjo Thank you so much Sir i too am working on making my gate automatic Another query I had was why did u use that transistor with the IR sensor... what is its purpose and how does it work

@@shivamraikar4538Transistor is used as a switch for powering up appliances which utilize far more power than Arduino can handle on its own. It's a broad topic you should get pretty familiar with if you want to get this project done. I needed a transistor that could power the IR sensor who uses 18V, so in order to that I choose a transistor that has a peak voltage of 45 V just for safety precaution (voltage spikes are common in electronic circuits). You can use S8050 as well, but it will burn out at the first voltage spike, and naturally that is something you want to avoid. Some references for the transistor: en.wikipedia.org/wiki/Transistor ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jvlTKi9nMO0.html

@Trellistrey how can I help?

@@Brezinjo I put push buttons when I press button C it pauses but when I press again it doesn't resume , it just blinks the led ... Like it's floating

@@Trellistrey Yes, I had similar problem, don't know why that is. At first it worked perfectly, but after a while it didn't want to start after pausing. Maybe try rewriting the code for the button (try analogRead for the C button instead of digitalRead, maybe that would help). Cheers!

Well, the adapter itself is rated for 12 Volts, but it gives out around 18 volts(because it used to be for recharging, and those adapters almost always give more voltage then rated, they don't have steady supply voltage), but that's not a problem for IR sensor, because it can handle the input range from 12-24 volts.

If your question was can you put buttons instead of a receiver output signal wires. Answer is yes you can, but you have to power them from a 5 adapter naturally so they can send some signal to the Arduino when you press them, like you have to power the receiver itself.

@@Brezinjo thanks . Do you need to change the code to do so? Can you email me the code here? Kdevinda35@gmail.com

I received the code thank you

Yes it is, best regards!

@@Brezinjo thanks for the reply!! So do both main and auxiliary windings have the same resistance?

@@pakiki As far as I remember, I think they do, yes

Nažalost razumijem samo Hrvatski, Engleski, Bosanski, Srpski, donekle Slovenski i Slovački jezik

maybe you google searched BDK437, actually it is BD437 and it's quite common and easy to find on ebay and other websites, I wouldn't know right of the bat alternative one, but if you google transistor specifications, some results should pop-up for sure. Most important is that the alternative transistor has the current and Vceo equal or greater than BD437 and Vebo equal to 5V. Best regards

hi hello sir.. can i ask you something about the connection inside sensor there is a relay 1. com & 2. output ..the collector of BD437 is connect to com and the other one to D8 of arduino nano ?

@@jaojaopineda5361 regarding the wiring schematic picture, BD437 pin on the far left is called EMITTER and is connected to ground, pin on the far right is BASE and is connected to Arduino (as you mentioned), and finally pin in the middle is COLLECTOR and it is connected to a load, in this case the IR sensor (as you have said).

thanks for response..

hi sir... im almost done of my project but i have a question..if i open the door using the remote it is ok, then the limits switch is hit turn in high the closing door is close running is ok , but if there is a obstruction in the sensor didnt stop closing door what is the problem?

Yes, forgot to do that earlier, I've just put the code on google drive (link in the description).

@@Brezinjo thank you

Frende, ja te niš ne razmem :(

Želim ovaj grafikon printed circuit board @@Brezinjo

@@user-kc6ws8fe3h well I know there are some suppliers that can make you a custom made PCB, google a bit

Pozdrav, drago mi je da ti se sviđa, može na mail brezinjo@hotmail.com.

I gave shopping links in the description, Motor and housing is a bit trickier to obtain, maybe amazon or garage sales...

no problem, how can I be of service?

Can you give me your whatsapp number or can text on my number 00923425213266...... I wiill irritate you .i just want and share some ideas with you .

Receiver is not inside the housing. It was put on the top of the fence pillar, next to the signal lap, in a little green box, for better reception.

@@Brezinjo ohh i see, Im sorry sir, but by the way i try to make this on my father house. Thank you sir...
