I'm going to try and fit this into our pool gate and use it as a (basic) lock for it!

Hi, I've got a problem. Whenever I power on the circuit, my solenoid constantly opens and closes, and the LED's don't light up. I used the exact same code from the video, as I used the GitHub file. Does anyone know how to fix this?

@janektamm4994 2 роки тому

is it possible to use a mobile phone nfc?

@PacoOtaktay 7 років тому

Good video. I like the example and how it works. I wonder if something like this could be used to put a RFID on a cat's caller(s) to grant them access to food. That way if you have a cat that is on a diet you can keep that one from eating more often then it should??

@XSpImmaLion 7 років тому

Not a very optimal solution... RFID works only on almost touching distance. Unless you can train the cat somehow... xD

@PacoOtaktay 7 років тому

XSportSeeker, I know it was a crazy idea. :) Just something I thought of there. lol

@XSpImmaLion 7 років тому

I like it! xD Perhaps some other wireless standard or one of the more limited/proprietary RFID spectrums could work... but not this particular Arduino shield.

@PacoOtaktay 7 років тому

XSportSeeker, That is true. Finding more and more interesting tech that can do some amazing stuff. Plus in the home maker world getting easier to slap things together and pull off some really creative things. :)

@DJglass2 6 років тому

Saw a commercial example of this in a pet store today. Has a hoop that cat/dog sticks its head through to read either tag on its collar or the registered chip then opens a cover over the food bowl. Once I saw the price I started searching for arduino ways of doing this.

@fitocs1940 Рік тому

whats is code we programaiton?

@ArrtusMusic 6 років тому

Quick question; is it possible to make the RFID reader scan continuously for the tag and then have it lock when the tag is absent? How would you go about doing that? Thank you

@IanBuckley42 6 років тому

Hi there, this is Ian who wrote the article. Without actually rewriting the code and testing it I'm not totally sure how this would work, but here is what I think might help. If you look in the loop function, there is a boolean called succesRead (look at line 210 of the code provided in the article), which switches when the reader gets a successful real from a key. Slightly further down in line 234 of the code, there is a while(!successRead); desinged to stop the code going further unless there is a reading. Try changing this while loop to something like while(!successRead) { digitalWrite(relay, HIGH); } which will hold the lock shut whenever the reader is not finding your key. Then, remove this line from the granted method (line 291) to stop the door auto locking after the setDelay. This is just my first thought on how to do this, and it may not work or be too elegant if it does. Let me know how you get on!

I want to make scooter immobiliser with that :) - read card, now you can turn on scoter (button works), and no 130db active buzzer sound. - read card again, now esc controller lost power and scooter is locked. Gyroscope is activated and position is stored - if any one moves the scooter alarm of 130db goes wild for 10sec, together with motion direction being disabled. Than alarm stops, motion detection re-enabled. Sound simple but there is no such system on the market at all right now - I was surprised by that🤷‍♂️ I think something as small as Pi Zero should be able to handle broth sensors and ... mosfet I guess. Any suggestions man, you def know more than I do, but I’m a quick learner :) would love to hear your thoughts / advice

No, RFID is a close range technology. I did a similar project with Bluetooth though, which works at a range of about 10m. Old project though, may be out of date now: www.makeuseof.com/tag/auto-locking-office-door-smartphone-proximity-sensor/

Also when I provide 12v supply all LED's automatically turn on and the solenoid lock also unlocks and doesnt lock again. Please help....

@stonynotdusty 6 років тому

Why use rfid when you could use a keypad system. Hunting around for keys seems to me no different to hunting around for cards except that batteries on diy systems are likely to run out. I prefer to have a displacement touchpad setup like this ukposts.info/have/v-deo/f4BepXyFhIuX24k.html with the advantage being that the digidoor example has backup power and excellent power management anyways. Good learning video though and perhaps a good system for hotels where you could have a logging system to tell when people checkout.

@zillionpanic8065 5 років тому

Is it possible to replace the leds to led strips, if so how

@MakeUseOf 5 років тому

Depends if you're talking single color 5050 strips, which require 12v to drive them and therefore some MOSFETs; or the much simpler WS2812b style "neopixels", which you could drive a few directly from the arduino 5v output, and can be inidividually controlled with a digital signal. More info: www.makeuseof.com/tag/connect-led-light-strips-arduino/

@MegaFahad1991 5 років тому

Can I use the same code but with arduino nano ???

@MakeUseOf 5 років тому

Should work, yes, but be careful with wiring, I believe the nano runs at 3.3v?

@nomansaeed4511 6 років тому

I make this but i have a problem I use 12v electric lock when lock open my arduino stuck then i restart it

@MakeUseOf 6 років тому

Are you using a relay? You shouldn't be interfacing a 12V lock directly with the Arduino, since the Arduino runs on 12V and the lock will draw far too much power. That will likely cause a reset (if not worse!)

@Kiiush 2 роки тому

Does it work with NFC tags?

@MakeUseOf 2 роки тому

We haven't tried, but it should do yes.

What us the range of rfid s?

@XSpImmaLion 7 років тому

For the most part, touching distance

@willybee3056 7 років тому

XSportSeeker oops,,, there is a yt vid that ALIVE AT 5 news cast showed them reading credit cards at over 15 feet... When I drove truck into a soy bean processing plant, they gave me a rfid card to track my truck and load through the plant. With the card laying on the dash , the readers were 30 to 40 feet away. My question was, is the Arduino boards that powerful? They don't use rfid chips in credit cards anymore... At least they say they don't. ... thanks for the reply....

@XSpImmaLion 7 років тому

No problems! You can definitely juice up readers or use different frequency spectrums to go through greater distances... but it requires far more power, and the Arduino module just won't do. xD For the most part, common readers you find to sell on the market basically requires touching distance to avoid crosstalking and interference, but the technology isn't limited to it... here, I found a good explainer: www.skyrfid.com/RFID_Tag_Read_Ranges.php There's one that can reach 500 meters! xD Probably proprietary and limited usage though...

@willybee3056 7 років тому

XSportSeeker Where I was going with that line ,, was ,, it would be neat to have a rfid card in your car that would unlock your door and turn on the porch lights when you drive in the driveway... With as easy as it is to change the cards with that system,,, you could rotate 4 or 5 cards for added security. Thanks for the reply...

A bit difficult to help given we can't see how you wired things. But for a start, check you haven'tgot anything from the +ve 12v rail going into the arduino - that would absolutely fry it.

Every time I scan the master card I get "Wipe Button Pressed - Master Card will be Erased! in 10 seconds". After it successfully wipes, the blues LED begins flashing again. I've triple checked all connections. Any insight?

@calderbmx1838 5 років тому

I had the same issue. Change the digital pin that the wipe button is supposed to be in the code. Because initially when you change the LED pin you set it to the same pin as the wipe button causing a never ending loop, when the blue led is on I believe.

@TelsctTelion 4 роки тому

Your wipe and the blue led are on the same digital pin
