Automatic trash can pull out cabinet with Arduino (DIY)
Вставка

- You want to build your own automatic drawer opener or automatic trash can pull out?
We are using and Arduino and two distance sensors to create an automatic and hands free way to open any cabinet or drawer.
This is an easy trash can / trash bin opener build.

Imagine open that thing at 3 o'clock when you are trying to steal something from the fridge 🤣🤣🤣
oh my god that so awesome thanks for the solution
Thank you!
Nice job on the opener. Not to take diminish your effort, but Blum makes slides and and opener that does this if anybody is interested. Is sells for about $250 US.
2021 nice idea, I would go with a bigger servo because when there is a full bin load that little guy will struggle :)
I like your content mate, very similar to mine, new subscriber from Aus! 🇦🇺🇦🇺
Am a little confused on the wiring. By any chance do you have a complete wiring diagram available? Ant help would be greatly appreciated. Thanks!
Hi, thanks for the videos guys, nice project ;-) Actually doing the same, is it possible to get the model/plan of the small box you've made to fix the servo ? I'll try to do it manually :)
Kindly share specs of the last item that made the drawer fully opened and its assembly
Thanks for the video. I was thinking about doing this in my kitchen and guessed that I was not the first to come up with the idea. I like your using 2 sensors to lessen the chance of a false open signal. I had not thought about that. I was thinking about using a linear actuator but after looking at your servo motor, I think it should work just as will, is more compact and cost much less.
Questions:
1) Does the load in the can(s) effect the operation? If the cans are full does the 25kg servo still do the job?
2) How do you think the servo will do with contamination? Do you think it'll be a problem if marinara sauce or wine gets spilled on the motor?
Hi!
Excellent questions!
1. We chose to use a servo because of the speed and we wanted it to pop open. In our cases it makes very little difference is the cans are full. BUT, that's mainly because construction of the "can system". It still slides easily when tings are heavy.
2. The servo we are using is water proof. So liquids will not contaminate any of the gears inside of the servo. So worst case you just wipe it off.
It is worth mentioning that it was almost a 50/50 chance that we were going to using a linear actuator. The main arguments for using a servo was the speed as well as it is easier to mount (for all viewers), especially when considering there might be a limited space behind the drawers.
Nice Job. They got it to work but installed drawer handles anyway ?
pal i could use um engine by passo replacing o servant engine?
I see you guys powered it with a usb power bank in the demo. Did you eventually plug it in to an outlet in the final installation? I'm wondering how long a large usb power bank will hold up as I don't have an outlet near my drawer.
Hi Fred! We connected it to an outlet.
If you are going to run it on batteries I would recommend using two PIR sensors instead, because of the lower consumption. And putting the chip to sleet. That way you can have the PIR sensors interrupt the sleep of the micro controller.
The drawback of using PIR sensors is that is might not detect if the user is wearing thick socks.
How would you do this with a button instead of the leg sweep? And if the drawer doesn't open fully, then what is a more powerful servo you recommend and how would you do that. Also will the same code work with a button. This video still helps so much btw.
Hi Sliccz! Of course you can use a button, the programming would be easier whiteout any concerns about timing on the IR sensors and so on. In the video we focused on a hands free solution (as mentioned in the video) vibration, push button and even voice command. Any bigger and smaller servos will work in this build. Before you buy a big ass servo, check the drawer if you can reduce friction or as in the video remove a damper or a spring. Good luck 👍🏻
@@DIYTECHBROS Thank you so much, also is there any extension arm that you would recommend for the servo and what is VCC. I don't have any type of spring of dampener on my drawer btw
Yes, you can use a button! If you need more power, you can just use a linear actuator!
Hello,
I tried making the project with arduino uno and mg995 servo motor but I am having an issue. The servo works sometimes and other times it gets stuck or doesn’t work at all. I would appreciate your help.
Liked your solution so much I applied your solution to my trashcan too. Works nicely, untill sun starts shining abundantly. Then its UV light starts to trigger UV sensors. Making this useless for my kitchen. Will revert to foot triggered push button.
Thanks! What I like about engineering is when less is more, so a solution for you would be to cover much of the receiving led with a black straw so it can only see where the reflection of the led would be :-)
Blum are the solution without overengineering
Blum is if you want to spend money. I think they have a good low cost solution.
Cool! Did not know about Blum. But, what a price tag... This solution you can integrate bluetooth or replace the Arduino with an ESP and connect it to Alexa :-)
Thanks!
Nice! How did you make the extra lenght arm?
Would love to know how you got the extra arm length as well. I just got the basics of this working and even initiated by Google Assistant, but now need to find out how to extend the arm length.
Hi. How do you avoid sunlight interference with the IR sensors ?
Probably because they are near the floor and concealed, they do not get much sunlight.
Hi, it is very interesting ! I want to apply to open the drawer of projector: 1) Is it possible to control open AND close by IR remote control? 2) can it open to a same distance every time? 3) And what is the device you use to make the pushing stronger ? Many thanks !
A smart vac could possibly trigger the servo and cause an accident.
We don't have a problem with that, BUT, it could potentially happen. Then you should calibrate the speed :)
Hi Guys, really need some help with a project. How can I open that drawer using a button?
Replace the sensor with a button - it's that easy!
@@DIYTECHBROS I'll need all the other parts? Thanks for replying too :)
Yes! The rest remains the same :-)
@@DIYTECHBROS Thanks A Ton!!
Hi Again Guys, Could you elaborate more on the VCCs and the grounding along with the changes for the button, maybe a more detailed video or any way I can coordinate with you? Would help me a lot!
I am trying to build the same exact unit. I have the sketch uploaded onto the arduino nano, and have the power supply hooked up. The motion sensor seems to work but the servo isnt moving. Do you have a way to test the servo or a check list?
oh and im not running a buzzer. should that change the sketch? (ive never worked w arduino boards before)
@@Lamsterdamz Hi! No, that does not matter. What's the make and model of the servo?
I believe it’s the same model as the one you have in the video
@@Lamsterdamz Then it seems like there is a whirring problem. Check all wires. Do you feel any resistance in the servo if you try to twist it (while running the script)? Also, where are you getting your power to the servo from?
From a 5v power supply
棒
Thanks!
Terrible design for a kitchen. Whoever designed this should be fired. Good solution but never should have been needed
