Cool. Useful. Love the outdoor shots. You stay safe too.
Lyndon Baptiste thanks bro, glad you like it, I realize I could add a lot more b role shots to easy to viewer
Hummingbirds :O , I would like to see more of that
yes will do
Love the choice for your workbench mat
Thanks, I picked it out myself
man I almost did the same thing!! hahaha found so ironic that youtube recommended me this when I was thinking about it these days, love it, keep up the good work
man, google probably listening, hid your thoughts. JK JK. thanks for the feedback. And you should make one. What's stopping you!
@@JustBarran I will pass on this one this time, but I sure will be working on some stuff so I can show to my 3 viewers!! subscribing
Did you consider using an IR Led & Sensor module to detect a hand wave? in stead of the Ultrasonic? EG something like
TCRT5000 ($0.23 from China) & Did you consider using a simple analogue servo driver instead of Arduino?
really good suggestions. I would have rathered used the amzn.to/3aaLb6z something like this but I used only what I had in this video. also looking to add more features. So really appreciated the suggestions. I think I might be able to make one of those TCRT5000 sensors, I have some IR transmitters and receivers actually come to think about it. hmmm ideassss
Good Video Dude! Very useful to have outside my house with hand sanitizer.
Thinkmoat thanks, took to do a upgraded version soon
Nice man! thank you.
Thanks for the comment. Going to drop version 2 of this soon
Sweet. Flat black all the way.
So Carlos TV yea the flat black was a good choice
So Carlos TV flat black 🙌🏽🙌🏽🙌🏽
This is great! would be a super fun project for anyone learning to build.
I think so too it was supper fun. and every problem is an opportunity for a solution. Thank for the comment and I hope you are also being safe during this pandemic.
@@JustBarran Pretty great opportunity to make a solution to help during this time and keep it fun and creative. Thank you, we are well, hope you and yours are as well.
Simple and easy to follow. Thanks a ton. By the way, how could I add some led lights maybe around 2 or 3 blue led's, just for the added decoration during triggers. Nothing was changed, just the added led. Is it possible? Thanks again
Hey man, I don’t see why not. On the uno we have tons of extra GPIOs( general purpose input and output) to use. I plan to make another video this weekend with a timer so stay tuned for that.
th-cam.com/video/WBzBj73NXb8/w-d-xo.html check out my new video with changes
Your videos are unique and distinct. I like that you commentate over your work. I am sick of all the other youtubers playing generic non copyrighted music. This will be my first Arduino project, thanks for the help. Can I use a 9V battery as a power source?
Zeyad Sadek hey, this comment means so much and I really appreciate it. That’s the same problem I have with other TH-cam videos. Not explaining the struggles 😂. I used a 9v battery originally and it worked with the soap dispenser but I was using the voltage regulator on the uno to power the servo with 5v which was enough for the soap dispenser but not for the hand sanitizer. It required alittle but more force. The servo is rated at 9g and 6v so what I had to do was power the servo straight from the battery (I using a 2s lipo here) and it worked great. Once you give it enough juice the servo does the job. You can get packs of these online.
This is also why i love this channel
hmmm i need one this bro....i supposed to do andrino in electrical eng.good stuff bro..much respect from tnt..btw i know u from IG
Hey man yea thanks for the comment and support on both IG and youtube. Look out for more videos coming soon, hopefully this Covid thing doesn’t reach me 😭. Stay safe
@@JustBarran aye yea true boi..i will be on the look out
excellent video, suggestions , expand it use a solenoid valve to open and close the water at the same time and use the battery indicator to display a count down while you wash your hands, cool video
haha YESSS. i Have a plan to do a count down timer. The solenoid valve kinda tricky at the moment since I don't have one and ordering parts has become very difficult.

Nice 👍 I ❤️ it.
Carlos Octavio Carillo thanks a lot of upgrade I could add also
Wow. I don't know anything about building anything but this is so cool 😄
Now u know know how to build something 🙌🏽👌🏾
Cool video! I rather the semi-gloss...Side note:That's not the proper way to wash your hands especially given this global pandemic..I will send you a video..stay safe and stay clean🤗
ANTONELLA NARINESINGH 😮 thanks I would definitely check up how to wash my hands better, can’t be too careful now.
Cool bruh... I want to try it... But how if i use motor servo without using battery (external power) and i just use USB power? Would it be strong enough to pull the wire on hand sanitizer ?
So this was a problem I had with this design. The 5v usb was not proving enough current for the motor to pull down the hand sanitizer. To get the full toque from the 9g servo you need to provide it with 6v. You can try a bigger servo at 5v and it may work but it depends on torque.
This video really helps, thanks! I made this with an attachment of hose, but whenever I try to put the battery, it automatically starts pumping; however after that it functions normally. Can you tell me what the problem is?
Hey, might have to check the ultrasound sensor, it might be trowing a error at the start cause in the problem, you can add a small delay in the setup of the code to help this.
@@JustBarran Thank you so much! You're really a big help, not only to me but to my fellow classmates as well. I should inform you that we did not use a relay module as we aim to produce a low-cost product. Is it still possible for it to function well? This is our link to our code, we would be greatly honored if you could give us your spare time and check our code, and tell us if it might be the source of our problem. Thank you so much! drive.google.com/drive/u/0/folders/1sz_ua12Pgs9vMnFUJ3sn0NQo6zbGLdawdrive.google.com/drive/u/0/folders/1sz_ua12Pgs9vMnFUJ3sn0NQo6zbGLdaw
Hi I'll try and check this out today
Dude, my servo couldnt pull the wire, why was that? Is it the bottle problem? Or is there any coding that make the servo stronger?
If you are using a micro servo, it has a Torque that varies depending on the voltage between 4 and 6 volts where you can really get the full 9g @ 6volts. It can also pull more than 200mha. If you are using 5volts off the Arduino regulator it might not be giving you enough power. I had that problem first. My suggestion is try powering the servo from a separate power/regulator. Make sure and tie the grounds. You can check out my newest video for an updated circuit diagram. th-cam.com/video/WBzBj73NXb8/w-d-xo.html. If that doesn’t work then your dispenser (bottle) might be too much for the servo to handle and you may need a bigger servo or a gear system to give you more torque. Hope this helps.
@@JustBarran well thanks mate, it workss
@@mr.jangwe3234 awesome happy to hear you got it.
What kind of servo did you use? I have one but kinda small, would it work?
Am using a 9gram servo. It was weak at first when I was running it off the Arduino 5v Regulator but when I had it running straight from the battery (7-6v) it had more than enough Torque. I put links to the servo I used in the description but I had these lying around and they are standard micro servos.
@@JustBarran thanks mate great help
Yooo great video, you might want to look into the information, "i" thing that does be in the top right corner to link other videos. :D or link them in the description as well, the ones you mention ofc :D
Usman Mohammed or yea, thanks for the suggestions
Hii thank you for the video ! Serial monitor seems to lag when my hand moves to distance less than 10 from the sensor. Also, my servo motor is not moving when connected to the circuit. However, when I test it, it is functioning. Do you know how to solve these ?
You could have a bad sensor, the serial monitor lags because the pulse in time use calculate the distance is timing out. This usually happens if the distance is less than 4cm or greater than 3meters. So I suspect is that. What you can do is www.arduino.cc/reference/en/language/functions/advanced-io/pulsein/ is lower the pulsein timeout or try another sensors. You can’t check and make sure the servo is geting enough current. I had to connect it directly to the battery th-cam.com/video/WBzBj73NXb8/w-d-xo.html check v2 out
@@JustBarran It seems like my sensor tends to lag at the set distance to trigger the motor. I think I’ll change my sensor, thank you for the suggestion.
Which sensor do you have? It might be one with a set knob ?
@@JustBarran I’m using 5V HC-SR04 Ultrasonic sensor
Yeah when you getting delayed serial output and the values or the values are large is because the sensor timed out
Can we give power for it using power bank
at 5v the servo worked well with the soap dispenser, but I needed a little bit more power for the hand sanitizer dispenser and I had to power the servo with 6v. Hope that helps. I think u can try the power bank.
Kinda sad you didn't show the waterproofing stuff, I guess you thought that was boring. What materials did you use for waterproofing, just the plastic container?
Hey sorry, it was a bit of a Oversight, was not planing to do that part of the video. But I used the plastic covers of some old 5 subject notebooks I had. And hot glued everything
Where will get the parts in this lockdown, only groceries and medical supplies are allowed through
I had these from previous projects. For now you might just have to wait. Or try to use what you have like I did .
What changes to the code do we have to make if we are using an IR sensor instead of ultrasonic sensor?
That depends on which IR sensor, if its a serial Ir sensor may have to decode/use a library to get the distance. If its a simple line break IR sensor, it may be a simple (digitalread(IR pin)==LOW) to trigger the servo. Hope this helps. I dont have any IR sensor module on hand but if you send the one you have I can see what I can do.
Please upload code for PIR sensor for automatic hand soap
@@ahmedawesome4406 I actually dont recommend using a PIR sensor since the sensitivity I usually really wide. If you still want to use it. I can put a code for you later but it would be a simple test on a digital pin, almost like a button press
Cool stuff
Thanks, I actually did a upgraded version to this so check it out when you get time th-cam.com/video/WBzBj73NXb8/w-d-xo.html
Nice, keep it up
Thanks bro 🙌🏽
Hi bro,,great work. im trying to make one but having a problem with the code,,its giving an error about this line if(distance
Hey, am so sorry. That suppose to be commented out. I added some comments because someone asked for it through git and I forgot to add "//". I made the change.
Thanks for pointing that out.
Hey man did you get through with the code?
bro congrats on 30k views
Thank you so much 😀
Very cool ! May I know what kind of wires did you use in this video ?
Normal 22awg hookup wires, I got a roll from Amazon amzn.to/3sZBkKg something like this. I also used a old USB cable to run the wire to the ultrasound sensor
th-cam.com/video/WBzBj73NXb8/w-d-xo.html version 2 of this project
@@JustBarran thank you ! Will it works if I replace it with Female-Female jumper wires ?
@@yunengtan3689 yea this is a very low current project so that would definitely work.
@@JustBarran Alright. Thank you for answering my question !
Video gôd chúc bạn thành công phát triển nha
cảm ơn
wow this is cool 👍 Do some more videos.
I have one in the works hopefully I can drop it this weekend.
I rather the semi-gloss I think It would have been classier. Good video tho bro
MasterBarran taught the same by I played it safe
Ready for “Shark Tank” bro.
JDRCustomlifestyle hahah am looking at you mark cuban
Hi, does the voltage determine how much a servo can turn? If so does that mean a 9V would have it turn more? I tried making this project but only a small amount of the hand sanitizer was coming out. PS thanks for the video.💥💥
Voltage determined how much torque can be applied. How much it can turn is determined by the manufacturer and the position feedback mechanism inside of the servo. There are 90 degrees, 180 degrees(typical), 270 degrees and 360 degrees servos. Also different hand sanitizers require more force to pull it down (sadly) as well as how thick the sanitizer is. If you using 9v I Suggest stepping it down to 6v with atlease 200mA that should give it enough torque if not you might need a bigger servo. Also make sure the string mechanisms moves smoothly on top of the dispenser. Any resistance would make the servos work that much harder. Hope this helps and let me know if you get it to work 🙌🏽👌🏾

Thanks a lot. Will let you know when I try. BTW did you connect the battery directly to the servo or to the arduino? I couldn't see clearly.
Maleek Shabazz I originally connected the battery to the Arduino and powered the servo from the 5v supply of the Arduino bit when I wasn’t getting enough power I, switch to a 7.2v lipo battery with a voltage checker (very important to have on a lipo) and powered the servo straight from the battery, they Arduino was also powered from this to ensure that the grounds are connected so that the servo and understand signals from the Arduino.
I understand. Please upload a schematic for this same connection.
What's the voltage of the lipo?
2s but a 9v battery could work if the soap dispenser is soft
It is believed that the sensor is already attached to your water tap,
Thanks for the video.
I wish it was :(
My servo is spinning crazy all time I dont know what to do...
what code/servo are you using
Can this be modified to dispense lube?? Asking for a friend XD
John Doe short answer is yes 😂 🙈 I guess this would help in self quarantine
