LED Water Level Circuit with ULN2003 - PCB Tutorial

[@Stefano91ste]

Hello =) Leave a LIKE! and if you missed it, this is my previous video about the LED Police Light: kzbin.info/www/bejne/hqXQdqSZh8eoatk

[@kissgabor2199]

Hi! I would need a PCB that is not 7-channel but 10-channel. I think two pieces of ULN2003 would be needed on the PCB. How and with what program could I modify the original plan?

[@sarvagnyapurohit9719]

Your channel is a gold mine! I loved your content!

[@Stefano91ste]

Thank you so much for appreciating my work :)

[@Kenjiro25]

Nice project, thank you for share :) Just one question, what maximum cable length does the integrated circuit support to be able to turn on the leds without problems?

[@robertgrlic6505]

What is the difference between unl2003A and unl2003L ?

[@CoquiAudio]

that is an interesting circuit bro I never thought of having a LED liquid level indicator cool man 😊

[@Stefano91ste]

Hi, thank you very much! in the past I also made a version of this circuit with transistors

[@powerupsuri355]

I have made my own using these components. # 433mhz RF module for wireless communication, # two arduino nano, # one HC-SR04 ultrasonic sensor to check water level in the tank, # one relay to actuate motor, # 16x2 lcd (i2c) it shows the percentage of water in the tank, # one touch sensor to turn-on motor, # rgb led to indicate water level, # two Hi-link SMPS to power both setups one in the tank and another near motor or wherever u want to place in the house.... #when i touch the surface of touch sensor motor turns-on when water level reaches 100% then motor turns-off automatically. I have been using it since last two months and its working perfectly. I also made it for my friend he is satisfied with that too

Hello there. I'm new to this but you make this look very easy. Could I ask you where I can buy 3 of these PCB's please? I'm in the UK. Thanks.

[@EneoRobertoOficial]

2003AN is 5V 2003A 6 to 15V

[@venkatram7497]

It for half an hour only, after that all less goes off. If I switch off and again on the circuit, leds giving just small blink and then turning off. Pls give a solution 

[@electronic7979]

Nice project

[@Stefano91ste]

Thank you :)

What about water electrolysis? I want to make a water level indicator for my bedroom evaporative humidifier.

[@mohammadkhalid6886]

Remove tank full top led and connect or contact parallel with 12v buzzer ,,,,, 👍

[@carlosmagnoguerra]

Hello! Thank you very much for your videos. I am Brazilian and I love your projects. Thanks for sharing the gerber. It's very nice. I am 54 years old, but I feel like a child with his projects. Obrigado

[@Stefano91ste]

Hi, thank you so much for appreciating my work! Obrigado!

[@EneoRobertoOficial]

Esse Ci tem fibal AN. Ele é de 5V de maxima de entrada. Os demais que são de 6 a 15V

[@علاءبيترو]

👍🏻👍🏻👍🏻👍🏻👍🏻👏👏👏👏

[@CrazyCoupleDIY]

You did not speak a word, but explained it well

[@Stefano91ste]

Thank you so much!

[@greyhnd001]

Can it work with a 9volt battery. If so how would the resisters change.

[@anoopm4465]

Dc volt ? , 9 volt led 2 working other not working

[@carlosmagnoguerra]

Hello my friend. How are you? Today the PCBs that I bought at JLPCB arrived. Very fast delivery, just two weeks. I loved the PDB´s. I bought VU meter, Led Thermomete, ULN_2003_water, Police Light. Everything very cheap. Thanks!

[@Stefano91ste]

Hi, thanks to you for appreciating my work :)

[@abdullah577]

Great job , thanks a lot for PCB file

[@Stefano91ste]

Thanks you for appreciating my work!

[@jorgepereira9898]

BUENOS DIAS GRACIAS POR COMPARTIR Y QUISIERA SABER COMO COMPRAR OENCARGAR EL CIRCUITO IMPRESO GRACIASSSS

[@dunghang1021]

I want to buy the complete set as above, where can I buy it?

[@Stefano91ste]

Hi, I share PCB gerber file, you can use it to order pcbs from manufacturers like JLCPCB

[@geniusarunesh]

is there a way to add a buzzer for tank full indication but should turn off automatically after duration like 2-3 min as water after filling will be there for quite sometime at full tank state

[@Stefano91ste]

Hi, a buzzer with a timer circuit should be added, which turns off the buzzer after a certain time

[@Elarpachuau]

Nice one. Can i use another resistor instead of 1k Ohm? Please reply me

[@Stefano91ste]

Hi, yes if it is a value close to 1K

[@Elarpachuau]

@@Stefano91ste I've already tested it, 1K resistor for LED and 10K for Tanky side wire is best for this circuit... Thanks for reply by the way

[@CarlosFlores-wn1xt]

hello what program do you use to make your circuits example proteus, fritzing

[@Stefano91ste]

Hello, i use Sprint Layout 6.0

[@joseriverjr6720]

Hi there! I need 4 of them, can you sale does to the public?

[@Stefano91ste]

Hi, I don't sell PCBs, I shared the gerber file in video description

[@jumbo999614]

What is resistor value if I'm going to use 3mm led?

[@Stefano91ste]

Hi, use the same 1 Kohm resistors :)

[@anoopm4465]

not working in water

[@hemantkumar.23]

Can I use this overhead tank 25 ft

[@Stefano91ste]

Yes you can

[@sandeepgupta6526]

I want blank PCB for this project.

[@Stefano91ste]

You can order it on JLCPCB using the gerber file I shared in video description

Does anyone out there have a board for sale?

[@Stefano91ste]

Hi, you can download the PCB files from the video description and buy the boards on the JLCPCB website

[@munyratanakbr]

Can we read as digital value from this IC to microcontroller?

[@Stefano91ste]

Hi, no only analog signal

[@munyratanakbr]

@@Stefano91ste I might can catch only HIGH _LOW from this? Isn't it?

[@lk-zy4do]

[@josejimenez8166]

hello. i would like to buy this pcb. how can i do it

[@Stefano91ste]

Hi, you can download the pcb file from the description of this video and order the pcb on JLCPCB, in the video I show the whole procedure.

[@srilanka82]

Did you check it With the distance of over head tank and ground level ?

[@Stefano91ste]

Hi, I didn't understand the question, but in a 2 meter high tank it works fine.. with higher heights it should work but I can't guarantee it.

[@nimalperera5454]

No.problem about the height.

[@brianmcdonald4805]

Che misure sono del pcb? Sull'ordine bisogna inserirle?

[@Stefano91ste]

Ciao, no una volta caricato il file il sito riconosce le misure, ad ogni modo sono meno di 10x10 cm in modo da restare nel range per l’offerta dei 2$

[@brianmcdonald4805]

@@Stefano91ste grazie stefano .......gentilissimo.Ti chiedo una cosa, volendo inserire un sensore di rilevamento ad ultrasuoni ( per evitare corrosione fili a lungo termine), c'e la possibilità di farlo?

[@stormbytes]

Do you have any of these for sale?

[@Stefano91ste]

No, I don't have any more, but you can order as many as you want from jlcpcb, in video description you can find the gerber files for this PCB

[@greyhnd001]

Can you do it with 5 volts?

[@Stefano91ste]

Yes, but with transistor like this: kzbin.info/www/bejne/jnyqpZqYiJaCrNk
