Arduino Based Liquid Filling Machine | DIY Bottle Filling Machine | DIY Electronic Liquid Dispenser

[@walangsungsang7296]

very cool sir....this is what i've been waiting for.but maybe it's better that the last video scale that used a keypad...modified as a filling machine

[@diy_electronics]

Thank you very much 😊😊 Study both codes. Then you will be able to modify it as your wish.

Help liquid dispenser. ino: 6:10:fatal error :hx711.h:no such file or directory

[@Ashraf_aim]

Sir in the video at 8:28 i seen some wires back of the pcb please explain it sir

[@diy_electronics]

In my first PCB, there was an error and I fixed it with external wires. But I uploaded the corrected PCB with the drive link in the description. Thank you.

[@Ashraf_aim]

Thanks sir

[@sridharkrishnappanavanerth3388]

Very good video sir, but please make audio video at very step so that we can understand your tips and tricks.

[@diy_electronics]

😊👍

Nice Project bro . How to change the code to show weight window all the time so that we can see the actual real time weight .

[@StarlordYtSurya]

Bro how to tare load is tha auto tare

[@diy_electronics]

scale.tare(); is the code line that used. Before use it, you have to include "HX711.h" library also.

[@abdulabdulrahman3871]

thank you very much for this sir. pls sir how can i get the parts? whats the name of the lcd type?

[@StarlordYtSurya]

Bro can i extend quantity to 4kg plz explain

[@diy_electronics]

In this video, I used 5 kg load cell. So you can measure up to 5 kg. First line of the void loop function, I selected the minimum weight 50g and maximum as 500g (weight in grams = volume in milliliters). You can change maximum value as 4000 for your case. Thank you.

[@rajivgaur2729]

Bro can I use 20kg load cell instead of 5kg load cell..Pl replay

[@diy_electronics]

Definitely.

[@sayedhussaini4894]

How to include hx711.h library and liquid crystal i2c library.. please send links of libraries. And Please help to add tare button

[@diy_electronics]

Libraries are uploaded. Sorry for the delay.

[@sayedhussaini4894]

@@diy_electronics but there is no links available in the video discription for libraries

[@diy_electronics]

@@sayedhussaini4894 Now it's ok. Previously I only updated them in the Arduino Scale making video.

Wat is cost of this project

[@buskuya]

Can you please add an Gerber file of pcb

[@diy_electronics]

I did this project with the Eagle software. Eagle files are now available at the PCB link in the description.

[@khastriadl]

where is the arduino code bro..can't be accessed directly to the arduino application on a PC, it's just in the form of a Zip..

[@diy_electronics]

Unzip the folder

[@khastriadl]

@@diy_electronics ok

[@khastriadl]

can you make a filling machine using a water plow... thank you

[@shuvradey1490]

Sir I want to make gel liquid machine like this, it is possible sir?

[@diy_electronics]

It is possible. But you should use a better gel filling mechanism instead of this pump.

[@shuvradey1490]

@@diy_electronics sir please tell me which mechanism suitable for gel filling machine.

[@diy_electronics]

@@shuvradey1490 Using a compressed air system will make it possible.

[@StarlordYtSurya]

Bro plz explain clearly about circuit diagram

[@diy_electronics]

Of course. In the schematic diagram, the LCD with I2C should be connected to the SDA and SCL pins on the Arduino. So they are connected to A4 and A5 respectively. The middle pin of the variable resistor should be connected to any analog input pin. Here, it is connected to the A2 pin. Both the buzzer and the relay should have one of their pins connected to any digital pin and the other pin to ground. Here the digital pins are connected to D11 and D2 respectively. One pin of the push button is connected to the digital pin (D8) and the other pin should be grounded. No external pull-up or pull-down resistors are needed because the internal pull-up resistor is enabled through the Arduino code. The HX711 is an analog to digital converter (ADC) that is used to convert analog voltages coming from the load cell into digital signals. DT and SCK pins are connected to A1 and A0 pins respectively on the Arduino. All VCC and GND pins should be connected to Arduino's 5V and GND pins respectively. The 5V power supply is connected to the 5V pin of the Arduino. Please refer to the schematic diagram (Link in the description). Thank you.

@@diy_electronics bro one more request plz explain about which value change for 0 to 10kg set point by poteionmeter

[@StarlordYtSurya]

Ur project only for 500 ml maximum,but i need to modify for 10kg set point plz tell me which value change for 10kg

[@diy_electronics]

Here I'm using a 5 kg load cell. You have to replace it by 10 kg load cell. In the code, there is a line (line 51) including a map function. Its, value 50 represent the minimum value and 500 represent the maximum value. You can change them as your wish.
