How to create custom PCB for your Arduino Project Part2 -Soldering components and testing

- In my previous video I provided a Fritzing application tutorial, showing how you can design and order a custom PCB for your Arduino projects.
I ordered a printed circuit board which would make a module with integrated 7 segment display controlled by shift register.
The PCBs have just arrived from China and this is a follow up video that will show unboxing, soldering components and running some sample code to prove that the module we created works
I have an isse with email account I created for the purpose of the competition.

There is nothing cooler than designing, then wiring and testing, your own PCBs. Nice job!
Especially if it works:)
Nice work and nice of you to give the extra PCBs away.
Thank you
What I would find interesting since the Arduino is a prototyping board. What would be the steps to "replace" the Arduino if you were to do a production ready product. I'm a modeler and don't want to use an Arduino in every model for blinking patterns. Could you do a video about that?
On my list to do :)
Hey Mario, Greetings from India - I added a third digit, connected the overflow of the second shift register to the data pin of the third shift register. Added the latch and clock pins in parallel to that of the first and second shift register along with the power supply to the digit. Tweaked the arduino code to count upto 999. The third digit (LSB) is erratic. replaced the third digit, suspecting the 7 segment CA type LED display to be faulty, no improvement. Could it possibly be the current consumption (sourcing from the shift register) thats limiting the count, I am using 220E resistors, shouId I attempt 330E resistors to decrease the current from 13 mA to 5 mA? Have you tried adding a third digit? Looking forward to hearing from you.
I did not link three digits. It can be linked to the current consumption. You can test it by powering the shift registers from external 5v power supply.
Can you make one for a 4 digit seven segment timer display ??
You can but there are better ways for controlling 7 7seg displays . Check ruclips.net/video/IiWhnIhf-uU/видео.html and ruclips.net/video/ux3cpw0nHo4/видео.html you can even buy ready to use 4 digit module with muilt in MAX7219 chip pl.aliexpress.com/item/1005005403447240.html
Cant you have the arduino part on the PCB board as well?
Sure you can. This was just a simple project to show how to use fritzing. If you check the other project of mine you will see more complex PCB which I would use to build a custom 7 seg clock. ruclips.net/video/ux3cpw0nHo4/видео.html . Here you will see that I plug in Arduino onto the custom PCB
@@marios_ideas thanks.
