@blazecoding2009 actually I have used net labels there so all the leds are connected to the 555 , I would be really grateful if you could review the PCB once as this is my first time and I don't know wheather it's correct or not I posted it in #electronics also but no one responded there

In the schematic, I don't see it connected to VCC/3.3v

But they are connected to the out pin(3) of the NE555P doesn't that supplies the current to it? Also please refer to the PCB also once 🙏

It does but you need a positive and negative connection to the LEDS

@LimesKey would you mind double checking for me if I'm correct here?

Looks okay in the Gerber view but the schematic is wrong like what @blazecoding2009 said. Can I ask why your LEDs are THT and so large? I think your PCB should work but some of the design decisions you did are interesting.

Also that, smd would be a better option and would look a bit better in my opinion. Tht usually Is also more pricey for PCBA

This was really my first time creating a full PCB design so I also don't know what I did but I just did it I selected THT because with the SMT I was facing issue with the bottom copper layer 🥲 Please share your thoughts and suggestions so that I could incorporate them. For the LED connection I wanted to connect all the leds one end to the out (3) so I searched how can I do it and then choice net labels, if there's something I need to change in it please let me know.

I was facing problem with the back layer and when I switched it worked pretty well that's why I choice it, if its possible with smt could you please share any tutorial or project with it. Then I would change it to SMT

SMD is the same as THT, just want to say that it's okay to have positive and negative on the same layer

But while creating the routes they were contradicting. I'll try once again today with SMT 👍

Try using vias! You should seen an optoin

Thank you I'm currently a bit busy due to some assignments but I'll do it soon 👍

@blazecoding2009 Could you please help me out by confirming if everything is right this is my schematic so that I could move on to the pcb. Here's a 3d img also on the pcb, looking forward to your feedbacks. Schematic_heart_sim_2024-08-19 (1)
