You could do a quality check on all items, including power supplies, but I fear that you can't do that :-(

Why aren't you  using TPIC6B595 for the segments? One shift register per digit, vs 2 chips. No problem driving 9 LED strips either.

Here's a board I offer that will drive 12 digits, driving 3 and 6 LED strips

CrossRoad, Tpic6b595 Can replace uln2803 + 74hc595 ?

This is my circuit :


What do you think ?

Not "can", absolutely should!

OP did already get that advice 45 posts ago, and ignored it.

Sometimes, in the process of learning, repetition helps.  :smiley-cool:

Used to be very popular in primary school, not so sure what they do nowadays. :smiley-eek:

Thanks and sorry guys, this is my first arduino project and there is too much information, I can't assimilate all of these info :)

Keep in touch, I'll come back to show you my project

It works well for 1 hour and then... boom
Was that a one-time event?  Could be a coincidence.
