Connect my led strips (12v) to arduino

[DrDiettrich]

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.  

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

As stated a few times already, yes.

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.
