I have 97 LEDs soldered on to a stripboard in rows. Each row has varying lengths and I have no idea how to power the whole sign at once.
I tried powering 28 LEDs across two rows using a 9 volts (I was going to use a 9V battery but the bench power supply seemed more forgiving if I do something wrong) on a bench power supply connected to a buck converter. When I powered the circuit, the LM2596 chip on the buck converter went bang!
I was able to use this set up to power short strings on 4 LEDs but I would like to power the whole thing at once.
How would I power this board? Should I be using a buck converter, should I use something else and is there any way to power the all the LEDs with a battery.
I was trying to follow a tutorial on YouTube (The tutorial by Great Scott I tried following) but didn't know how to connect the LEDs
I used this Buck converter module https://www.amazon.com/gp/product/B008BHB4L8/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B008BHB4L8&linkCode=as2&tag=gre09a-20&linkId=4YLLYWHFS3V7EXZM
