I beg for your knowledge of electricity in order to sort out the following problem.
What I have:
- 1m strip of WS2813 - 60 LEDs total
- FEZ Panda2 to send the signal to basically light all the LEDs
- The 1000 µF, 6.3V capacitor is added between + and - of the power supply outputs as it’s stated here:
So, when I use a 4.5V 0.5A 6W wall adapter from my old Panasonic CD player I am able to make the whole strip lit with no problems.
However, my final project needs about 600 LEDs and I’ve decided to buy a much larger power supply. Here’s basically it:
As you see it’s 5V 40A 200W. Since I don’t have 600 LEDs right now I’ve decided to test it with the same LED strip as above. As a result only 2 or 3 LEDs lit with some random colors. When I switch the power supply back to the smallest one - everything is fine again.
Do you know the reason for this mystery?
