Some facts: Each 5x5 panel draws about 350mA,...... The battery can output up to 2A, so I don't think it's a problem at this stage.
What is the maximum current I can draw through the 5V output on the Arduino?
What is causing the flickering when powered through the DC-DC booster?
Am I doing something fundamentally wrong with my set up?
However, the battery is rated at 2A
So it is likely that the flickering is due to high current
Would a resistor help?
For my physical computing art project
I note that there are several large capacitors on the DC-DC converter which should be doing the job?
of the oscilloscope connected across the LEDs
to no effect, except the noise is less loud.
Could it be something to do with the SPI interface not being in sync somehow?
