So, I recently acquired this RGB Led matrix but ,because I’m new to electronics, don’t know some stuff that i should.
I’m planning on driving this board using 4 74HC595 Shift registers and my Arduino uno (later on I’ ll try to switch it to an arduino nano)
My questions are:
- What resistor value do you guys suggest that i use to drive each set of colors?
- If the RGB LED matrix has different values for Red than for blue, should i use a different resistor value?
- I was planning on using a 5v power supply (the Arduino’s) but i can use a 9v, which one should i use?
I have attached the datasheet of the matrix (here is the link too). If more information is needed please let me know, Thanks!
