I thought I could drive up to a maximum of 6 RGB LEDS. So, RGB1 D0-D2, RGB2 D3-D5, RGB3 A0-A2, RGB4 A3-A5, RGB5 A6/A7/RX, RGB6 D6/D7/TX. This doesn’t seem to be working… Am I missing something?
In the end, I’d like to drive 6 RGBs… Any ideas/help?
There are only 9pins and only 7 of these can be used independently.
If you just want to HIGH/LOW the LEDs you can connect more LEDs but are stuck with max. 125mA over all of them, unless you use extra drivers.
A good alternative are NeoPixels, which only require one digital pin and will allow you to control hundreds.
