Hello,
I did some googling on this but I'm not even sure if I have my nomenclature correct.
What I would like to do, is control 4 RGB LEDs using I2C from an Arduino Nano because I cannot spare 12 pins just for LED control. I don't need the IC to do any PWM at all, just being able to send it commands over I2C to set pins high or low would be sufficient.
Does anyone know if such a chip even exists? Obviously, it wouldn't be a chip specifically designed for LEDs, it would just be a chip that is capable of having pins set high or low based on whatever I2C command is sent to it. Not sure what you would even call such a chip, but I could really use one.
Thank you,
Mike Sims
