LED driver with PWM dimming

Projects General Guidance

Hello all!

I am new on this forum and with arduino.

I'm making a dimmable led light.

I ordered a LED driver which supports PWM dimming.

My question is:

Can I control several drivers with one pin or I need to connect them separately (one pin one driver)?

Thank you.

Probably, but we can't be sure unless you post the circuit diagram.

I would prefer a PCA9685 breakout board over the coarse 8-bit PWM from an Arduino.
16 channels of 12-bit PWM, controlled with a 2-wire bus.
Available from Adafruit or ebay for a few dollars.

I don't have a circuit diagram.

I will look in to that board you suggested. It looks promising.

Thank you.
