Dimming can be done by an analog voltage (20%-100% of max current by varying voltage from .5V-2.5V) or by PWM (so long as PWM minimum voltage is less than .4V and can work for 12-18pcs 3W led chip n series connection. I know it's doable at first but assume the slight differences in leds eventually cause problems which cause some parallel strings to consume more current than the others, till, eventually, some

Led Drivers Explained

You can use the PWM signal from an Arduino or your favorite microcontroller to dim each channel individually, or you can tie them all to the same PWM for simultaneous dimming. In most applications using a low voltage DC input LED driver is recommended. It's the Arduino Pro Mini!
