Maxmsp - Arduino

Hello. I have looking around 3 hours about Maxuino. How reliable is this? It seems mostly uses to send simple number datas, but does hardware just work as Max tells so?

Simplemessage works, but not digitalwrite. any step by step tutorial for Maxuino? it is just so not enough.

I need is PWM data from sensor to control big lighting(not 2~4 LEDs). Is it enough to just using Maxuino or need more hardwares?
