one more thing, I am going to order arduino DUE board..the reason is that its 32 bit (all those PWM,adc etc)and has inbuilt DAC(which I need most).
so, any suggestions on that or any improvements and as I am working with AC(230v/50hz) supply and power factor correction stuff ,I need to buy voltage and current sensors, any preferred brand or website for those sensors.
thanks a lot for ur help 8) 8)
