Dear All,
im trying to design a system whereby to open a valve using PWM. The only problem with this system is that, it require 2 different voltage levels with the same amount of duty cycle of the PWM. Here i attach as in the diagram below; The valve require 12v to open and remain to open it require just 3v. Can anyone please advise on how can i implement this. i know quite well on how to implement PWM either programmable or analog device but not with 2 voltage in single duty cycle. Please let me know if this is possible. thanks
