Hi,
What i'm trying to build is a controller that once triggered will vary the pulse width to a solenoid from 20% to 100% (so in effect open a little to fully open), over a variable peroid of time, say 1-10 seconds.
A high power transistor like a TIP122 will be needed to run the solenoid, but that is about all I know! lol
Can anyone help me with this?
Many thanks!
Karl.
