I have an o/p voltage of 0 to 5vdc from the throttle pot on my car. I need to somehow only switch a relay when it is 4.5v or above, and then release again when it drops below.
It doesnt need to switch any power. Help please, mark

Hi,

No need a Pic here !!!

a simple LM393 comparator or a "741" OPA should do the job...
