Hi, I'm a new member so until I get the hang of this I hope to make myself understood. I have to make a small circuit/device to patch between two electronic device's.At the control side (input) I have voltage rising from 0volts to 5volts max. on the output side I have a device expecting 10volts falling to zero. There is another control option, a heat source that rises with the input voltage no temps to supply at the moment. Any ideas, cheers.
