It happens!LOL thanks! the 10mA is a Typo...i hate when i do that. The specs for the red LED are: 5mm 2.6v - 28mA
sorry about that.
Those are the specs printed in the bag of the LEDs.Red LEDs are not more than 2.2V so your 2.6V odd-ball is wrong.
That's fine. I want them to be a bit dim anyways.The key to the whole thing is the 62 Ohm resistor. This will cause the regulator to put out 20mA (nominally).
Im no expert...but i guess if you hook up a potentiometer...so is it possible to make a current adjustable and voltage adjustable RPS using a single LM317?
No. It's an either/or proposition.so is it possible to make a current adjustable and voltage adjustable RPS using a single LM317?
