Hello, I finished the driver. I share here the final result. except the case, that is not finished. The jumper allows to run in tow modes: 1. Arduino controlled (will work always in this mode). 2. always ON. Regards. By the way, this is my first circuit!!!

Hello, thank you booth for you explanations. I have already made driver based on the LM317, so cannot use the solution by Bionic-Badger. But it was interesting for a future. Finally I'm working with the circuit in the picture. I think that now is as teached by Mr Things. I can finally switch...

Hello, Thanks for your answer! If I connect like in the picture, is there somenthing wrong? I have tested with leds and it binks as expected, but I'm not sure if I'm making in the bad way. Thanks again. Regards.
