Hello everyone :)
For a remote control application I'm using an HC-05 Bluetooth module. Since the remote has no on/off switch I want to be able to cut power from the module before setting the arduino to sleep.
I thought it should be no problem to power the module by digitalPin 11, but when I do so, the voltage reaches only about 2,2V.
I'm using an arduino Pro Mini which should be able to deliver 40mA per Pin. I was told the HC-05 takes 35mA max.
Unfortunately I cannot measure the current, because the case of the remote sits a LITTLE bit tighter than planned :D
I hope to find a solution without another extra transistor, since another piece of wire and TO92 would hardly find any place :P
