I'd like to power a nRF24L01+ wireless module by using an output pin, so I can switch the wireless module on and off through code.
The issue is that the nRF24L01+ wireless module runs on 3.3v, and the output pin of my Arduino Uno gives 5v. So my question: is it possible to bring down the power of the output pin down to 3.3v? I know this can be done with a voltage regulator, but I don't have one right now. So maybe this is possible with a basic resistor? (as an interim solution)
