Here's one of those very basic questions, I prefer to admit I'm ignorant instead of making a mistake I'll regret all my life.
I'm using Arduino UNO to interface it with an accelerometer and a bluetooth module. The accelerometer is fed by the 3.3V pin from the Arduino but the bluetooth module also needs 3.3V in order to work. Can I use the same 3.3V pin to power both the accelerometer and the module or should I use the 5V pin for one and the 3.3V pin for the other?
Then on the 5V pin I would have to use a voltage divider so I can only take 3.3V, right?
Thanks.
