Hi , i recently make a project by using Arduino Uno and L932D Motor Controller IC in order to control my motor that can reverse its polarity only with bluetooth .
My problem is , my arduino is running on 5V supply and its max output is only 5v . What do i need to add on my circuit in order to get 12V power that can be reversible ?.
I attached a schematic diagram for your guidance .
Thanks . Sorry for bad english
Remember that you cannot go above 5v on any pin of the Arduino. Therefore you need to separate the supply Vcc for the Arduino from the voltage supplied to the motor driver. The Gnd must remain connected.
The 12v can be used to feed a 5v regulator to power the Arduino.
Look at the data sheet for the driver and it will show where to connect the 12v to the driver.

And always double check the wiring before powering up - make a mistake with 12V and
your Arduino is toast.
