Hello, I am new to arduino, this is my first project
Here's a sketch of the circuit. I am using 6 AA batteries ( couldn't find 6 AA batteries in Fritzing) to power a L298N and from the 5v pin I power the arduino.
Why isn't the HC-05 powering up? I thought maybe the arduino isn't providing enough voltage but on the back of the BT module says 3.6-6v so I don't think that's the issue.
First is the 5V jumper on the module in place? Without it you have no 5V output.
Then it looks like you're connecting the 5V from the L298 to Vin on the UNO which needs at least 7V because it goes through a regulator. Try connecting to the Uno 5V pin - that's the one that can take 5V.
If I plug the 5v output of the L298 in arduino's 5v where should I put the bt module? Can I plug the bt module directly to the 5v output of the motor driver?
