Powering Arduino and L293D with the same Power Supply I am relatively new to Arduino and plan to power an Arduino and an L293D Motor Driver with the same 9V power supply as in the diagram below.
I tried to simulate this with Tinkercad, but it seems like Tinkercad always powers the Arduino with an extra USB Cable, so I can't test it with only 1 power supply.
Would the 9V battery power both the Arduino and the L293D in this example?
I don't see any problem. You used the Vin for 9V, and shared grounds.
I suggest using a bypass capacitor (typically 0.1 uF) for the L293D VCC, but I don't have experience with using a L293D.
Also, you need to check if the battery can deliver enough current for both motors and the Arduino.
