So I am in Science Olympiad and I am doing a project called robot tour where the robot is autonomous and goes around a track. so anyway I am trying to power a breadboard from the Arduino board. so i have 6 AA batteries powering a motor control module and my Arduino board through the Vin and GND pins but when I plug my breadboard into the other 5V and GND pins, the light on my board turns off.
What are some alternative ways to power my Arduino board or breadboard that don't cause this problem or cause a short circuit?
This is the wiring diagram that I am using.
the only difference is that I am powering my board through the Vin and GND pins rather than the power jack.
and here are some pictures of my project
Hi Maurice, please post your wiring diagram here on the forum. No need to make other forum members click on potentially risky links posted by someone we don't know. Better still, post a schematic.
You make a very common mistake. Powering any Arduino via Vin makes it No, No to power almost everything from the Arduino 5, or 3.3 volt. The onboard converter will overheat and might get damaged.
The general rule is that no Arduino can be used as a power supply.
