I am trying to use the Adafruit Metro Mini as Arduino (can be used the same way) to program an IR Break Beam sensor and a stepper motor. I connected the beam sensor to the breadboard and plugged the Arduino into my computer. But my MAC pops up with the notification:
"USB Device Disabled - Unplug the device using too much power to re-enable USB Devices."
What is the problem causing the issue? Did I short circuit something? I attached photos to my circuit to the post.
Thanks so much in advance.
