I am making an arduino project for a high school class that I teach and I can’t figure out why the voltage regulator on my uno keeps blowing.
I uploaded my diagram so you can take a look and see if there is an obvious error I am missing. It can be found here: http://fritzing.org/projects/arduino-bluetoothcar-with-obstacle-avoidance-senso
My current thoughts are the culprit could be:
- I need two seperate grounds, as opposed to a single common ground, though I don’t think this is causing the issue
- I was using an 11.1 V lipo, switching to a 7.4 could solve the issue
- I am drawing too much current through the regulator, not sure what to do to fix this
- I accidentally shorted something or made a mistake assembling my circuit, but I did have it functioning before the regulator melted.
Any assistance would be greatly appreciated.
