I am currently doing a project and it seems that I may have blown my Arduino Nano (or maybe not). The power LED of the Nano was still on and I believe the L pin blinks once every time I press the reset button.
I wanted to use 4AA alkaline batteries to power my project. The servo is a continuous servo rated for 4-6V and 15-200mA from Parallax. Given that the Nano runs optimally when powered at 7-12V, I decided to buy a step-up converter (adjustable output voltage). It looks like this although I bought it elsewhere:
When I tried to test it with the servo running, my Nano stopped working after several seconds later. Did I wire them up wrongly? I also measured the output of the step-up converter when it was running with a voltmeter between the two terminals of the step-up's output. Would it be possible to short it that way?
Appreciate any help I can get. Thanks
