did I destroy my arduino mega and ramps 1.4? Answered
I was using an arduino mega and ramps 1.4 motor controller for my 3d printer.During the time of testing ,i switched the power polarities in the ramps 1.4 , then I put 12V in the arduino then the mega chip got hot.
This is the state now,when i plug the mega on to my computer :
1)The red ON led lights up and the L lights up.
2)device not detected.
3)Reset button does not make any change.
4)RX-TX lighting up.
when i plug the 12 in the ramps:
1) the red ON led lights up, the green doesn't
I want to know if this arduino and the ramps 1.4 can ever be used again.
thanks in advance!!
