So I should start by saying hello.
I bought a Mega 2560 and was instantly hooked! I've been playing with it for a few weeks now and decided to build a balancing robot.
I received a H bridge motor driver last night and finally got a chance to try it out tonight. My recycled ATX PC power supply that I usually use is under modifications, so I decided to use the 12vdc SLC battery that I plan to power the robot with to test the H driver board out with and connected it to the Vin and GND pins.
Long story short...
I decided to use the 5vdc provided by the mega for a pot and a switch and accidentally connected it to the same rail on my breadboard that the 12vdc from the SLA was connected to... damnit...
It was probably only connected for a few seconds before I saw light dim and realized what I did and yanked the wires. Now the tx/rx lights are always on and the Atmel chip gets HOT fast if I even plug it in to USB... Am I screwed? Is this going to be a seriously expensive hobby if I keep doing this late night while having a few drinks!? HELP!
Thanks,
Steve
