Sooo, I've fried something, and I'm not sure what it is or how I did it!
Can anyone enlighten me?
I've stared at the schematic provided by arduino but I can't make sense of it..
Picture of the board below, I've fried the little black component behind the power plug..
Powering the arduino with 9v, drives two servos, and is hooked up to a motor driver with two geared motors powered seperately, the arduino also has the Dagu compound eye hooked up to it.
Anyone have any clue what I have done wrong/what I have fried and how?!
From looking at …
http://arduino.cc/en/uploads/Main/ArduinoUno_R3_Front.jpg I would say it is a surface mount diode labeled M7 (on the diode body, not on the board.)
I looked at the schematic and D1, up near the power supply section is in fact labeled M7.
I would go way out on a limb and say you reversed your polarity in a big way.
I’m going to have to admit
I’m going to have to admit to having done this now…
soldered a bridge and the board’s working again, have also labeled my wires, so I am less likely to refry my beans.
Thanks for solving the mistery though
