Topic: Orange light, is a problem= (Read 4857 times) previous topic - next topic


Hi! I'm new with Arduino. I bought an Arduino Mega 2560. I'm using Ubuntu 12.10. I've connected Arduino using an USB cable. In a tutorial I've read on Internet it says I should get an orange light blink and then a green light. The problem is when I connect the USB cable the orange light never dissapears.

I mean, I get the orange light blink, and I get the green light. But after the blink the orange light stays turned on. Is that a problem? Should I worry? I dont want to keep on with the tutorials because I'm afraid of damaging my Arduino or my notebook.

Sorry for my bad english. I hope someone can understand me :P.

That is what mine does and it works perfectly.
Please post technical questions on the forum, not by personal message. Thanks!

If by orange light you mean the led on pin 13, mine's often on too. I suppose it's the arbitrary condition of the pin?

Pin 13's led being on all the time does annoy me though, so I often just throw a line into setup to force it low.... saving a few nanoJoules of energy and thus doing my bit for the planet  8)
