1  Using Arduino / Installation & Troubleshooting / Re: uploading code on arduino uno on: February 27, 2013, 05:20:39 pm
Nvm I found my problem it appears to be the usb port as it is a bit finicky with my mouse and it looks like the same for the arduino, switched ports and it works fine. I did not think it was the port at first as it never came up with the error of "wrong com" or anything like that.
thanks for your help though

Alright, i did that what should i be looking for, or not looking for?

I just started to get the error of
avrdude: stk500_getsync(): not in sync: resp=0x00
I'm not sure what that means or how i should proceed to fix it.

Ah! that makes sense, i cant believe i forgot to simply complete the circuit. Thank you

Once buying some servos i simply used the sweep example to get the range of degrees. While testing this part i had simply just plugged it directly into the board of 5V. However i need the higher torque that comes with the higher voltage, 7V. So i hooked it up to a power supply i had. Upon doing this with the simple sweep program the servo failed to run, and every so often jerked about randomly. So i tried using a couple of different batteries but the same thing happened. I though maybe i messed up the servo in the process so i plunged it back into the board, it works perfectly there.
I do have a wall plug for the ardunio, and i do know about the vin pin that it is the power before going through the voltage regulator, for like a 9V battery. But i really don't want to be plugging in all the servos into the ardunio as with 4-5 servo being plugged in i believe it would just drain the power from other important parts of the board.
I don't know what i'm missing here, maybe i need a diode or a capacitor  to regulate the power flow, or maybe its the servos themselves, which means this is never going to work.
6  Using Arduino / Installation & Troubleshooting / downloading issues on: February 17, 2013, 02:59:13 pm
I've had my arduino uno for a couple of months but then just today it quit allowing me to download any new programs on it. In the bottom right it says ardunio on com 3, but under tools/serial port is completely grayed out. I know that i did not blow anything as the last program on it still works. I checked the drivers, and they are up to date. I am stuck at this point trying to figure out what to do next.
