ATMega328P MCU + ATMega8U2 USB Controller
Compatible to Arduino UNO 2011
Key Features:
ATmega328 Microcontroller
Bootloader installed, ready to upload programs (sketches) from Arduino IDE (software)
Flash Memory 32 KB
EEPROM 1 KB
I have tried on both Windows XP and Windows 7. I see the COM Port in device manager when plugged in.
So I select Com 5 or Com 3 depending on PC or notebook I have tried it on. When I plug it in, the Yellow LED Pin 13 always flashes.
I have tried selecting different board versions(Deuminalove w/AT328P). The Upload looks successful, it says Done uploading...
There is a number 1 bottom left corner of the screen, does that mean upload is good?
Even I tried the on board reset nothing happens.
All I'm doing is modifying the blink sketch, resave it, comment out the LED High so I don't see it blink anymore,
this way I know it's functional. I have tried Pin 9 and Pin 11, digital, it's always 0V.
I thought this thing was suppose to be simple to use!!!
here is the code. I just changed the Blink sketch pin from 13 to pin 8. I always measure 0V though.
Thank you for your help! Can't wait to get this moving along.
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 8;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

I tried several different things to confirm if it is functional.
I added comment to take out the LED High with the original Pin 13. The LED still keeps flashing when is should be off.
I then restored the blink file so it turns the LED High and Low. All I changed was Pin 13 to Pins 8,9,11.
I measured the digital pins at 8,9, or 11 with the volt meter, it's always around .2V
I get this message when no board is connected after upload

Sorry for the confusion. I had initial troubles with windows detecting the uno. I read somewhere, on this forum or another
to download the self executable which has the USB drivers built in. The file is: setup_Arduino_ERW_1.0.1f_20120912.exe
After install, it detects the uno at least.
If i use the ERW IDE, I don't get the red communication error message, only in the standard IDE.
I tried further steps. I uninstalled the Enhanced ERW IDE. I uninstalled the USB drivers.
I plugged the UNO back in, it asked for drivers, I pointed it to the 1.0.1 drivers. It installed the drivers and shows up as
COM5 in device manager. Attached capture shows driver installation successful.
When I upload, I still get in red text:

avrdude done. Thank you.
Previous posts say this is user error, wrong drivers, etc.. I don't know what else to check at this point.

What board type are you selecting? With a Uno I would select the Uno board type.
It's possible your Uno does not have a bootloader installed, especially if you got it second hand, or not from an official supplier. This is hard to check with only one Uno there. You could get a ISP device (for around $20) which lets you upload the bootloader if it isn't there.
I googled the error message: avrdude: Send: 0 [30] [20]
Other forums they found a pretty consistent fix.
For whatever reason, it does NOT work on COM5!
I changed it to COM9 like the other members and now it works just fine!
That was simple but sure took a long time to dig through.
I'm certainly going to be post back later since I really suck at code so
will need some help. I've taken C+ class before but I'm just not wired for software.
