Hello all, I am running Windows 7, 64-bit Home Premium edition using an Arduino UNO SMD Edition board for my senior project. I had my arduino board connected via USB (COM3, as assigned by the computer) as well as having a 10 VDC power supply connected to it as well (since for my senior project I have to run the board independent of a computer). I was using the VIN input to power one half of my breadboard (to power a 6V DC hobby motor) and using the 5V input to power the other half (to power the logic chips that I have connected). It was working fine (I was just doing some preliminary checks on the logic chips and on the inputs and outputs to/from the board before I would connect the motor. While I was trying to compile my code and upload it (was working fine before). this error came out:
avrdude: stk500_getsync(): not in sync: resp=0x00
I've read all the previous Forums as well as the ones from the old Forum block but those all talk about previous versions of the Arduino. I've tried pressing (and also holding) the RESET button but nothing happens, and I've also tried pressing the RESET button right after the "Binary Sketch Size" thing shows up, and still nothing. I've also restarted the program, changed the Serial input to (COM1 and after to COM5) I've also tried uploading the program with the Programmer and it gives this error:
avrdude: usbdev_open(): did not find any USB device "usb"
The programmer I'm using is the AVRISP mkII. When I upload a program the only one that seems to respond from the 3 LED's that should light up is the RX. Ive tried tying the RX and TX pins together to see if that will work and the TX blinks with the RX but I get the same error. Is there a way to reset or to FIX this problem? or has the processor fried? I've ran out of things to do, I NEED HELP!!! It doesn't make sense to me, I didn't accidentally tie anything to the power pins or input and output pins and I made sure that the range of Voltage that the Arduino board can handle were proper. HELP? I would really appreciate it.
