Arduino board details:
Arduino Uno R3(Original),
Made in Italy.
PC OS is Windows 8.1,
Arduino IDE ver. :1.6.5.
A code which uses IR Sensors (required for line following robot) was uploaded onto arduino.
The arduino with the code on it worked fine but it did not allow further uploading of any code.
I tried ‘reset’ button but it didn’t work. In fact it just restarted the code from beginning.
And the error during uploading is:
avrdude: ser_open(): can’t open device “\.\COM3”: The system cannot find the file specified.
I think it may be due to the code that is running on arduino (executing loop() function ) engaging the board and not allowing further uploads.
I have already made sure that i have been using the correct COM port. I also have the required drivers installed on my PC.
Awaiting any suggestions or fixes to this problem…
and of course Thanks in advance.
