I purchased an Arduino Uno a couple months back and had no troubles getting everything installed and running properly as it should. I recently bought this 2nd Arduino Uno, a little different from my first:
I plugged it into my USB. The board lights up, seems they already have the “Blink” sketch loaded as the I/0 13 onboard LED is flashing as well as the “On” LED.
I have done everything I did with my first Uno board to get it installed, and for one I can’t seem to get the device manager to read “Arduino Uno” instead of just “USB Serial CH340 (COM5)”. When I try the “drivers” folder as suggested in the guide, it says “Windows has determined the drivers for the device are up to date”
I can’t get sketches to load, I have tried the “fade” example, and a few others and the sketch loads almost to 90% then a long pause and then says:
“Wrong microcontroller found”,
“avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.”
I have checked this in Tools (it is set to Arduino UNO, I also tried a few other boards as well) and the serial port is set appropriately to COM5.
But plugging in my first Arduino board with the same USB cable still works flawlessly…
