Arduino Nano v.3 Connection issue

1

I Have Just purchased the Arduino nano v.3 and Wanted to try for the first time to make a small little test project where it tells me the temperature and humidity using the DHT-11 Temperature and humidity sensor. I Verified the code, It says Compiling Sketch and it works, When i Upload it, it gives me these error messages. What Do they mean?

I then changed the ports to try on the Software and now it says this.

Sketch uses 4404 bytes (14%) of program storage space. Maximum is 30720 bytes.
Global variables use 293 bytes (14%) of dynamic memory, leaving 1755 bytes for local variables. Maximum is 2048 bytes.

nothing is open, Just the Arduino IDE.

First check the port you have used for the connection - if that’s not right nothing will work. You can remove the USB cable, check in Ports and make sure it is not listed, insert the cable and check again that it’s there. If you don’t see it listed then there is a USB driver problem.

Then check that the Board is right - Arduino Nano.

Then check that the Processor is correct. Options are Atmega328P, ATmega 328P (Old Bootloader) and ATmega168. It’s unlikely to be a 168, but it could likely be a version that requires the old bootloader.

Thanks but like what do you mean by the processor, I am very new and this is my first ever project on an arduino board.

When you select Nano as the Board in the Tools menu, you will get an option to select the Processor, with the different processors that are available for that board listed. Select the processor that corresponds to your version of the Nano. Note that it is almost impossible to tell which version you have (the “G” on the chip looks just like a “C”) so just experiment with each of the '328 options to see if one of them works.

Try to upload the basic blink code to the nano board. Also check if the cable is alright. Also follow all the instructions given by Jeff105671.

Hey Marcus,

Sounds like an awesome first time project on the Arduino, I think Jeff is definitely putting you on a good path to getting this project on its way.

Another great resource here would be having a look at our Arduino Workshop for Beginners as it is a very good way to start on the Arduino.

Cheers,
