Getting errors when trying to load code to Nano chip

[markdonofrio]

I am using the ELEGOO NANO (ATmega328P & CH340 chip - I installed the latest drivers on it)

I tried to add the 2.4 GHz Band Scanner & Jammer With NRF24L01 code to the nano via Arduino and I am getting multiple errors.

Hi as I respond to your email it seems like this is a problem with your Arduino library directory. I suggest that you reinstall your library and update your Arduino IDE.

Also the Display you currently using is not suitable for this project.

The required library for this project:

• Adafruit_SSD1306
• Adafruit_GFX

In this part of repository I explain how to install them from Arduino IDE.

thank you.

Will this display work?

[cifertech]

Yes, both will do the job.

[markdonofrio]

Can I hire you for 1 hour to share screens and help me complete this project? Would have to be after I get the proper display in 1-3 days.

[cifertech]

If you need help I will be here.

[markdonofrio]

One more question. Should I follow the instructions on the cover of my Nano chip box first before your steps? or leave the nano chip as is and skip box instructions?

[cifertech]

of course, if you don't have the ch340 driver installed, follow the instruction or simply search for it on google.

[markdonofrio]

I got the new LCD screen you recomended. Then when I tried to load the RF_Box Arduino file (after installing libraries), I get error below. Please help fix it.

I Installed version 1.8.12 of Arduino and it said download complete, but the device did not automatically start working as you said.

Hi @markdonofrio . the new display is fine and for code/schematic everything in the related repository is could be trusted to work with.
as I test these codes with no problem it might be a problem with your Arduino libraries which are installed before.
I recommend that clear your Arduino library folder and install the needed one again or simply use another computer.
because codes are fine and the issue is in your software. As far as I know.
