Hello to everyone. Hi Thomas we met at Rome Maker faire 2019. I built the project but now I have a problem with arduino nano. lcd turns on but nothing else can be seen. I uploaded the '2019_06_01_Scanner' sketch and all the libraries. I couldn't load the precompiles (hex). I tried using xloader but the upload fails. I do not know what to do. I forgot to mention that with programming in general I am a novice.
