Programmer not responding Error keeps on occuring. Its Ardiuno UNO Made In Italy. Board Model: UNO R3 ![Screen Shot 2024-09-21 at 13.36.18](https://europe1.discourse-cdn.com/arduino/original/4X/d/b/b/dbb54945c12ab55ab309a7c6107cc8e0b257a065.png) this is the picture of the port. And i chose the the UNO R4 in the category cause i cant find the UNO R3 ---

The R4 definitely won't work if you have an R3. Perhaps you might look for just "Arduino Uno" in the list of boards. ---

> [@enkheee](#): > > on the port or the hardware itself Why not tell us both? We do not charge you by the word. Well in fact we do, it is word count \* nothing. What Operating system are you using? IDE 1.8.19 or IDE 2.x (where x is any number). Also I am getting nothing under the big arrow, that purports to be a picture of your port. > [@enkheee](#): > > And i chose the the UNO R4 in the category cause i cant find the UNO R3 The UNO R4 is a totally different processor to the normal Arduino UNO, If you choose that and do not have an actual R4 then not a lot will compile. ---

I don't use a Mac. See [IDE opens but there is no FILE menu - #3 by ptillisch](https://forum.arduino.cc/t/ide-opens-but-there-is-no-file-menu/1290539/3) which will probably help. ---

> [@enkheee](#): > > and btw it is on Ardiuno UNO Based on the topic title, you seem to have an upload problem. You've currently selected _/dev/cu.usbmodem101_. Are there other entries in tools / port? If yes, try those. I not, the question is if _/dev/cu.usbmodem101_ is indeed the Uno. To find out 1. Close that menu. 2. Disconnect the Uno. 3. Open the menu. If _/dev/cu.usbmodem101_ is still there, it's not your Uno. [Next page](https://forum.arduino.cc/t/programmer-not-responding-error-pls-help-me/1303676.md?page=2)
