output port on computer. I have loaded and uninstalled my program several times, but for what ever reason my Arduino uno will not connect to my port. I have used other devices and they work ok . The computer will not recognize the port no matter what port I use. I have followed all instructions to fix the port but with no progress . I have had computer problems , however they have been rectified.
Any Ideas anyone?
