Ok, followed an online guide to a RFID kit, just the basic RFID board, LEDs, microcontrol, and a motor. Code provided wasn't quite working, messed with it a bit, click upload (after verifying, with not errors) and I get
avrdude: ser_open(): can't set com-state for "\.\COM10"
An error occurred while uploading the sketch
Serial monitor was set wrong, so I changed it to what the code had, which was 9600, but then I get this:
Error while setting serial port parameters: 9,600 N 8 1
So... I am actually kind of confused. I've incuded the code I'm using, incase that is required. In addition, I know this isn't the proper place to give feedback about my code, however I personnally am not against a little pointing-out-a-flaw Thank you, have a nice day!
