Hi, I have a problem with my Arduino mini. When I plug the Arduino in, the LED is on but my pc doesn’t always recognizes the Arduino. If it does, it doesn’t display data in the serial monitor. I think it should do that, like it is described in this Video: https://www.youtube.com/watch?v=9QZkCQSHnko . The wiring is also like shown in the Video, but I am using a logic level shifter for tx and rx. The Wifi module also lights up at the beginning, so I should work. The USB port is ok too. My problem is that I can’t connect to the Arduino. I tried uploading a sketch, but the Arduino IDE shows this error:
Arduino: 1.6.12 (Windows 10), Board: "Arduino Mini, ATmega328" Sketch uses 928 bytes (3%) of program storage space. Maximum is 28,672 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes. avrdude: ser_open(): can't set com-state for "\\.\COM3" An error occurred while uploading the sketch
If I try opening the serial monitor and changing the Baut rate, it shows this:
Error while setting serial port parameters: 115,200 N 8 1
I found out that my Arduino uses a chip made by a company called WCH, and I downloaded the driver for it. I think the installation worked. I’ve also got a problem because I can’t find “Ports” in my device manager. I can only tell if the Arduino is connected or not by the “Port” thing in “tools” in the Arduino IDE. Ps: I am using Windows 10 and I am a noob.
