when I connect my Arduino Uno to my laptop the "ON" LED lights up but the L LED doesn't light up and when I press the reset button it doesn't blink
please help i can't afford a new one
by the way, I've been working with it for about 2 months now and I have a project due 1/4/2024
Welcome to the forum
What happens when you upload the Blink example sketch ?

The "L" LED will blink only if the Arduino is loaded with a "blink" program. Try loading, compiling and uploading the blink example:
FILE >> EXAMPLES >> BUILT-IN EXAMPLES >> 01. BASICS >> BLINK
You are late.
If you press and release the reset button, you should see a few quick flashes on the L-LED. If you don't see those, the 328P is either damaged or has lost the bootloader. The latter can be fixed with a programmer or second Arduino used as a programmer.
If your Uno isn't a clone with CH340 you can try the Loop-Back Test Instructions to check if there is more damage to your board. If that test fails on a board with the atmega 16U2 (the chip closest to the USB port) you probably have damaged the board beyond repair.
If this is a school project and your board is beyond repair, you can maybe implement it in wokwi and hope that the teacher accepts that.
Although that often is true, you don't know for sure in my opinion. OP might very well have been working on the project for a month or more, was doing the finishing touches and blew up the board.
@UKHeliBob
the Arduino IDE 2.3.2 doesn't recognize the port
I tried using three different cables and nothing seemed to work
but today when I plugged it in the L LED and the TX LED were working
but my laptop still doesn't recognize the port
I tried pressing then realising the reset button but nothing happened
I appreciate your help. It's great to receive a response finally.
