Hi, I try to use my MPU6050 with an Arduino code but when I upload it I have this error :

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xac

avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x30

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

I tried everything, I chose the right Arduino and COM ...
Tank u for your help

That happens to everyone. Make sure the "insert" USB sound happens, or look at the hardware manager. IDE >> TOOLS >> PORT and TOOLS >> BOARD

Test your cable. You only should use data-cable for sketch uploading, the power cables are not suitable.

I think it is good because It appears on in IDE :

I am using this one :

I just noticed something !
Is it normal that at the back of the Arduino UNO the pins TX and RX are soldered together ?

Definatly not.

Would you upload a picture here? I am just curious to see the solder bridge (or if the copper pads touch).

there is this little metal bridge between them :

should I unsolder them ?

If you can get a full refund from the seller, try that first. If this board made it through QC, there is no telling what else they missed. If it is out of warranty, and you know how to solder well, use some solder wick (braided copper) to get only enough solder off to "un-bridge" the two pins.

[edit] A closer look seems to show the pins are touching. Maybe you only need to clip the tips of the pins so they do not touch? [/edit]

I just unsoldered the two pins and it is working perfectly !
How crazy !
Anyway, thank you for your help :slight_smile:
