hello, would like to ask to the expert what is the problem my arduino uno r3 board all onboard led keeps light on, it is possible to recover and it keeps error during uploading even the default loop sequence was uploading?
Welcome to the forum
Please describe the problem in more detail
Which board type and Com port have you got selected in the IDE ?
What happens if you do File/New then upload the basically empty sketch ? Which LEDs flash/light and do you get any messages at the bottom of the screen ?
Have you ever been able to upload a sketch to the board ?
If you get upload errors, enable verbose output during upload and disable verbose output during compilation and copy the full message here using code tags as described in How to get the best out of this forum.
attached picture is the actual board.. trying to recover if possible..
board: arduino uno r3 i dont know if this is a clone one
port: selected to Com6 as it is the available com under the tool-->port
Error Message: avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x5a
i cant upload the default sketch due to error
It's a clone one (I have several like it).
Disconnect the jumper wires from your board, especially the one going to Tx (pin 1) and try another upload.
that is the last one i did during some search of resetting to its original state.. i did search so many fixes but the board didn't responded.. same error showing on IDE
What were the red wires connected to? Did the board fail as soon as you connected them?
Ok, follow the advice in post #3 next.
Also please answer the last question in reply #2.
Have you ever been able to upload a sketch to the board ?
--- yes i upload it once an empty sketch from IDE and the rest of my test to upload already failed to upload
Great. Now is there any relation between the time you connected the red wires, and when it failed to upload? When it failed, what sketch did you upload? And, what is connected to the red wires?
after some search on how to hard or soft reset(if possible) the arduino, one of advice i've read is to short pin1(tx) and gnd(redwire) and upload empty sketch from IDE but still same result failed to summarize upload with or without the jumper still failed showing same error and also notice that onboard led are FIX ON i mean they are not blinking
Okay, zero out of three questions answered. Good luck.
Shorting pin 1 to GND only makes vague sense if the advice was referring to pin 1 of the actual 28-pin DIL MEGA328P package - NOT pin 1 of the header. Your board doesn't have the DIL package device fitted.
You've still not followed the advice being given to you, so good luck.
fyi.. found out that the quad IC is possible damaged don't know any reason.. after replacing new one, it now OK.. thankyou..
Myself, I would be taking a long, hard look at your proprietary, secret device on the red wires.
