I am facing a problem with my arduino uno. Unable to update any program. Board Led is not blinking it is in steady mode. It is not showing any error. If possible help me to solve out.

New subscriber sir always watching your videos ❤ many learnings

thank u brother it worked after ur tips

very hard to say where the problem is without properly debugging - have you checked if your SIM card has a SMS plan?

I have the same problem , can you pls tell where can I buy it and how to replace

I have an arduino uno which i ordered just recently, and code was getting uploaded to it perfectly fine, but when i powered it, it did nothing; I tried both the USB port as well as the DC jack which is on the UNO, but no response. What could be the issue?

Most likely the code may not be proper. Just make sure the the board its self is ok, compile and upload the blink example and check.

I cant able to upload code in my arduino i changed voltagw regulator and ATmega but still not able to upload the code the on light and L light is on. also the 5 volt arduino post shows 4.9 volt and the voltage regulator show 1150 insted of 1820 and.

Sir, I have purchased a new arduino uno r3 dip and tried to connect my laptop but laptop not recognised it. When I plug USB cable to laptop no plug in sound. Arduino power led on and pin 13 led blink 1 sec intervals. Is my Arduino damage?

Install the proper driver for the USB to UART converter.

An Arduino clone doesn't work for me either. I did it this way (but I still have to test it): desolder the little button and two pieces of wire connect the pins (where the button was soldered) and bridge with RESET and gnd !!! It will work. Let me know. :)

i have an Arduino uno R3(not clone ch340 driver didnt work) board which turns on the led is blinking from the start tried all the things turns out i do think it might be bootloader issue but not sure also it is not being detected in the com port section of the device manager Again the arduino turns on the led is blinking but no detection in the pc. Please help!!!

If it is not showing in device manager either the proper driver is not installed or the USB to UART converter chip is not working.

@@Circuitdigest Thank you, So i also installed the ch430 driver it showed it is installed and it is preinstalled for just checking if that works and it didnt, also any way we can fix the usb to uart converter chip? I will still try to check if any of the drivers work by reinstalling.

I am having a problem. When i connect the board TX, RX, L and ON all of these lights are on and IDE says not connected. I pre installed CH340 driver still no ports are showing. Please give me a solution.

my arduino "ON" LED blinks only once when i am plugging in. can i fix it?

@Circuitdigest

Ай бұрын

The ON LED is connected to the 5V line though a resistor. Check 5V line make sure there are no shorts and the 5V is present.

My arduino works when the USB cable is connected to the laptop but when I remove the USB to connect another power supply my program does not work. Please suggest what should i do?

If a pin is always in the same state regardless of the code, then post probably the pins is damaged.

Sounds like a hardware problem, My guess is that you have connected some motor or sensor which is consuming a lot of current forcing the Arduino to shut down and power on again. Remove all your hardware connections and try again
