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.
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. :)
@@thelegendarygamers1272 i remember having a problem like that - the reason was a fast loop in my code, try pressing the reset button on Arduino and releasing it just before your code starts uploading
@@Circuitdigest I have tried that but it did not have any effect on it. I installed the legacy Arduino IDE and there it showed me this error avrdude: verification error, first mismatch at byte 0x0000 0x62 != 0x0c avrdude: verification error; content mismatch On the newer IDE, I am not getting any sort of error. The sketch uploads without any sort of error on the newer IDE but it doesn't have any effect on the Arduino and it keeps running the same old sketch.
bro plz help me i facing a problem my ardiuno board has 3 red inbuilt led light on after it got sparked i am pressing reset button but it is not blinking
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?
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?
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?
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!!!
@@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.
Bro, I am connected gsm900a modul on this ch340g uno board, my for sending sms, my cunnection is good and cood are uploded the uno, after runing not recived any sms on my mobile phone, but serial monetor show sms sending
like i put a blinking code, it runs. I press the reset button and after the blinking it starts running again. I'm buying a new one so no worries I guess.@@Circuitdigest
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.
@@tawsifchowdhuryaraf8866 it could be that you tried to draw more current from the UNO board and thus damaged the voltage regulator. Use a multimeter to check your 5V and 3.3V pins on uno are giving the right output voltages
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.
Bro please help me com port not showing when I attach my UNO board with laptop. I've done everything I possibly can. CH340 driver is pre installed. I replaced my USB A-B cable. Still no ports or other devices showing in device manager. I've reset the Arduino board and my laptop as well. Nothing works. Please help!!!🙏🏻
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
I have a Arduino pro micro and successfully build a volume control with 3 touch button(ttp223), but there is a problem pro micro often got disconnect not fully (like light glow when i touch the sensor but no light on rgb ring and volume knob also don't work)automatically i don't know why and every time i need to replug it to pc and make it work, do you how to fix it link from where i made it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bMOuWbCsgPI.html
I was working with the Arduino and I accidentally followed the wrong circuit then smoke came out of the voltage regulator. I don't have a soldering iron
