Arduino programming by USB to TTL converter

How to program Arduino UNO or Nano using cheap USB to TTL converter.

Plz Comment your query

The schema where outlined that RX pin is connected to TX one and vice versa helped me a lot! Thank you very much.

[albinjose]

Thank you so much... I am looking for a solution for one day. Now this problem got solved... Thank you. Nice vedio. Keep it up.

Yesterday, I was able to restore an Arduino UNO clone and it started working again simply via the "Arduino ISP" skecth. It works. A second UNO clone on the other hand once turned on remains with four smd leds on and is bricked up but I must restore it at all costs. Then NANO boards that do not work with this process. I have a usb ttl P2023 and tomorrow I try admittedly not granted I can find 6 wires to connect and then via arduino isp I have to solve. let me know further solutions. Thank you very much.

Thank you i have been struggling to make my own arduino clone, and your tutorials helped me so much

This converter also has a DTR pin. Just solder to 2 pin of the IC

[sfcoawol]

wouldn't you just put a jumper from ground to reset pin? or is there a reason for holding the reset button?

I dont understand is it just for uploading code to atmega328p or we can also flash and installed bootloader for a new atmega328P chip as into a new chip we firsttime have to flash then only we can put the code into it

Is the arduino pro micro bootloader programmable with ch341a

amazing it worked for my arduino help me a lot

[santhoshsrinivasagan]

Thank you much!
u literally saved my project.

great video.. now time 4 me to program...:/ thanks...:)

What will happen if I have DTR pin but didn't connect to reset pin?

[yashchiman]

While using ttl to usb, we are not able to use the serial monitor, if any solution 🙏

[sto]

can you burn the boot loader using this method?

[naveenjangid]

I do step by step, but i not get the arduino programe file found in ardunio app.

[xuhuidong]

does it work for avr programming on arduino?

[abdullahyousef]

I have a problem I can not solve:


1. I downloaded the driver and windows is able to recognise my arduino
2. I have an arduino clone
3. The bootloader is working because when I press the reset button the L led blinks 3 times
4. I choose the correct board in the arduino ide which is arduino uno
5. I choose the correct com port
6. I have done the loop back test and it has failed for some reason.

And after all of this it still can not upload to my arduino for some reason I always get this error code:

With this TTL converter, can I fix the Arduino UNO clone driver problem? IC 340G but not from signs of life. With this ticket is it possible to restore Arduino? Instead with Arduino Nano I've never had problems !!! Thanks so much.

Thank you for this great video! I'm new and this is exactly what I needed to know.
