🏃‍♂️ Running the Arduino CH340

🤔 Why I am making a gist about this particular model? because I've entered the world of arduino recently and I already got a lot of problems with this model. As I noticed with the few lectures I made, the arduino uno ch340 is a fake one (chinese copy) which has a few issues with being detected by the computer, so after saying this I'm going to make a short guide on how I managed to make it work (at least in linux, sorry windows users).

☑️ Validate that our model is the correct one

  • First of all make sure your model is the CH340G which looks something like this -> model
  • Once we confirmed our model is the correct we are going to continue!

⬇️ Download the IDEs

  • We are heading to the arduino documentation to download both of the IDEs (I'll explain now why we need both)
  • First we get the older one which is the 1.8.x you can get it -> HERE

Now we need to extract the .tar.xz file we got. We can do it with the next command ->

tar -xf <arduino-file>

That will create a folder, we cd into it

🏃‍ Running the scripts

  • Now inside the folder we may have the following files -> FILES
  • Next we are going to execute the file called arduino-linux-setup.sh with your username here is an example ->
chmod +x ./arduino-linux-setup.sh
./arduino-linux-setup.sh <username>
  • It may ask us to do it with sudo permissions, if so run it again with administrator privs
  • Is going to ask us for our password
sudo !!
  • After this our used is added to the dialout group and has the neccesary privileges

💾 Installing the latest IDE

  • Now is time to download the latest IDE from https://www.arduino.cc/en/software
  • Is going to be an AppImage so we need to give permissions to it.
chmod +x ./<file>
# Then we run it
./<AppImage>

You can also create an alias in your .bashrc (or anything you are using, in my case zshrc) something like this ->

cd
vim .zshrc
# Add this line
alias arduino="Path to AppImage"
# Then we source it
source .zshrc
# And run it with our newest alias
arduino

After all of this we aren't sure yet is our arduino board is going to be working or not in the IDE, so is time to test it!

😊 Run your first program

  • The first time you open the IDE is going to look like this ->

FIRST

Now we want to click where it says Select Board and there we are going to find the following things

  • Arduino Uno
  • USB Serial Port

It should look something like this ->

SECOND

Then we click OK to save it

  • Next thing is going to be that we wrote our code! I'll leave it a simple example of Hello World in another file in this gist, so copy it from there and paste it there.

Then we have something like this ->

THIRD

We click the two icons which are to compile and upload and we should get something like this ->

FIVE

And for the last thing we have to click in the Serial Monitor icon which is in the top right corner (The right one of the two)

FOUR

Then we got something like this in our console! ->

FINAL

And there it is! Our hello world is there, enjoy our chinese arduino!

hello_world.ino
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial.println("Hello World!");
}
void loop() {
// put your main code here, to run repeatedly:
}

You saved my day, thank you very much. All other webpages I found on the subject were only garbage.

The links to your images of your tutorial are broken (i don't care since i'm not using the IDE at all).

Also the script arduino-linux-setup.sh has a bug on line 226, trying to verify your user name although you do a sudo. I simply commented it.

Finally the output from journalctl -f when connecting my 2$ chinese Uno 👍

Hey! I'm really glad that your Arduino is working :)

Using discord as a CDN was not a good idea lmao, I need to find these images again and update it hehe
