Arduino IDE question

I have weird symbols in my monitor appearing and I don't know how to fix it, can anyone help me?

Please post the code that prints those results.

Please read the forum guidelines to see how to properly post code and some information on making a good post.

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in a code block.

The number 1 cause for "junk" characters in the serial monitor - or any other terminal - like this:


is incorrect baud rate.

Images of code are nearly worthless. That is why we ask for the code to be posted as requested in the forum guidelines (linked in post #2).

ESP8266 outputs a startup message at 74880 bps, something like this:

Use the same speed in your sketch and the serial monitor and the garbage should be gone.
