tool to use to draw an electronic circuit

LTSpice is kinda standard. A nice thing about that is you can convert their file to a text file and post it in here, as long as regular test works. Needs nothing, no unicode or any of that s*it, just simple text.

The only problem is there is a lack of a few devices and it isn't quite a piece of cake to make one. for example a potentiometer.

You CAN make the parts, but then for them to work there has to be a repository or something for them because it has to also be on the recipient's computer. Like a font in a webpage, your browser has to download it.

But it works well, and you can get away without pots and change it later, it will simulate and all that and you can tell if the smoke is liable to come out or if it is going to oscillate or whatever.

ORCAD is one "industry standard". There is a free version on their web site. Easy to learn. Hard to post here.

Pots are super easy to make in SPICE. You make two resistors in series, with values {R*x} and {R*(1-x)}, then set or step x.

There's also always ASCII art.

Thank you you all 4 of you, gentlemen - I shall Google a bit about

Sebastian.

Everyone can then see it with no effort.

ASCII art example below: view in courier font

You can also draw a diode like this -->|-- or this _|\_ |/

or a resistor like this /\/\/\/\ or a cap like this --)|-- etc. With ascii art you need to use a fixed font like courier; proportional fonts will mess up the drawing.
