New on the arduino project.

Good morning.

I'm new in the arduino project and I'm french, 58 years old.

I've perhaps doing an error for my first download. I've just downloading the sketch void setup and loop without other codes. But if I want now downloading another sketch??? Can I deleted my first sketch and remplaced by another???

Friendly.

Yes.

Simply uploading a new sketch will clear the old one.
That is all there is to it.

Good morning.

Thank you for your answer. I'm quiet now!
