Hello,
I am very new to Arduino ,as in I have just had it since Christmas. I was following a tutorial and now I'm done, the script is obviously still on the Arduino, have looked through the computer application for a clear or erase but I cannot find it. I want to make a completely different project but I cant find out how to remove my other scripts. I now there is a way to do it but I just cant find out how, any help would be appreciated.
Just upload a new one. It will overwrite whatever's on the Arduino. In fact, you should make it a habit, when you're done with one project, to re-upload the Blink sketch. This prevents you building another circuit, power up the Arduino and have things go wrong (short circuits and what not.)
If you are using windows, the arduino apparently makes a sub folder in the My Documents folder called Arduino, where the sketches are kept. You can make your own folders in the arduino folder for things like servo, serial, internet, etc. where you can keep your different types of sketches. You can also delete the sketch folders made by the IDE for the sketches you no longer want to cut down on clutter.
