hej Alle Danskere smiley-grin

Jeg har bare lige et par spørgsmål til Arduino! smiley-grin

1, Hvor/Hvordan lærte du hvordan man bygger med Arduino?

2, Hvor køber du dine ting? (Specielt selve Arduino pladen) og er det en dansk forhandler?

3, Modtager man Arduino pladen samlet eller skal man til at Lodde?

4, Findes der nogle Danske aktive arduino forums?

5, Tak for hjælpen!

Hej danskere smiley-grin

Jeg sidder og er kommet lidt i et problem. Jeg ved ikke hvad jeg skal lave smiley-grin. Derfor skriver jeg til jer om i kan give mig lidt inspiration. Det skal helst være et slags køretøj, men problemet er at jeg kun har nok til at kunne køre 1 motor..

Har i lavet noget sejt med 1 motor?

Tak for hjælpen!

The same thing happens on my Windows.. I dont thing i have installed the drivers for the Arduino, because when i connect it to the computer the "Found New Hardware Wizard" dosent pup up.

Do you know the tree LEDs are turned on?

Hmm... I have reinstalled the IDE and the driver, nothing happens... I do not think my mac sees that it is connected? I cant find it in the finder and it dosen't say any sound when i connect it..

When i write "Int" and pushes "Send", the text that i have written disappears. No other things happens.
