I’m playing around with first examples in arduino ide and rephone.
The upload of a sketch works without any error, but the serial monitor shows only weird signs in endless order:
On line contains:
- starts with: ÿ
- then a sign from the ascii table
- then somthing I cannot paste here
This goes through the hole ascii table and start from begin again.
But my “Hallo world” does not appear
Any hints?
