I´ve build up one of the actuel projects, the sandclock, based on an Arduino Uno. I´m not e professional in programming. The initializing in Step 6 of the manual is free of errors. But the calibration after Step 31-32 fails. If I open the Arduino´s IDE´s Serial Monitor, an error occurs:
Invalid settings in EEPROM
The board himself is accurate detected, also the virtual port COM14, The BAUD-Rate is default 9600.
Can everybody help me?
Thank You so much,
