Sandclock

[hinz.a]

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:

Reading EEPROM...
Invalid settings in EEPROM
Enter commands

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,
Andreas

I have found the reason for the error. The problem was sitting in front of the keyboard.

I build sandclock and it is running nicely. But all text is tilted to the left for about 10 degrees.
How to correct?

Thanks!

Same here.

In fact, I've found several problems:

Hello,

I can't access the PCF... Everything else is ok. I can vibrate the sand and calibrate the servos in the right way. But can set the clock but when I want to save the time, I get an error: Can't Access PCF....

Can anybody help me please? The battery is in and tested (2.9 V).

Thank you,
Pierre
