I connected the following pins to the Mega 2560: Vcc, Gnd, Gnd, 5V, Rst, Digital Out 10,11,12,13,Gnd and Analog Inputs 4 and 5.
As I checked the voltages at the pins I got nearly 5V at the pins A4, A5 and Digital Out 10 (even when I disconnected this pin from the Arduino) at the Shield, even though the regulator puts out 3V.
"RTC_DS 1307 does not name a type"
And how can I set the RTC automatically by the computer?
if (! RTC.isrunning())
Serial.println("RTC is NOT running!");
// following line sets the RTC to the date & time this sketch was compiled
but the correct time was taken by the PC
