Hey, I am having trouble in displaying time and date when i upload the sketch and open serial monitor to see it. My problem is when i give 'y' character in serial monitor the setTime() function is executed which is fine because i want to set time and other parameters through serial monitor but WHAT I WANT IS WHEN I DONT PRESS 'Y' I SHOULD GET EARLIER VALUES OF TIME AND DATE FROM RTC AS A NORMAL FUNCTIONING AS SOON AS I OPEN SERIAL MONITOR AFTER UPLOADING THE CODE AND IN BETWEEN IF I GIVE 'Y' KEY IT SHOULD ONLY EXECUTE setTime(). so what should i do?
avrdude: Yikes! Invalid device signature.Double check connections and try again, or use -F to overridethis check. I am still getting the same problem again and again even i tried every step mention above with 2/3 affected ATMega328P-Pu IC. Please tell me what to do now?
