Thanks for the reply and help!
I was looking at the code, where you have to store it in either the EEPROM or RAM of the DS1307, considering that I have multiple times that require an alarm, what would be the best way to approach this?
Looking at the code, please do guide me, since I'm still a newbie in programming. i out some comments on each line where I get confused.
void set_alarm(byte ah,byte am)
write_byte(1, ah); //ah is the hour?
write_byte(2, am); //am is the minute?
bAlarmHours=read_byte(1); //So this part reads the data from the EEPROM?
//Is this a new code? like as you said in your statement above, I can either use the EEPROM, or the DS1307 RAM.
byte read_byte(byte bAdress)
Wire.write(0x08+bAdress); // Set the register pointer to (0x08) to read first memory byte
Wire.requestFrom(DS1307_I2C_ADDRESS, 1); // In this case only read one byte
byte bRetVal = Wire.read();
void write_byte(byte bAdress,byte bValue)
Wire.write(0x08+bAdress); // Set the register pointer to (0xf3) to write the 11th memory byte
Wire.write(bValue); // Write the desired byte value
With regards to writing new values to the EEPROM without uploading new sketches, how is that done?
if I proceeded with the IF else statements, would it still be possible? Like if I add a "second" reading, and add it to the test, such as, "hour == 8 && minute == 30 && second == 01"? And just upload a new sketch every time i wanted to change the alarm times?
