Introduction: RTC Ds1307 Arduino Based Alarm System
The hardware is the standard setup and is as follows.
DS1307 IC x1.
32MHz crystal x1.
3v battery for backup supply x1.
0.1uf capacitor x1.
Arduino Uno x1.
Step 1: Making an Arduino Prototype Board
Step 2: Making DS1307 Circuit
Step 3: Assembling Arduino, LCD and DS1307 :)
Step 4: Code
First compile and upload the code inside rtc_code 1.txt file. After uploading, compile and burn the second code inside LCD rtc_code.txt file.
Note the LCD pin configuration in the code. I have changed the default settings. You can change it by yourself
Step 5: Final Working Hardware
We have a be nice policy.
Please be positive and constructive.
