Here is my RTC (real time Clock) getting date/time from Mobile.
it stores the date/hour in rtc and keeps it with a coin cell help.
I used the 16x2 LCD
- Arduino UNO Rev3
- RTC (dallas)
- Crystal Oscillator
- Potentiometer
- Coin cell
- LCD 16x2
- Bluetooth rf wireless serial module
- Android app inventor software
with my mobile i can change time/date in Arduino.
It was a small project but quite hard for me. Hope you like the video.
