The JClock

Hello, my name is James Hubbard and I created this clock that I call the jClock. It uses a ds1302 real time clock module that can keep time more precisely than the Arduino can. This is what you will need to build it:
1. Arduino Uno.
2. ds 1302 rtc (real time clock)
3. Temperature sensor model TMP36
4. Breadboard
5. LCD screen 16 by 2
6. Potentiometer (for the contrast of the screen)
7. 220 ohm resistor”
