# JAMduino (Arduino Clock without RTC)
### __JAMduino (Arduino Clock without RTC)__ is a simple Arduino clock project using Arduino Uno & LCD Keypad Shield, without RTC module (Real Time Clock). Watch the video below ([click here](https://www.youtube.com/watch?v=ROXa1smvINY)) to see its action, then follow the instructions below to build your own JAMduino!
#
[](https://www.youtube.com/watch?v=ROXa1smvINY)
#
### **1. What You Need** :gift:
To build this project, you need the following items:
- 1 Arduino Uno board
- 1 LCD Keypad Shield
- Arduino IDE ([download here](https://www.arduino.cc/en/Main/Software))
- LCD Keypad library (I've attached its __.rar__ on this repo)
#
### **2. Schematics** :wrench::hammer:
Just plug the LCD Keypad Shield on top of Arduino Uno board.
#
### **3. Sketch** :clipboard:
- First, extract _**LCD Keypad**_ library (LCDKeypad.rar) then copy it to _C:\\...\Documents\Arduino\libraries_.
- Open Arduino IDE then copy sketch below. Make sure you have chosen the right option for **_Board_** and **_Port_** under **_Tools_** menu, then upload to your Arduino board.
```c++

### **4. Have Fun!** :sunglasses:
- After uploading done, you have to set the time manually first.
- On LCD Keypad Shield, use:
- Use :arrow_left: **left / right** :arrow_right: **button** to choose time option: _**HARI** (days), **JAM** (hours), **MENIT** (min) & **DETIK** (sec)_.
- Use :arrow_up: **up / down** :arrow_down: **button** to set its time, then your clock is ready to go! Have fun!
