Introduction: Arduino Realtime Clock Using Ds1302

This week I decided that I want to build a clock. I want a clock that

always have the right time so I need a component that can do this I did some research and I found the ds1302.

Step 1: Watch the Video

I made a video on YouTube where i show you how to do it! So go check that one out.

Step 2: Code

Here are the sketches used in this project http://bit.ly/codeclock

there are three sketches and two libraries make sure you installed these

you need to install the libraries "ds1302" and "lcdi²c"

Step 3: No I²c Lcd?

if you don't have a i²c lcd it's not a problem. open the folder ds1302 and then go to examples then open DS1302_LCD connect the normal lcd screen and this would work fine.

Step 4: TechMaker

Your project is great so i want to add it in mine project . Thanks
