KaramelTraktatie

Small low cost desk clock with Arduino to display time and temperature.

Introduction

This digital clock project is developed using TinyRTC module with added one wire temperature sensor. It is kind of complex however by using ready made modules bought in Ebay and also software libraries from other people, things get easier.

Note: This hobby project was developed a while ago in 2015 when the summer was very hot, while biking home I really wanted to know what the temperature in my room is. The code has been quite stable since then so not much updates.

Libraries needed:

LedControl by Wayoda:

• http://playground.arduino.cc/Main/LedControl
• https://github.com/wayoda/LedControl

OneWire

OneWire, maintained by Paul Stoffregen (website)

• http://playground.arduino.cc/Learning/OneWire

DS1307 (Obsolete)

Updated by bricofoy from Arduino Forums

• http://forum.arduino.cc/index.php/topic,93077.0.html

How to setup the time (via Serial Port)

Easy way

Use the time_updater.py script (don't forget to install pyserial first in your laptop).

Manual way

You can send manually serial bytes like what is shown in the code. Make sure it is 19 bytes.

// SET_YYMMDDdd_hhmmss
// SET_16030201_123001 (19 bytes)

karameltraktatie's Issues

Complete the README with a picture

A picture is equal to a thousand words. Set a picture to show how the system look like.

Update the DS1307 library

Somehow the library from brifocoy is gone. Change / update the DS1307 library.

Addition of Circuit Schematics

Add also the schematics. It helps in showing which pins are connected to which modules.
