About Here

This web blog is established for collecting useful information about building prototype with arduino or other applications. This page shuld help a designer with very basical technical cognition to build a working model or a prototyp for his design concept. We find prototyp or working model an excellent tool to test concept and understand it's usage in real condition (not only fantasy in mind). It's ofter very hard to realize every functions of a design concept. However it's our goal here to make this task easier.

What should be always keeped in mind is that we are not engineers and it's not our goal to design a perfect electron programme control. We are designers who are more willing to understand the users through prototype testing.

This web-site is still under construction and more information shall be collected. :)

How to memory arduino data when power drops

Use EEPROM on Arduino
Be Careful!! The number of time to write EEPROM on Arduino is limited. Arduino supports usually at least 100,000 times EEPROM writing.

or on a EEPROM chip, for example a 16 kBit EEPROM chip by conrad.de
