Description

For Source Code see: http://arduinofun.blogspot.com/ This is a video demonstrating a prototype programmer for Maxim's iButton temperature and humidity data loggers. The programmer can start / stop data logging missions and read the latest data point in the field without a laptop! The programmer uses a microcontroller called Sanguino, which is a more powerful clone of the popular Arduino microcontroller. See http://sanguino.cc/ for more info. The 16x2 LCD is from Newhaven running in I2C mode and was purchased from fungizmos.com. The button debounce IC is Maxim 6818. It can handle up to 8 buttons! See this video for a great tutorial on surface mount soldering: http://www.youtube.com/watch?v=3NN7UGWYmBY Real time clock is a DS1994 iButton. Supported sensors include: DS18S20, DS1921G, and DS1923 temperature and data loggers. Next step is to clean up the code and make a usable device for use in the field! Jeff
