OneWire lets you access 1-wire devices made by Maxim/Dallas, such as temperature sensors and ibutton secure memory. For temperature sensors, the DallasTemperature library can be used in conjunction with this library. Download : OneWire.zip (Version 2.2) Hardware Requirements OneWire requires a single 4.7K pullup resistor, connected between the pin and +5 volts. Then just connect each 1-wire device to the pin and ground.
David Tuesday, March 26, 2013 I built an arduino using your instructions. Everything went well, so thank you for your detailed article. One comment I have is that when programming the board, I have been able to avoid having to hit reset as you describe in the \"Make it Work\" section by connecting a capacitor between the reset pin of the ATMega328 and the DTR pin of the FT232RL USB to Serial board. I had to use an alligator clip attached to the leg of the 10k resistor to get access to the reset pin. I\'m not sure why it works, but I learned about this idea from sparkfun customers Kevind and digifun in the comments section of the FT232RL USB to Serial board web page at https://www.sparkfun.com/products/718. CoreyK Thursday, February 21, 2013 I'm not sure why it won't print.
If you're like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects. The problem was that I'm such an electronics newbie that I didn't know where to start. After reading through many web pages and forums, I was able to put together this Instructable. I wanted to have the information I learned all in one place, and easy to follow. Comments and suggestions are welcome and appreciated as I'm still trying to learn all this stuff.
