Those with a scientific background, sous-vide loving chefs or perhaps those making your own PCB reflow ovens will appreciate the following project by Chemical and Biological Engineering student Britt Liv Ulrike Michelsen. Britt has designed, built and documented an excellent programmable temperature controller than can operate with the Arduino PID library to accurately control the temperature and required rise and fall temperatures over time for a hot plate (or other device).
The results are quite professional, and Britt has supplied all the requried code, schematics and the design files to make the nifty control box shown in the image above. So for more information and to make your own, visit the project Instructable page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're wanting to make your own programmable hot plate or other off-board projects, you'll need an ATmega328P MCU with Arduino Uno bootloader:
This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our Eleven, EtherTen, USBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board.
It comes with the Arduino Uno bootloader pre-installed and has a special label stuck on top with details of the pinouts, so you don't even need to look up the datasheet when connecting it up in your project! For more information and to order, click here!
