I got the Arduno today... installed the drivers and in 5 minutes had a little program running on it... They said it was easy.... I never thunk it would really be easy.
This is gonna be a blast. I also ordered an LCD display so I can display bean temp... and who knows what else.
I'm very interested in what folks think the variables in the profile should be....
Hey Milo ... great to hear you got the Arduino. Since it was so easy to do that much in so little time then you should be able to complete this project in 2 or 3 working days.
Yeah ... the LCD sounds like a great visual aid to what is going on.
Wouldn't it be cool if the Arduino could sense when the first crack of the roast comes to an end? You could work on a super cool automated green coffee profile that automatically adjusts the temperature depending on the type of roast you want to achieve. Maybe even if it had the smarts to detect the beginning of the 1st crack for getting a light roast. If it could detect the end of the first crack you would get a slightly darker light roast. Likewise you could detect the beginning of the second crack which would mean you beans would be darker again or the end of the second crack which would put your beans to a fairly dark roast. It might be called the universal bean profile ... or in this case the MiloVersal profile. Just thinking out loud here.
The LCD would be great to provide the total roast time, the current temperature, the stage length. If you can turn off the heat and only leave the fan on perhaps a message saying "cooling" would come on.
There are just so many possibilities.
