			The controller will have an input of 5 buttons and 3 displays (2 x 4 Digit 7 segment for Actual and Target Temp and 1 x 16x2 LCD to show Kp Ki Kd, time, selected profile etc.) The oven's current theromocouple (k-type) will be attached to a MAX31855 (Range of about -270 to +1800 C, resolution of .25C), which itself will be attached to the arduino. The final component is a 480D10-12 solid state relay.

			The code will use the Brett Beauregard PID library (there may be a better choice but I liked reading the explanation of PID on his [http://brettbeauregard.com/blog/category/pid/ website]) as well as the LCD library and the 4D7S code from an old project.

__TOC__

== Summary ==
The kiln only has manual operation right now, where the operator chooses the maximum temperature, time and rate. This works for some materials, but other require more advancec control, so we will make it digital. With a triac, the already present thermocouple (and an accompanying thermocouple amplifier)and an arduino/esp8266

== Important Features ==
* Can reproduce old Controller's functions
** Rate Control (assuming linear)
** Timer
** Maximum Temperature
* Allow user to enter multiple target temperatures and rates over a long period of time
* Possibly using PID, if that's a good idea

== Cool Features ==
* Allow for multiple stored "profiles" of temps, rates and times
* Make the controller, and profile creator, accessible online
* Record power consumption
* Design a nice faceplate to replace the controller's current one

== Old Controller ==
Very simple and analog, operates at 240 AC and toggles a LC1D2501 contactor at frequencies above 1/60 of a hertz. Below are the internals, a simple sketch of how it is wired might be added later.
