The toaster I'm using now has no lights. The thing is ancient.
You think like maybe put magnet on the door handle, with reed swithc nearby, 2 wires back to the controller? That could be doable.
I was going thru the AD595 datasheet, Table I on page 3 for the AD595 Output mV, thinking about how to get a temperature reading, interpolatng the data opr something.
Put the data for the range of interest, 0C to 300C, in excel.
Made a column to reflect internal ADC reading for the mV readings - and notived that the ADC reading were just about 2X the actual mV.
Plotted that out, tweaked it a little at the end, and got these results.
So could my conversion that I want to display & use for control decisions with be as simple as this?
AD595output = analogRead (temperaturePin);
if (AD595output<160)
{temperature = AD595output>>1; // divide by 2
else
{temperature = (AD595output>>1)-5}; // divide by 2, subtract 5
with the areas of greatest interest being:
preheat/soak at 150C to 180C,
reflow from 210C to 225C,
not to exceed of 255C.
