programming a supervisor based on Arduino

Hello my friends... I'm preparing my final project study this project is a supervisor with an Arduino Mega board with lcd 16 * 2 of an extruder machine. the quantities a controlled are:

the temperature of six areas (6 thermocouples) level reducer oil

For the temperature will be measured with a J-type thermocouple (analog signial) rotaion for speed will be measured with the tachometer (signial analogiue) ..

Each error to display the error and its location for example (err_temp_Zone0) or (err_temp_Zone1) .....

I find a difficulty:

1- convert thermocouple types J signial to Arduino

2 to make a plan for project programming

I did not find a competant person for this operation ... which can help me please it's urgent !!!! (Inbox)

and thank you

Are you offering money?

sorry...looking for help not for buying

You will only get that kind of help here if you show due diligence. Have a try at putting together the code, post it here in code tags, and many people will be glad to help with any problems.

Please do not cross-post. Other thread removed.

AFAIK the Mega can use differential analog inputs and includes an amplifier that may be able to make the thermocouple output directly readable.
