I want to implementing Temperature RAMP (continues temperature increase per second). using microcontroller in C language.

Pleas somebody help me....

 

If this is not a school exercise and you need to get a job done, then you should be aware that there are dozens of inexpensive temperature controllers (1/32 DIN, 1/16 DIN, 1/8 DIN and 1/4 DIN) which perform this function. routinely.
