This Temperature PID regulator for Tamman ovens. Temperature is measured by thermocouple via lm358 - > Atmega s ADC and regulated over triac. All data is sent via RS232 connection on PC and controlled by LabView.-This is Temperature PID regulator

code for RS232 C# and ATmega

Interfacing HID USB class and Atmega microcontroller to windows instead of RS232 example.
