    Convert Float to Int

    My circuit consists of atmega8A , 16x2LCD ,increase button and decrease button my code is an example about convert float value to integer value (I need this function to write float value on serial EEPROM) the problem is that when use (int) structure, the result always less by 0.1 that problem...

    program or Algorithm for control of Muffle temperature

    My project is control of Muffle temperature by stable temperature rate rise . I use Atmega64 , thermocouple temperature sensor, 1800 watt heating coil (8A at 220 V AC). The driver circuit can change the current of heating coil by Accuracy 0.08 A (in the program code the set value changes from 0...

    Thermocouple amplifier problem

    I changed R23,C18,C20,R25,C26 and the result became a little bit better. While thermocouple input shorted to GND and after installing the AVR ,the ADC0 voltage became 45mv. I tried many times ,but I can't remove this 45 mv ,finally I readjust the offset potentiometer(R1) to make ADC0 equal...
