my project is as below....
i need to design a microcontroller(89c51) based temperature controller(thermostat)....My circuit must include a sensor(AD590),and analog to digital converter(ADC0809),a DAC0800,and a triac(BTA12) or relays to control the heater or cooler......though i have these components at hand,iam unable to design a circuit.I need help abt how to connect all these components together(i.e. how to connect the sensor to ADC,ADC to Microcontroller,Microcontroller to DAC and then DAC to triac)....i would be very grateful if u guys can kindly help..
