PC temperature controller
So we have a PC temperature controller by using a dallas DS1620 digital LSI with 9bit precision and 3 wire interface. Some of you might expand the bus to more sensors by keeping DQ,CLK pins shared all together, and selecting each one with the RST pin. PWM technique i 've used. About 60Hz carrier (i know so little), and a 2x16line LCD module in front of one spare PC slot. Also a pilot bicolor led, blinking when temperature is within some boundaries. Also a buzzer added just to make our world more beautifull. Sorry about my Greek english. I will be better in the future i hope. Cheers.
