Three channel fan speed controller for PC

Schematic Diagrams      Comments Off on Three channel fan speed controller for PC

Three channel fan speed controller for PC Jos van Eijndhoven have designed a 3 channel fan motor controllerbased on PIC 16F676 microcontroller. Mcu reads temperature from sensors and outputs PWM modulated signal to each output so the speed of fan is controlled accordignly. Three on board potentiometers controls the start… Read more »
