PWM Fan Controller You can see the PWM Fan Controller project here. The heart of the PWM Fan Controller is a PIC 12F675 microcontroller. This microcontroller is reading the analog output of a LM35 temperature sensor using a ADC (analog to digital converter) . The resulting digital value is converted to a temperature and a […]

Description Here’s another daft yet interesting PIC12F675 idea I came up with. When I wanted to show someone how logic gates worked I could only find a NAND gate which wasn’t very handy for demonstrating AND’s OR’s, NOR’s and ExOR’s. I also wanted to have a play with the A/D converter on the 12F675 so
