Hey,
I need some help with a school project. I'm building a light dimmer circuit with the use of microcontrollers; specifically using the PIC 18M2 to control the dimming of the light bulb. With 18M2, I am using a pwm code which can vary the voltage depending on a readadc input voltage. The code works perfectly but I would like to use a 7V filament bulb (so I can vary the voltage from 1-7V) as the output however the maximum voltage rating of the 18M2 is 4.5V. I was thinking about using a MOSFET to amplify this voltage but I'm not sure on how to do it. Does anyone know of anyway that this could be completed?
Thanks
