MOSFET LED strip switching - with 3.3V control, using 555 timer PUBLIC

WIP on using a 555 timer IC to drive an IRF540 MOSFET for 12V LED strip PWM without needing the microcontroller to supply fast PWM. INCOMPLETE.

MOSFET LED strip switching - with 3.3V control active/active totem pole driver PUBLIC

Driver for IRF540 MOSFET that permits fast PWM of 12V load (LED strip) via 3.3V PWM control signal. Hopefully.
