Did I draw my circuit diagram correctly for 2 MOSFETS and a solenoid?
My project consists of one 5 V solenoid (but uses 3.3 V), one voltage regulator (5 V to 3.3 V), one diode, two N-channel MOSFET transistors, and one 5 V LED strip, all controlled by a Raspberry Pi ...

Does a flyback diode have to be connected to the + lead of a solenoid, or can it go directly to the power supply?
I am designing a control box to switch 24V DC high speed solenoids at a max frequency of 200Hz. They will be controlled by an Arduino Mega through N channel, rfp30n06le MOSFETs.
Here is a photo of the ...
