Speaking of which, looks like they have a new "Arduino Workshop for Beginners" online course which might be of interest: https://core-electronics.com.au/tuto...beginners.html

Awesome. The Using SPI and I2C sections look very interesting.
Can be pretty hard to find information about these for beginners.

It turns out, actually physically making stuff is far more time consuming (and difficult for me) than making lights flash.

First test fit of my Light mounting system, could do with some work.

Not mine.

Most of it was nabbed from

Hey, looking at switching a 10W LED (12v, ~900ma) Floodlight with a Wemos D1 Pro.

Can someone tell me if this MOSFET will work with it? Pretty sure the logic voltage of the D1 is 3.3v

http://www.altronics.com.au/p/z1123-...et-transistor/

The datasheet says that it is Logic Level, so i'm hoping that means what I think it means

I'm not really sure how to read the values in the datasheet.
I believe it is the Gate−to−Source Voltage I need to look at, but I don't know what i'm looking for to know if it will work or not.

If that's not suitable, is there anything else that either Altronics or Jaycar stock that would be? (I just want something local where I can pick it up. As I just need the one it's easier than buying online)

Thanks

See in this link how they use a mosfet to drive a mosfet

https://www.aliexpress.com/item/High...01.4.14.EHAJ1o

depending on the application and the device, the 3.3 volts from the micro may not switch the mosfet on hard.
so the trick is to use a transistor to drive a transistor as a step in between

i was hoping to keep it as simple as possible and not use a transistor to drive the MOSFET if I could help it.
