Use MOSFET to Change Voltage With PWM
Ok so forgive me for being an amateur but I'm having a situation that's driving me nuts.
I have a sensor that I have to cycle between +5VDC and +1.4VDC every 60 seconds. I'm using an ATTiny85 with ...

Best way to make an Arduino switch 8 12V LED's
I'm trying to switch multiple 12V LED's with my arduino, based on the input of a (serial-in parallel-out) shift-register.
The 12V comes from a separate battery, so I can use 8 mosfets to get my 12V, ...

Why are MOSFETs only giving 8.1V for LEDs, not 12V?
I'm using three PWM outputs from an Arduino Mini Pro to drive the R/G/B parts of some strips of LEDs. The circuit is basically this:
I've got a single 12V power supply, rated at 200W, to light the ...

Using an Arduino to switching a grounded load powered by a 12 Volt supply
I wish to use a MOSFET to drive a 12V rated LED strip from an Arduino.
The negative side of the LED strip must be connected to ground, so that means that the driving MOSFET must be between +12V and ...

When should I use a transistor, mosfet, and when should I use a relay?
I am used to relays some, and they are useful, especially for large loads like a incandescent light bulb or other 120V AC device. However, it seems like overkill to use a relay for a bunch of LEDs ...
