Control your devices through PWM with a Fusion Brain and this Output Board. This is an easy solution to speed control for simple DC motors. PWM can also be used to get an analogue output from the Fusion Brain through a simple RC filter.
 



 
How to use the MOSFET Power Output Board
 
Pins 1 and 2 are connected together, and need to be supplied with the same voltage as what you are switching. Pin #4 controls the MOSFET on the left when grounded, and pin #3 controls the MOSFET on the right when grounded.
 
The Fusion Brain works with switched grounds. So when you connect the FB to the MOSFET board, connect the + side to the "bottom" pin and the - side to the "top" pin. The drains of the MOSFET are on the outside bottom 4 pins, and the sources are the middle two. 
 
For best operation, the sources should be tied to ground, (it needs to be the same ground as the Fusion Brain). Then your load gets power normally, and the ground of your load is connected to the drain pin on the MOSFET. So when the Fusion Brain turns on an output, the pin is grounded, and the MOSFET allows current to flow through the power source, to the load, to the MOSFET, and to ground completing the circuit and turning on the load.
