Mosfet N, our savior
This time, i need to design and make an output device that is compatible with my final project.
Because my project is a heater device, and i want to manage a greater current than the usual in my board to generate enough heat, i choose to make a module that can handle this differences.
In our stock of parts there is a Mosfet N that can manage 5 volts/12 volts and can manage up to 50v.
Mosfet datasheetFirst, i design the new board to interact with my first one.

The programming
After testing the board to see if it has any shortcut, the programming session starts.
I made 2 versions, one with delay and the other with a push button to start and stops the heater.
Because this time i didnĀ“t have a good heater to test, i used a motor instead.
The result
What i have learnt?
I learned how to make a mosfet work, how to manage differetn currents with the same board for different aplications
