Introduction: How to Use MOSFET As a Switch
In this instructable i am going to show how you can use mosfet as a switch
basically it has two uses
1 - as a switch
2 - as an amplifier
A COMPLETE EXPLANATION IS GIVING IN THE VIDEO AS WELL
Step 1: Selecting MOSFET
Here iam using power mosfet ir540
you can use any low power mosfet depend on the condition like 2n7000 etc
Step 2: Circuit Diagram
Impliment the above circuit on breadboard or etc
for login state you have give 5 volt signal at gate to turn on / off this can be done via voltage divider circuit with a help of a switch .....
give a pwm signal from arduino / microcntroller etc to switching the mosfet,
We have a be nice policy.
Please be positive and constructive.
