MOSFET is an electronic device having a good switching characteristics， is widely used in the electronic switch circuit needs， such as switching power supplies and motor drives， and a lighting dimming. Relays are all very familiar with another module has switching characteristics， but because of the working principle of the relay is generally achieved by mechanical contact on and off purposes， which will inevitably lead to a very short switching times under the circumstances， the relay situation does not work， the other sounds when Baba contact switch in some cases is more annoying thing.
The circuit is connected at one end of the wire is slightly controlled some trouble. To control a 12V LED lights， for example:
First， the positive (+) and negative (-) between the connected power;
Then connect the positive LED lights with the module connected to the positive (+)，
LED lights with the anode connected to the switch 1 (S1) on;
If there are other LED lights with the need to control，
Just the same cathode lights with LED module is connected to the positive (+)，
LED lights with the negative electrode in turn is connected to the switch 2 (S2)， switch 3 (S3)， the switch 4 (S4) on;
Connection control side is much simpler，
We only need a sensor cable，
The corresponding control port for Arduino sensor expansion board connected， you can control the 12V LED lights brought by for Arduino.
Experiment， we picked up two LED lights.
