Electronic Building Blocks 4-way Switch MOSFET Switch IRF540 Isolated Power Module

If you have other LED lights with the need to control, just put the same LED lights with the positive electrode connected to the positive (+) of the module, the LED lamp with the cathode is in turn connected to the switch (S2) 2, 3 (S3) switch, switch (4) (S4) :

Control the attachment it is much easier, we just need to through the sensor cable, the extension of the corresponding control port and the sensor plate connected, can control these 12 v LED lamp belt.Experiments we pick up the two leds with:
