Description
MOSFET is an electronic device with good switching characteristics, which is widely used in circuits that require electronic switches, such as switching power supplies and motor drives, and lighting dimming. Relay is another module with switching characteristics that everyone is very familiar with, but because the working principle of relay is generally to achieve the purpose of opening and closing by mechanical contacts, this will inevitably lead to a very short switching time, the relay Unable to work, in addition, the banging sound made by the contact switch is also an annoying thing in some situations.

The 4-way MOSFET switch we designed can provide up to 4 sets of electronic switches, which are used to control different circuit modules. Affected by the working principle of MOSFET, the electronic building blocks can only be used to control DC circuits, such as DC LED screens, etc., and are not suitable for the control of AC circuits. In extreme cases, the MOSFET switch can be used to control a 100V/33A DC circuit, but the minimum DC voltage for control is recommended not to be less than 9V.

In the circuit connection, the connection of the controlled end is slightly more troublesome. Take the control of a 12V LED strip as an example, first connect the power supply between the positive pole ( ) and the negative pole (-);

Then connect the positive pole of the LED strip to the positive pole ( ) of the module, and connect the negative pole of the LED strip to switch 1 (S1);

If there are other LED strips that need to be controlled, you only need to connect the positive pole of the LED strip to the positive pole ( ) of the module, and the negative pole of the LED strip is connected to switch 2 (S2), switch 3 (S3), and switch in turn. 4 (S4) on;

The connection of the control terminal is much simpler. We only need to connect the corresponding control port to the Arduino sensor expansion board through the sensor cable, and then the 12V LED strips can be controlled by the Arduino. In the experiment, we connected two LED strips.

The test code is as follows:

int s1Pin = 6;
int s2Pin = 7;

void setup() {
pinMode(s1Pin, OUTPUT);
pinMode(s2Pin, OUTPUT);
}

void loop() {
int i;

digitalWrite(s1Pin, HIGH);
digitalWrite(s2Pin, HIGH);
delay(500);

digitalWrite(s1Pin, LOW);
digitalWrite(s2Pin, LOW);
delay(500);

for (i = 0; i <10; i ) {
digitalWrite(s1Pin, HIGH);
delay(500);
digitalWrite(s1Pin, LOW);

}

for (i = 0; i <100; i ) {
