MOSFET is an electronic device having excellent switching characteristics, and is widely used in electronic switch circuits required, such as switching power supplies and motor drives, as well as lighting dimming. Relays are very familiar Another module has switching characteristics, but because the working principle of the relay is generally achieved by mechanical contact on and off purposes, which inevitably results in a very short time under the switch, the relay the situation does not work, another Baba sounds when the contact switch in some cases is more annoying thing.
 
Use this module electronic building blocks with Ard uino 4 IRF540 MOSFET switches use the same, but changes to the way the original four. Use reference Ard uino 4-way switch IRF540 MOSFET modules:
 
We designed this four MOSFET switch can provide up to 4 sets of electronic switches, were used to control the different circuit blocks. Affected MOSFET works, the electronic building blocks can be used to control the DC circuit, such as a DC LED screen, etc., are not suitable for controlling the AC circuit. The limit switch can be used to control the MOSFET 100V / 33A DC circuit, but control is not less than the minimum DC voltage proposal 9V.
 
On the circuit connected at one end of the connection is slightly more controlled some trouble. 12V to control the LED lights, for example, first to the positive ( ) and negative (-) connected between the power supply;
 
Then take positive LED lights with the module connected to the positive ( ) and negative LED lights with the connection to the switch 1 (S1);
 
If there are other LED lights with the need to control, the same LED lights with only the positive cathode module is connected to the ( ) and negative LED light strip is in turn connected to the switch 2 (S2), switch 3 (S3), the switch 4 (S4) on;
 
Wire control terminal is much simpler, we only need a sensor cable, the corresponding control port and Ard uino sensor expansion board connected, you can control these by Ard uino 12V LED lights brought. Experiment, we picked up two LED lights.
 
Test code is as follows:
 
int s1Pin = 6;
int s2Pin = 7;
 
void setup () {
  pinMode (s1Pin, OUTPUT);

Need to know before buy: some board can clip chip directly, but some board cannot operate like this, because the chip will be affected by the peripheral circuit on the board, please know before patting, lest buy back can't use, but the chip welding is quite a universal seat son can be used directly, and wide body, narrow body are universal.
Many high - power programmers are basically normal use
 
When encountering the programmer with protected function, the clamp cannot be read out under normal voltage. At this time, a 3.3v voltage should be added. The method is as follows: the clamp clamps the chip, and the clamp corresponding to the 8th pin of the chip adds a 3.3v voltage. Generally, the power supply of 3.3v has two wires, so it is ok for VCC to connect the clamp and the other wire to be directly grounded
 
 
Conversion block can use some chips is 1.8v such as huabang w25q64, wang hong mx25u1635, mx25u6435 and so on in 3.3v programmer for conversion burn. These chips are typically used on the motherboards of apple computers.

he cjmcu Large Digit Driver is a chainable controller backpack that can be soldered directly to the back of our large 6.5" 7-segment displays. Large numerical displays are a great addition to any project where you want to be able to see information at a distance. Scorekeepers and lap timers would be a great application for large 7-segment LED displays.
The cjmcu Large Digit Driver can easily be attached to the back of the 7-segment display by soldering all 10 castellations pins at the bottom of the board as well as the two additional castellations at the top. Keep in mind that the Large Digit Driver requires both 12V for the LEDs and 5V for the on-board TPIC6C596 IC. Each driver is equipped with six input pins and six output pins, these make the driver capable of being chained together. The input/output pins are listed as GND (Ground), LAT (Latch), CLK (Clock), SER (Serial), 5V (Power for the driver IC), and 12V (Power for the 7-segment display). We actually used the SparkFun Large Digit Driver in our AVC Battle-Bot Arena to display times and scores!

Conectar a ESP32: INMP441 ESP32 SCK> GPIO14 SD> GPIO32 WS> GPIO15 L/R> GND GND> GND VDD> VDD3.3 ¿Cuál es la diferencia entre un micrófono omnidireccional y un micrófono unidireccional?: en primer lugar, comprendo que la diferencia de sonido es total. Una persona habla y se diverge en el aire. En cuanto a lo lejos que puede pasar, depende de muchos factores. 1 micrófono direccional, el radio de recogida general es muy pequeño, 30 cm es grande, un solo uso, lo pones en la boca, la calidad del sonido es muy buena, porque no se recoge de nuevo. La forma es generalmente trigo de cuello de ganso, una varilla, una varilla curva, a tu boca, directividad, escucha tu voz. Con un micrófono de un solo punto, la sensibilidad se limita a un rango determinado. La sensibilidad es demasiado alta, causando silbidos afilados, etc., incluye muchos otros dispositivos en cuanto a por qué no hacer un gran radio de recogida, hay una razón. Más tarde 2 micrófono omnidireccional, el radio de recogida general es muy grande, un metro dos metros tres metros cinco metros tienen, en comparación con diez centímetros, este nivel es muy diferente, elegir la voz de una persona no es solo, sino varias personas, cinco, seis, siete, ocho o incluso diez. Los micrófonos omnidireccionales son altamente sensibles, el radio de recogida del micrófono omnidireccional es demasiado grande, Y también recogerá más ruido ambiental, así que la calidad del sonido no es tan buena como el micrófono de un solo punto, a menos que hagas una buena reducción de ruido. Definitivamente hay una diferencia entre el uso colectivo y el servicio de una sola persona. Pero el trigo omnidireccional tiene un beneficio, el cableado es simple, no uno por uno. Adecuado para reuniones pequeñas, reuniones especiales, algunas conversaciones remotas, operaciones remotas. 3. El trigo de un solo punto generalmente admite amplificación local, los micrófonos omnidireccionales generalmente no son compatibles con la amplificación local. Se debe tener en cuenta que debido a la alta sensibilidad, el silbido de amplificación local es muy atemorizante, y la tecnología actual es difícil de manejar.
