ESP8266- Rain drop Sensor Interfacing


Program


#define DO_PIN    D2  // The ESP8266 pin connected to DO pin of the rain sensor

void setup() {

    Serial.begin(9600);

    pinMode(DO_PIN, INPUT);

}

void loop() {

   delay(10);                      // wait 10 milliseconds

  int rain_state = digitalRead(DO_PIN);

  if (rain_state == HIGH)

    Serial.println("The rain is NOT detected");

  else

    Serial.println("The rain is detected");

  delay(1000);  // pause for 1 sec to avoid reading sensors frequently to prolong the sensor lifetime

}

System Bus Types, Functions, and Features

Image
                                    System Bus Types, Functions, and Features The heart of any motherboard is the various buses that carry signals between the components. A bus is a common pathway across which data can travel within a computer. This pathway is used for communication and can be established between two or more computer elements. The PC has a hierarchy of different buses. Most modern PCs have at least three buses; some have four or more. They are hierarchical because each slower bus is connected to the faster one above it. Each device in the system is connected to one of the buses, and some devices (primarily chipset) act as bridges between the various buses. The Processor Bus (Front-side Bus) The processor bus (also called the front-side bus or FSB) is the communication pathway between the CPU an...

Motherboard form factor

Image
The form factors refers to the physical dimensions (size and shape) as well as certain connector, screw hole, and other positions that dictate into which type of case the board will fit. The more commonly PC motherboard form factors include the following 1  PC and XT The first popular PC motherboard was the original IBM PC released in August 1981. Fig. shows how this board looked. IBM followed the PC with the XT (eXtended Technology) motherboard in March 1983, which had the same size and shape as the PC board but had eight slots instead of five. Both the IBM PC and XT motherboards were 9”×13” in size. The XT also eliminated the little used cassette port in the back. 2  Full size AT (Advanced Technology) This board was 12”×13.8” in size. To accommodate the 16 bit 286 processor and all the necessary support component at the time, IBM needed more room than the original PC/XT size boards could provide. So for the AT, IBM increased the size of the motherboard...
