What is Schottky Diode? Schottky diode is a device, which comes under the type of a metal – semiconductor junction diode. Barrier diode and low voltage diodes are the other names for Schottky diode. When compared to a PN junction diode, power drop is lower in Schottky diode. A scientist named Walter.H.Schottky first discovered Schottky diode. Generally, in a PN junction device, when positive type (p-type) and negative type (n-type) are joined together they form a PN junction. However, in a Schottky diode, materials like aluminum or platinum are used instead of P type semiconductors. 

Let's come back to some basic electronic topics..

UNO is based on ATmega328P microcontroller.  UNO has 14 digital input – output (I/O) pins which can be used as either input or output by connecting them with different external devices and components. Out of these 14 pins, 6 pins are capable of producing PWM signal. All the digital pins operate at 5V and can output a current of 20mA.

Arduino UNO is considered to be the best prototyping board for beginners in electronics and coding.

Some of the commonly known and frequently used Arduino boards are Arduino UNO, Arduino Mega, Arduino Nano, Arduino Micro and Arduino Lilypad.

Arduino boards are generally based on microcontrollers from Atmel Corporation like 8, 16 or 32 bit AVR architecture based microcontrollers. The important feature of the Arduino boards is the standard connectors. Using these connectors, we can connect the Arduino board to other devices like LEDs or add-on modules called Shields.

What is an Arduino? Arduino is an open-source prototyping platform in electronics based on easy-to-use hardware and software. Subtly speaking, Arduino is a microcontroller based prototyping board which can be used in developing digital devices that can read inputs like finger on a button, touch on a screen, light on a sensor etc. and turning it in to output like switching on an LED, rotating a motor, playing songs through a speaker etc.

After a small idea abt IoT, thought of giving a small introduction about Arduino.. Just a refreshing session for those who already know abt it..

TCS is hiring.. Register on the given link.. Apply for the drive.. Hope it helps for you guys.. All da very best

Some sensors used in car..

9) What is interrupt latency? Interrupt latency is the time required for an ISR responds to an interrupt. 10) How to reduce interrupt latency? Interrupt latency can be minimized by writing short ISR routine and by not delaying interrupts for more time.

7) What is ISR? An ISR(Interrupt Service Routine) is an interrupt handler, a callback subroutine which is called when a interrupt is encountered. 8) What is return type of ISR? ISR does not return anything. An ISR returns nothing because there is no caller in the code to read the returned values.

The steps are : 1. Select the sensors which you want control. 2. Select the hardware through which you want to implement. For example, Arduino or Raspberry Pi or a BeagleBoard. 3. Next is software. IoT software encompasses a wide range of software and programming languages from general-purpose languages like C++ and Java to embedded-specific choices like Google’s Go language or Parasail.

The reason for sharing applications is that one can start thinking about developing your own IoT system..
