Changing the Mode of Operation of Pins: pinMode(pin, mode)           Used in void setup() to configure a specified pin to behave either as an INPUT or an OUTPUT. pinMode(pin, OUTPUT);                   // sets ‘pin’ to output           Arduino digital pins default to inputs, so they don’t need to […]

Structure of Arduino Program           The basic structure of the Arduino programming language is fairly simple and runs in at least two parts. These two required parts, or functions, enclose blocks of statements. void setup() { statements: }   void loop() { statements; }           Where, setup() […]

          After learning about the main parts of the Arduino UNO board, we are ready to learn how to set up the Arduino IDE. Once we learn this, we will be ready to upload our program on the Arduino board. In this section, we will learn in easy steps, how to […]

Arduino Overview           Arduino is a prototype platform (open-source) based on easy-to-use hardware and software. It consists of a  circuit board,  which can be programed  (referred to as a microcontroller), and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and upload the computer code to […]

TSOP 1738 IR Receiver           TSOP17XX is a commonly used IR receiver for Infrared PCM remote control systems. It is used in TVs, DVD Players, Burglar Alarms, etc. This component is built with PIN Diode, Preamplifier and internal filter for PCM (Pulse Code Modulation) frequency, and its epoxy package is designed […]

          An LED or a Light Emitting Diode is a semiconductor device that emits light due to the Electroluminescence effect. An LED is basically a PN Junction Diode, which emits light when forward biased.           Light Emitting Diodes are almost everywhere. You can find LEDs in Cars, […]

          A Laser Diode is a semiconductor device similar to a light-emitting diode (LED). It uses a p-n junction to emit coherent light in which all the waves are at the same frequency and phase. This coherent light is produced by the laser diode using a process termed as “Light Amplification […]

What is Bluetooth?          Bluetooth is short-range communication technology. The Bluetooth name is taken from the 10th-century Danish king Herald Blatant. Who combined Denmark and Norway.           Usually, when two electronic devices communicate with each other, they use cables, infrared rays, WiFi, etc. These are some of the […]

          A Multimeter is an electronic instrument, every electronic technician and engineer widely used a piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. It can also be used to test continuity between two points in an electrical circuit. […]

In an electrical circuit, a switch is used to turn the electricity on and off just like a valve is used to turn the water on and off. There are times when you want some water but don’t need all the water that the pipe can deliver, so you control water flow by adjusting the […]
