The Brainiacs

FEATURES   • Output Current up to 1A  • Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V  • Thermal Overload Protection  • Short Circuit Protection  • Output Transistor Safe Operating Area Protection    DESCRIPTION  The LM78XX/LM78XXA series of three-terminal positive regulators are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a Wide range of applications. Each type employs internal current limiting, thermal shutdown and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output Current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and current

 A push-button (also spelled pushbutton) or simply button is a simple switch mechanism for controlling some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, though even many un-biased buttons (due to their physical nature) require a spring to return to their un-pushed state. Different people use different terms for the "pushing" of the button, such as press, depress, mash, and punch. Uses:  In industrial and commercial applications push buttons can be linked together by a mechanical linkage so that the act of pushing one button causes the other button to be released. In this way, a stop button can "force" a start button to be released. This method of linkage is used in simple manual operations in which the machine or process have no electrica

 Features:  ➢ Wide supply-voltage range: 4.5V to 36V  ➢ Separate input- logic supply  ➢ Internal ESD protection  ➢ Thermal shutdown  ➢ High-Noise-Immunity input  ➢ Functional Replacements for SGS L293 and SGS L293D  ➢ Output current 1A per channel (600 mA for L293D)  ➢ Peak output current 2 A per channel (1.2 A for L293D)  ➢ Output clamp diodes for Inductive Transient Suppression(L293D) DESCRIPTION:  L293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors. L293D contains two inbuilt H-bridge driver circuits. In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15. Input logic 00 or 11 will stop the corresponding motor. Logic 01 and 10 will r

 A DC motor is an electric motor that runs on direct current (DC) electricity. In any electric motor, operation is based on simple electromagnetism. A current-carrying conductor generates a magnetic field; when this is then placed in an external magnetic field, it will experience a force proportional to the current in the conductor, and to the strength of the external magnetic field. As you are well aware of from playing with magnets as a kid, opposite (North and South) polarities attract, while like polarities (North and North, South and South) repel. The internal configuration of a DC motor is designed to harness the magnetic interaction between a current-carrying conductor and an external magnetic field to generate rotational motion Let's start by looking at a simple 2-pole DC electric motor (here red represents a magnet or winding with a "North" polarization, while green represents a magnet or winding with a "South" polarization).   Every DC motor h

 Outputs of one gate can be connected to inputs of another within the same chip or to another chip as long as they share the same ground. The figure to the left illustrates a basic circuit showing how to wire inputs and using LEDs to display outputs. The 7404 is an inverting buffer, especially useful when the output of one circuit cannot sink much current. A computer's parallel port is a notorious example and can easily be damaged by excessive current draw. Each of the parallel ports outputs can be connected to one of the six inputs on the 7404 hex inverter chip. However, more than one 7404 will be needed to interface all of the parallel port pins NOT GATE Logic-Rules:  The output is the inverse of the input, in other words if the input is HIGH then the out put is LOW and if the input is LOW the output is HIGH. Features:  Output Drive Capability - 10 LSTTL Loads  Outputs Directly Interface to CMOS, NMOS and TTL  21 Large Operating Voltage Range  Low Input Current  High Noi

  A light-emitting diode ( LED ) is a semiconductor light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting . When a light-emitting diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons .   This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. An LED is often small in area (less than 1 mm 2 ), and integrated optical components may be used to shape its radiation pattern. LEDs present many advantages over incandescent light sources including lower energy consumption , longer lifetime , improved robustness, smaller size, faster switching, and greater durability and reliability. Light-emitting diodes are used in applications as diverse as replacements for aviation lighting , automotive lighting as well as in traffic signals . The comp

  Diodes are used to convert AC into DC these are used as half wave rectifier or full wave rectifier. Three points must he kept in mind while using any type of diode. 1. Maximum forward current capacity 2. Maximum reverse voltage capacity 3. Maximum forward voltage capacity The number and voltage capacity of some of the important diodes available in the market are as follows: ·    Diodes of number IN4001, IN4002, IN4003, IN4004, IN4005, IN4006 and IN4007 have maximum reverse bias voltage capacity of 50V and maximum forward current capacity of 1 Amp. ·    Diode of same capacities can be used in place of one another. Besides this diode of more capacity can be used in place of diode of low capacity but diode of low capacity cannot be used in place of diode of high capacity. For example, in place of IN4002; IN4001 or IN4007 can be used but IN4001 or IN4002 cannot be used in place of IN4007.The diode BY125made by company BEL is equivalent of diode from IN4001 to IN4003.
