L293D Motor Driver IC L293D IC generally comes as a standard 16-pin DIP (dual-in-line package). This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins (if you do not use enable pins). Each chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. A motor driver is basically a current amplifier that takes a low-current signal from the microcontroller and gives out a proportionally higher current signal which can control and drive a motor. In most cases, a transistor can act as a switch and perform this task which drives the motor in a single direction. Turning a motor ON and OFF requires only one switch to control a single motor in a single direction. L293D IC generally comes as a standard 16-pin DIP (dual-in-line package).

Pinout: Pinout of  L293D Motor Driver IC Applications: High Current Motor Driver IC. Dual H-bridge for controlling up to two motors at a time. Ideal for Inductive load decoupling from the main/control unit. A wide voltage range allows for an adaptive voltage range control.

L293D Motor Driver IC (2 Pcs) L293D PowerDIP-16 Stepper Motor Controller/ Driver 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. The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. It is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic package which has 4 centre pins connected together and used for heatsinking The L293DD is assembled in a 20 lead surface mount which has 8 centre pins connected together and used for heatsinking. 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 rotate it in clockwise and anticlockwise directions, respectively. Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating. When an enable input is high, the associated driver gets enabled. As a result, the outputs become active and work in phase with their inputs. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. They are designed to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as their high-current/high-voltage loads in positive-supply applications. If you want to control the dc motor with these motor driver ICs, for that you will need few essential components like Arduino , breadboard , jumper wires , batteries or power supply . Note: Image may vary from actual product in terms of Manufacturer/Brand name according to the availability.

Dual H-bridge for controlling up to two motors at a time. Ideal for Inductive load decoupling from the main/control unit. Wide voltage range allows for an adaptive voltage range control.

L298N Motor Driver IC The L298 Motor Driver IC is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a high voltage, a high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage. The sense output voltage can be used to control the current amplitude by chopping the inputs or to provide over-current protection by switching low the enabled input. The brake function (Fast motor stop) requires that the Absolute Maximum Rating of 2 Amps must never be overcome. When the repetitive peak current needed from the load is higher than 2 Amps, a paralleled configuration can be chosen. An external bridge of diodes are required when inductive loads are driven and when the inputs of the IC are chopped; Schottky diodes would be preferred. POWER OUTPUT STAGE The L298 integrates two power output stages (A; B). The power output stage is a bridge configuration and its outputs can drive an inductive load in common or differential mode, depending on the state of the inputs. The current that flows through the load comes out from the bridge at the sensor output, an external resistor (RSA; RSB.) allows detection of the intensity of this current. INPUT STAGE Each bridge is driven by means of four gates the input of which are In1; In2; EnA and In3; In4; EnB. The In inputs set the bridge state when The En input is high; a low state of the En input inhibits the bridge. All the inputs are TTL compatible. Pinout: Pinout of L298N Motor Driver IC

Led Combo (R-G-Y-B-W) 5mm LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white LED and illuminates blue light. When a light-emitting diode is 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 colour of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor. It is good quality and durable & small size and super bright LEDs with Low heat dissipation, energy-saving, and a long lifespan. These LEDs are always in demand in the DIY community as well as in industrial applications.
