The L293D is quadruple high-current half-H drivers
L293D
MOTOR
DRIVER
It is designed to provide bidirectional drive currents of up to
600-mA at voltages from 4.5 V to 36 V. Both devices are
designed to drive inductive loads such as relays, solenoids,
dc and bipolar stepping motors, as well as other highcurrent/high-voltage loads in positive-supply applications
Drivers are enabled in pairs, with drivers 1 and 2 enabled by
1,2EN and drivers 3 and 4 enabled by 3,4EN
Wide Supply-Voltage Range: 4.5 V to 36 V
Separate Input-Logic Supply
Internal ESD Protection

Thermal Shutdown
High-Noise-Immunity Inputs
Output Current 600 mA Per Channel
Peak Output Current 1.2 A Per Channel
EM18 RFID
READER
• EM18 RFID Reader is a module
which reads the ID information
stored in RFID TAGS. This ID
information is unique for every
TAG which cannot be copied
EM-18 is used like any other
sensor module
HOW TO
USE EM-18
RFID
MODULE
Step1: Establishing a mode of
communication
Step2: The output of
MODULE bit rate is 9600bps

A DC motor is any of a class of rotary electrical
motors that converts direct current electrical
energy into mechanical energy
DC MOTOR
The most common types rely on the forces
produced by magnetic fields
Nearly all types of DC motors have some
internal mechanism, either electromechanical
or electronic, to periodically change the
direction of current in part of the motor
