ARDUINO UNO THE ARDUINO UNO IS AN OPEN-SOURCE MICROCONTROLLER BOARD BASED ON THE MICROCHIP ATMEGA328P MICROCONTROLLER AND DEVELOPED BY ARDUINO.CC THE BOARD IS EQUIPPED WITH SETS OF DIGITAL AND ANALOG INPUT/OUTPUT PINS THAT MAY BE INTERFACED TO VARIOUS EXPANSION BOARDS AND OTHER CIRCUITS THE BOARD HAS 14 DIGITAL I/O PINS , 6 ANALOG I/O PINS, AND IS PROGRAMMABLE WITH THE ARDUINO IDE , VIA A TYPE B USB CABLE T E C H N I C A L S P E C I F I C AT I O N S Operating Voltage: 5 Volts Input Voltage: 7 to 20 Volts Digital I/O Pins: 14 PWM Pins: 6 UART: 1 I2C: 1 SPI: 1 Analog Input Pins: 6 DC Current per I/O Pin: 20 mA DC Current for 3.3V Pin: 50 mA 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 SPECIFICATION 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 E M - 1 8 F E AT U R E S A N D S P E C I F I C AT I O N S Operating voltage of EM-18: +4.5V to +5.5V Current consumption:50mA Can operate on LOW power Operating temperature: 0ºC to +80ºC Operating frequency:125KHz 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 T E C H N I C A L S P E C I F I C AT I O N S Standard 130 Type DC motor Operating Voltage: 4.5V to 9V Recommended/Rated Voltage: 6V Current at No load: 70mA No-load Speed: 9000 rpm
