ARDUINO BOARDS

Description: This is a 16x2 LCD and Keypad shield for Arduino Uno, Diecimila, Duemilanove and Freeduino boards. to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down, left and reset. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.

This Arduino compatible motor Driver shield is a full-featured products that it can be used to drive 4 DC motors or two 4-wire stepper and two 5V 'hobby' servo. It drive the DC motor and stepper with the L293D, and it drive the servo with Arduino's pin9 and pin10.

Features:

• 2 x L293D Motor Control Chips
• Total of 4 H-Bridges for controlling 4 DC motors or 2 Stepper motors
• 2 x Server ports for controlling RC Hobby Servos
• The logic control voltage Vss: 4.5~5.5V
• Motor Supply Voltage: 4.5 ~ 12V
• Reduced control pins needed through 8-stage serial shift registers
• Drive part of the operating current Io: 1.2A (0.6A per bridge)
• External power connection via a screw-terminal block
• Screw-Terminal blocks for connection to motors

Multi - Function Shield has a wide range of features which makes it perfect for beginners who want to study. It can be useful for advanced users because it has built-in general purpose components:

• USB 2.0 Full Speed compatible
• 3.3/5V operation level compatible
• All GPIOx pins break-out
• USB Host 5V/500mA supply for USB protocol
