One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display)  for proyotype applications. This shield uses minimum number I/O’s that is 4 bits for LCD data and 2 control signal lines for the same. A single analog pin (Pin A0) is multiplexed to read 5 input key switches (Navigation keys). Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin A0 on the board. Hence saves the no of I/O pins.  The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.

One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display)  for proyotype applications. This shield uses minimum number I/O’s that is 2 bits(D0 and D1) for LCD data . 5 input key switches (Navigation keys), when it's activated serial data will be sent to pin  D0 by internal 2 line LCD controller. Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin of internal 2 line LCD controller on the board. Hence saves the no of I/O pins.  The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.

The RS232 driver on board allows easy connection with PC or other embedded hardware . The board have User buttons and status LEDs. The bridge rectifire allow this board to be powered with both AC and DC power supply adapters.

The RASPBERRY PI MODEL B+-512M is a credit card sized computer that plugs into your TV and a keyboard, its like a little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word processing and games. It also plays high definition video. The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700MHz processor, VideoCore IV GPU, and 512Mbytes of RAM. The design does not include a built in hard disk or solid state drive, instead relying on a microSD card for booting and long term storage. This board is intended to run Linux kernel based operating systems.

This is a low frequency (125Khz) RFID Reader With serial Output with range 0-10cms. The RFID Reader  is designed specifically for low-frequency (125 kHz) passive tags.Frequency refers to the size of the radio waves used to communicate between the RFID system components.
