LCD KEYPAD Shield

Quick Overview
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

Features :

• 16X2 Blue color back light LCD.
• A single Analog pin is multiplexed to read 5 input Keys.
• Optional PWM based Back light control.
• Stackable on UNO shield

UNO ATMEGA328 Development Board - Programmed with Arduino

Quick Overview

Atmega 328 is one of the most commonly used Micro controllers with open source platform amongst many hobbyist and industrial communities. The simplicity and the low power of Atmega 328 helps design many prototype boards which could be used in numerous applications.We introduced RDL UNO Atmega 328 development board having common UNO interface to the available shields. The board also has inbuilt Xbee footprint with memory card interface in a single compact board without the need of doing external connections and hence as a whole the final product becomes cost effective. The RDL UNO Atmega 328 also includes 6 analog inputs, 14 digital I/O pins (6 amongst these could be used as PWM outputs), a crystal oscillator with 16MHz frequency, a 5 pin female connector to connect FT232 plugin, a power jack, a reset button and an ICSP header. This board does not have an inbuilt USB to directly load the program from the computer. As we all know, once the program has been dumped into the board, the part of the USB connectors become useless. So to load the program we have given common interface through FT232 breakthrough board where we can connect to a computer and load the codes into the RDL UNO Atmega 328. Since the USB interface has been removed, we have provided Xbee foot print and Micro SD card slot which is commonly used by many electronics enthusiasts. Once the program has been dumped into the RDL UNO Atmega 328 we can remove the FT232 plugin and could be used independently for other purposes.This board is fully compatible with Arduino like open source software.

RDL- UNO ATMEGA328 Development Board - Programmed with Arduino

Features : 

• Atmega328p- controller
• Standard I/O interface for UNO shield.
• Xbee foot print for RF/WiFi communication.
• Inbuilt Micro SD memory card slot for Data logging application.
• Programmable with Arduino open source.
