Technology Alternative - Arduino Mega with LCD Touchscreen

This post is part of a thread titled "What Technology to Choose for a Physical Interface Project"

Arduino Mega with LCD Touchscreen

• Hardware:
• Arduino Mega 2560 (40),
• TFT LCD Shield (10),
• TFT LCD/Touchscreen Shield (15)
• Microprocessor:
• Flash Memory - 256KB of which 8 KB used by bootloader
• SRAM - 8 KB
• EEPROM - 4 KB
• Software:  Arduino sketches written in C++ and downloaded to the microprocessor from a workstation.
• Supports 10bit resolution for Analog to Digital Conversion (external adapter can be added for higher resolution).
• Capable of taking 250 fixed time slice samples per second (assuming no updates of the LCD during sampling).
• LEDs could be used for indicating status during a capture (blink each second).  Shown upper left in picture to the right.

The breadboard provides a voltage divider that uses a variable resistor to deliver a variable voltage for simulating a test measurement.  It is also supporting a tri-colour LED as a status monitor while a test is running.
