Technology Alternative - Arduino Uno with Simple LCD Display

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

Arduino Uno with Simple LCD Display

• Hardware:
• Arduino Uno (15),
• SD Card Shield (15),
• Screwpoint Adapters (10),
• LCD with Keypad Shield (10)
• Microprocessor:
• Flash Memory - 32 KB (ATmega328) of which 0.5 KB used by bootloader
• SRAM - 2 KB (ATmega328)
• EEPROM - 1 KB (ATmega328)
• Clock Speed - 16 MHz
• 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).
• SRAM limits board to taking 125 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).

 

The breadboard provides a voltage divider that uses a variable resistor to deliver a variable voltage for simulating a test measurement.
