Week 7

Week 7 has been pretty tough for me as it is a phase test's week. I did not get the chance to have a discussion with Mdm. Naza as the time is quite limited but I do get to go to Jalan Pasar to buy Arduino kit. I bought Arduino UNO kit for RM105 at Nixie Electronics with some other componets.  


Specification of Arduino:

  •        Microcontroller: ATmega328
  •        Operating Voltage: 5V
  •        Input Voltage (recommended): 7-12V
  •        Input Voltage (limits): 6-20V
  •        Digital I/O Pins: 14 (of which 6 provide PWM output)
  •        Analog Input Pins: 6
  •        DC Current per I/O Pin: 40 mA
  •        DC Current for 3.3V Pin: 50 mA
  •        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
Runs on: Windows, Mac OS X, Linux
Languages: Wiring/Arduino, C/C++
Getting Started guides: Clear step-by-step instructions, from download to blinking LED.
Knowledge base:
• Many simple examples included with download
• Good reference guide to the commands
• Large knowledge base on Arduino site and elsewhere
Advantage:
• Can be run as I/O board, using Firmata firmware
• Very large knowledge base
• Simple language, but expandable using C/C++
• Multiple models, for shields, breadboards, wearable, extra I/O pins
• Many shield modules
• Large number of open source derivative boards
Disadvantage:
• C language constructs (semicolons, brackets, case sensitivity) are confusing
