Proposal

Description:

  • A single LED cube will be built using an ATmega 16 to control it
  • The ATmega 16 will be programmed with C using AVR Studio and an AVRISP MKII to load the program onto the micro-controller
  • The instruction set to program the micro-controller will be learned from the PDFs available on Atmel's website and from other linked websites
  • A breadboard will be used to aid in learning the instruction set and to ease programming
    • An ATmega 168 will be used in addition to the ATmega 16 while the instruction set is being learned


Progress:

  • All of the necessary parts to learn the instruction set for the micro-controller and build the cube have been purchased (see list below) - ✓
  • The C Programming website tutorials have been completed and a program for each section has been made - ✓ (click the links below to view)
    • Two sections should be done during each class
    • Sections completed during the last class should be reviewed to ensure that its not forgotten
  • Tutorials have been found that explain the programming process sufficiently (links to tutorials will be posted as they're found) - Ongoing
  • Start working with the micro-controller understand how it works - ✓
    • The breadboard should be used so circuits can be made, tested, and then disassembled
    • A blink LED program has been executed - Ongoing
      • Wire the circuit and load the program onto the micro-controller - ✓
      • Test the circuit and make sure the LED blinks - Needs Debugging
    • Other beginner programs should be made and tested - Ongoing
  • All of the necessary parts to build the cube have been purchased (see list below) - ✓
  • All parts have been soldered onto the proto-board and the circuitry has been wired - Ongoing
    • The LEDs have been bent, soldered into layers, and and soldered together into their final cubic form (see Pictures 1 to 6) - ✓
    • The remaining parts have been soldered to the proto-board - ✓
    • The finished LED cube has been soldered to the proto-board -
    • The circuitry has been wired and the micro-controller is ready to be programmed -
  • The programming of the main program has been started -
  • The final cube has been tested -
