Caution: This page is under development and is deeply clouded by the author's lack of significant experience with microcontroller programming.

Typical basic stuff to work through. The following assumes learning with a high-level language (e.g., C or JALv2); the order probably needs to be tweaked.

• Hello world :: blink LED
• Basic interaction, polling :: switch controlled LED
• State, switch bouncing debouncing :: toggle LED with switch
  • S/W debouncing algorithms
    • delay (inline and function or macro)
    • “confidence counting”
  • H/W debouncing
    • S/R flipflop
    • Schmitt trigger
• Multiple states :: switch toggled multiple LEDs
• PWM :: switch stepped LED intensity
• ADC :: {something else} stepped LED intensity
• Interrupts
  • External :: switch controlled LED rewrite (w/ and w/o state)
  • Timers :: blink LED rewrite
  • Multiple external :: Mmltiple switch-based {something}
• Watchdog timers
• Libraries
  • 7-segment displays
  • LCD displays
• Communication buses
  • Serial
  • SPI
  • I2C
• Switch matrices
