• Hardware:
  • Adafruit 388 - super bright 5mm IR LED (transmitter):
    Adafruit product ID: 388
    940 nm, 20-deg beam width
    100 mA continuous, 1000 mA pulse
  • The basic sender circuit is taken from the Instructables project (link on IR home page)

  ---------------------------------------------------------------

• Software:
  • Adafruit:
    • from tutorial listed in ref/links on IR Remote home page
    • This program (my sketch: Ada_IRsendNikon_00) is designed to trigger the shutter on a Nikon camera.
    • The IR pulse times are manually extracted from the Adafruit IR receiver program,
      then are hard-coded into this sketch.
      However as mentioned in the tutorial, the actual timing values that are put into the send sketch
      are adjusted/tweaked from what the receive program puts out,
      based on actual scope measurements.
    • Note this approach does not require decoding of the raw data,
      since it hard-codes the raw data directly into the send sketch.
    • This approach, while functional and clearly showing proof of concept,
      is way too cumbersome for what I want to do.
