Arduino Blink ProjX




I'm both excited and feeling goofy this Christmas break. Excited to explore the world of electronics that I've desired for some time, and goofy at how proud I am of the super simple projects that I've prototyped with an arduino and breadboard. I had a Raspberry Pi in the past, but the way that I utilized that was mainly as a cheap CPU and for coding. Arduino seems to be much more aligned to making programmable electronics. Suits me fine!

Thus far I've used the Elegoo Uno R3 (super starter kit; Amazon $30), which is a clone of the Arduino Uno (I think). It came with a set of tutorials and thus far I am up to buzzers (lessons 5&6). All of the tutorials can be gotten free @ elegoo.com/download.

Here's a quick list of what I've made:

  • Blink_morse_i_love_u - The board "L" led blinks "i love u" in Morse code.
  • RGB_LED_USA - 2 codes:
    • switches LED from red to white to blue in a loop.
    • blends color from red to white to blue in a loop.
  • Digital_Input_LED - 1 button input pressed will trigger the morse "i love u" sequence and the other will turn the LED on for a few seconds.
Here are the codes written in Arduino IDE

I also found a few cool videos and updates for some things to think about moving forward as I seek to make cheap toys, gifts, nick knacks and other trinkets in the future.

Learning to be a TN Amateur Naturalist

#1 Google hit for "TN amateur naturalist" http://tnnaturalist.org/ Memphis Chapter, has good contacts from the biggest Naturalist institutions in Memphis. http://tnnaturalist.org/4-Memphis.html Promo of program from TN State Parks https://tnstateparks.com/get-involved/tennessee-naturalist-program The books I got from Memphis Library (Ben Hooks), the 500 section (574) on the 3rd floor. It will be good to reach out to some of the Memphis Chapter folks and see what I get back. Have to think through what "reaching out" means.

Plastic Origami Field Use Microtome

Plastic origami (plastic folder source) worked well to make specimen holder. 2 widths possible by either folding down on bottom to furthest stop or by placing bottom together in slit cut. Slide holder is filled with water and specimen is hand advanced with the slightest of nudges over the length of the specimen holder. Cuts are made on the other side of the glass slide, which holds the specimen holder in place and also acts to create a smooth cutting surface for better quality cut (using standard razor blade). The glass slide has a semi-ovular cut from the bottom using a steel wheel glass cutter (see video). This cut allows the specimen to advance beyond the glass so that the specimen can be cut. Cross sectional cuts of stem are picked up with needle nose forceps and placed on a slide. Extra water was absorbed with Kim wipes separating slides. Clear tape is used as cover slip to secure specimen to slide and then specimen are examined using Carson handheld microscope. ...
