Auto-corrupt strikes it's ugly head yet again. Should read "overseeded".

Hi! My name is (Elijah) and I am a recruiter with (Amazon). We are prepared to offer you a position as IT Director....
Nope. Nothing fishy there.

Adafruit has made some YouTube videos regarding such. Look for the Adafruit Industries channel, then Tariff Talk.

And, the JST-XH sockets are a bit big for where I wanted to use them. Bummer.

I ran into an issue. Things stopped working when I plugged in a second LED Driver board.
Problem turned out to be the pin where I was sourcing the power - BAT. The output of the battery charger is limited as to the amount of current it can provide. The 3V pin is a better choice.

One of my older frustrations is that I didn't have the words for what I was feeling. Everything required an explanation, and no one wanted the explanation.
I now have someone in my life who listens.

If I may chime in.
I stand 5'5", and I have a long torso with short arms and legs. Technically, I can "wear" a 3X, but it doesn't come down far enough to cover the bottom of my belly. I need a 3XLT - T for Tall.
I know. I'm 5'5", and need a Tall shirt. But, if I can't get a 3XLT, I won't buy it.

The idea is to transition the lawns into something low maintenance, and eco-friendly.
It should take about two years.

That means we have more space in the primary hull, with less space in the secondary hull/underslung Reliant-style torpedo pod.

I will need to review the sketch (programming) in detail, as he's a bit more advanced in C/C++ than I.
As expected, I went about things differently, using a small microcontroller and PWM LED Driver boards.
Also, we're doing a Jester class (Oberth class variant torpedo boat). Stay tuned!

I faded out my very favorite blue jeans that way. Then, I did the pen thing again.

Also thinking about how the various parts will connect. Looking at LEDs on pigtails plugging into JST-XH connectors on the LED Driver boards. Maybe the same for the LED Driver boards plugging into the microcontroller.
Still thinking about it. Will need to order MORE PARTS!

Taking a slight breather while I await incoming parts. Next on the agenda:
- Adding a second Adafruit TLC59711 PWM LED Driver.
- Adding the Adafruit STEMMA Speaker.
- Adding the QIACHIP RX480E Remote Control Receiver.
Meanwhile, looking at where the parts will go in the model.

Six channels of differing brightness, plus two channels showing the photon torpedo effect.

The ink is made up of different parts. The alcohol will help disperse the alcohol part, detergent like Dawn, may be necessary to break apart any oil part. That leaves the dyes and pigments. OxyClean is an oxygen bleach and may get dyes. Pigments? Not so much. They've gotten into the fibers.

I, then had to tweak the code to get the LEDs on the driver board to light the way I wanted.
It's getting close to the time to try to fit the bits together, and confirm my ideas.

Thought while sleeping about how I'd need a second LED Driver board for simplicity, and discovered how you'd address the PWMs on the second board.
This morning, I wrestled with the code, with the debugger correcting me with every change. Once the debugger was happy with syntax ...

I wrote a substantial portion of the sketch that I've been working on, in my head. I went over and over it, again and again, so that I'd remember it when I woke up.
Once waking, I started coding the sketch from scratch, putting down some ideas I had had previously.

Discovered last night that all the saves of modified sketches that I created were all overwritten by the same nearly blank file.
That's ok. I can write it better the second time around.
I was in a strange state last night. The body may have been sleeping, but the brain was awake.

I went through this last year with a Sharpie and a pair of my favorite jeans.
I'd start with rubbing alcohol to expand and dilute the stain, followed by a soak in OxyClean.
By soak, I'm suggesting a bucket of solution, and maybe a few days. Then, wash without soap.
Should lighten everything.

While waiting for parts, I need to figure out how to get the sound working, if not in #Arduino-IDE, then in #CircuitPython.

To connect to the STEMMA Speaker, we need three wires (GND, POWER/BAT, and A0/SIGNAL)
We don't want to solder wires into boards in the models, so we must use connectors. But, which connectors do we get?
- JST PH 2-pin cables for the speaker
- JST XH 5-pin cables for TLC59711.

The Adafruit Feather M0 Express microcontroller has a micro USB connector for power and programming, and a JST-PH2-pin socket for a LiPo 3.7V battery.
To connect to the TLC59711, we need to connect four wires (GND, Vcc/BAT, CI/SCK, and DI/MO).

I did what I intended to do. I came up with a "photon torpedo" launch glow-up and flash effect. Any other dynamic effect (warp, impulse) should be a variation of that effect.
I'm figuring out how to connect everything inside of a scale model, and adding sound.

Eh, with a market cap of 2.071T, they can lose a few bucks on a gamble.

Just knowing the easy answers isn't enough. At some point, I realized that the key is to be able to answer the easy questions quickly, in order to give you more time to answer the tougher questions.

I have played around with the code in my #Arduino sketches, and I have worked out most of the effects that I was looking for.
I've also realized that this is far easier to use trying to build something with discrete electronic component.

This morning, I “took a look under the hood” and looked at Adafruit_TLC59711.h. This let me see the special lingo used to operate the TLC board.
Afterwards, I did this:

I added calls to rainbow() and rainbowCycle() from loop(), and commented out increaseBrightness(). Much better.
You can get an idea of what the test sketch was hoping to showcase.

This morning, I took a look at the tlc59711test sketch. I was able to break it down into a number of functions: colorWipe(), increaseBrightness(), rainbow(), rainbowCycle(), and wheel().
Of these, only colorWipe() and increaseBrightness() were called from loop().
