I cannot give a detailed answer, but if you are thinking that ACFG fills a LUT and therefore you cannot combine any other term into the LUT, then I think you have to break the pattern of thinking that equates a 4-input AND term with a 4-input LUT.
To get you started : looking at ACFG, you may note that CF is shared with another term, and so is AG. So you ...

Typically, automated cow tipping can be done by a simple programmable calculator or smartphone app. It doesn't take the complexity of a robot to calculate the normal 15-20%. If the milk is particularly good, 25% is not unreasonable. Chocolate Milk or Egg Nog, if completely natural and direct from the cow, deserves 50%!
The practice of cow tipping, ...

You certainly can build one of these, and Wikipedia claims that the Goodyear MPP was such a thing. It isn't quite, but it has most of the real elements that you'd actually want.
Putting the code in CAM as well offers you a lot of inconvenience for no real benefit, so you'd store it in regular DRAM. For practical purposes, you would have a CAM peripheral, ...

Using a micro controller seems like a wast for just a simple application.
My natural inclination is to agree. But there are other points of view. Here's an example of an equally simple application using a relatively simple microcontroller of the same family as that in your Arduino.

I'm assuming you are using brushed DC motors
Please correct me if I'm wrong but it sounds like you need to reverse each DC motor independently to give you the basic functionality you need so here is a basic DC motor reverse switch: -
Shown is a DPDT (double pole double throw) switch. It has two independent switches that mechanically activate together; ...

Remember that on this site, most people asking questions are building circuits in small quantity. If you only need one of something, then it can make sense to spend $20 on parts so you get it done and working in a reasonable time. If you need to build tens of thousands, then you'll want to spend a lot more time redesigning to get the unit cost down. That ...

Yes they do, particularly if the margins are very tight. That is part of engineering is to find the right solution, which for certain markets may be only about cost. That circuit above has 3 transistors and 3 diodes and with the pierce and blank phenolic board, might be only a few cents fully stuffed in volume production, for example the resistors in total ...

Low low low cost is the aim.
A small volume maker with no expertise in anything other than manual soldering (if that) can make these. They can be even made at home by workers if desired.
Single side phenolic board. Cheap.
Not only manual assembly but component size and hole spacings not well matched and leads are hand bent and nobody cares.
A design ...

Looking at that board, it wasn't even assembled with an ancient piece of pick-and-place machine - it was assembled by hand. In this case, I guess, the manual assembly was done for extremely low labor cost.
However, some other new designs use through-hole parts as well, most prominently switch-mode power supplies, even expensive ones. The reason is that you ...

As PeterJ says, the usual solution is coaxial cable. Because the wire down the centre is shielded by the outer braid (which should be connected to ground), it's not "visible" as an antenna and doesn't affect its effective length.
The 50 ohm controlled impedance avoids distortion of the signal down the length of the coax.

Rather than speculating how a particular designer built something (the video specifically states that individual servo motors were used), here is a method that will work:
Each "pixel" is controlled by a separate stepper motor (for minimum power use) or servo motor (for simple angular control).
Stepper motor pro & con:
Each pixel can be moved through ...

In order to how much cap to use where, you need to know a fair bit about capacitors in general:
The different types (electrolytic, film, ceramic, tantalum, OS-CON, metalized film, etc.)
Their characteristics (impedance, ESR, ESL, polarity, temperature rise, dielectric, etc.)
Their failure modes (aging, over voltage, reverse voltage, thermal runaway, etc.)

Calculate the peak current flowing through L1. If you are switching at a very low frequency that peak current tends to become V1 / R1. If you are using a reasonable switching frequency, the peak current in the inductor is mainly determined by the inductor.
When the inductor is open circuited that current has to flow somewhere and this is where the diode ...

You need to find the pin mappings in the project and update them so that you are using the "new" pins in your new project. Quartus has a GUI for this sort of thing.
I'm surprised it builds without that, but it may have just selected a random set of pins for you.
You'll need to get the pinout for the new board and decide for yourself which pins youwant to ...

The Diodes are the Mosfet body diodes. They are internal, and part of how the mosfet works. The Mosfet themselves are used as simple level shifters on the I²C clock (SCL) and data lines (SDA) enable I²C communication with microcontrollers operating at the same voltage as VIN (2.5–5.5V)
i2c, an open drain protocol, requires pull-up resistors. The value of ...
