The issue with COBOL code is that it’s hidden. It’s mostly internal systems so little code available for training. HTML, TypeScript, JavaScript, C, etc, are readily available, billions of code lines.
This happens a lot on the Norwegian Wikipedia. It has a super-deleter, deleting hundreds of articles a month, especially on Norwegian artists, musicians and companies. Many of them have Wikipedia entries in other languages, but for that person, the bar is high. This pattern really scares people off.
Connect the led strip data pin to an available Io pin on the pi, connect the strips and to pi gnd pin and to a 5V power supply gnd pin, and connect the strips + to the 5V power supply.
You actually don't need more than the ESP32 and the led matrix. The LEDs are connected in series and you send a bit stream of RGB. Each led had an internal shift register with one input pin and one output pin, connected to the next LEDs input pin.
So one microcontroller with one output pin available is all you need. Since there is no clock signal, timing needs to quite tight.
To find more information you can google WS2812 or Neopixel. Libraries to use the protocol exists for most microcontrollers.
An ESP32 module is a good choice because it costs $2-3, includes wifi and BT, antenna or UF-L plug, and is pre-certified.
In Norway most homes have one or more heat pumps. We are living in a cold climate and the pumps are being used like 9-10 months a year.
The most common brands are Japanese: Toshiba, Mitsubishi and Panasonic.
I will not agree that the user experience is bad at all. They are very good products. Stand alone they work well and with integration they work together with the power company to optimize the energy consumption vs energy price during the day.
Be careful to just think the existing products are bad because you want them to be. It’s an existing, competitive, multi billion market with very good products.
Blame YouTube because they made the system. And if you dispute the claim, the clamer gets to decide if the clame was false. The system is totally wrong.
On YouTube, if you make a 10 minutes long video, but include 10 seconds of copyrighted material, the copyright owner gets 100% of the revenue, the creator 0%. I think this is YouTube creators main objection to the plattform.
