One blue LED was simply amazing. I have a few more LEDs in different colors. Let’s do something like a mini-garland! [more...]
Last time, when the LED so delightfully shone, we completely lost sight of the need to somehow regulate the current on the GPIO, since 8mA, which set by default, a bit different from the desired 4mA. [more...]
Last time we calculated the electrical circuit and checked it on the breadboard. I had such an LED that we need to provide 4mA on any GPIO. Now it’s up to the software. [more...]
As a person who does not know which end to hold the soldering iron, I’m very afraid of damaging Raspberry Pi. Therefore I want to get a clear idea of how these GPIOs are designed not to fry them. [more...]
The top row of keys on the bluetooth keyboard Arteck HB030 by default works as multimedia keys to get Escape, F1-F10 you need to press the Fn key and one of these keys. To me, as a fan of Vim, it’s not very convenient. [more...]
