The idea for the pxlDigit_PCB came to me during the construction of the pxlDigit (article here: https://nerdiy.de/howto-elektronik-sieben-segment-ziffer-pxldigit-aus-ws2812-leds-bauen/). There the pxlDigit is built from single WS2812 LED segments. For this, the LEDs must first be inserted into the 3D [...].

The PCA9685 is a quite practical IC. It is connected to the microcontroller (for example ESP8266) via I2C and can then control up to 16 individual PWM channels. So you can [...]

The pxlBlck_RingClock is very similar to the pxlBlck_SlotClock. It is also built with the help of a 1×60 LED matrix and can display the time according to the same scheme as the pxlBlck_SlotClock. However, the [...]

The pxlBlck_8x8 was one of the first members of the pxlBlck family. Thanks to the few parts and the prefabricated WS2812 8×8 LED matrix it is quite fast to build and thanks to the adapter board it offers [...]

I started developing the pxlBlcks because I was looking for a way to stay informed about events in the SmartHome. In the meantime there are two in [...]

The pxlBlck-plugin for the ESPEasy framework is the "software counterpart" to the pxlBlck platforms. With the plugin you can easily control the installed LED matrices and with the help of the other functions is relatively [...]
WeiterlesenThe pxlBlck-plugin or the functions of your pxlBlck can be configured in two different ways. One way is to configure most of the functions via the plugin's web menu. Many infos [...]

With the help of pxlBlck you can be informed about events in different ways. One of these ways is to display previously set icons. Unfortunately this possibility [...]

The adjustable dials differ from the type of LED matrix used. Unfortunately, this is because different matrix sizes allow or do not allow different displays. Nevertheless, to give you a small overview [...]

If you not only want to stay informed about events with your pxlBlck and also use it to display the current time, then you may have already noticed that a fixed [...]

Thanks to WiFi and thus (often) also Internet connection, an ESP8266 or ESP32 programmed with ESPEasy also has the possibility to display the time. For this to work, the call [...]
