Nerdiy.com - Nerdy DIY HowTo's about electronic, 3D-printing and more.
Nerdiy.de is about electronics, DIY, 3D printing, smart home and a lot of other technical topics.
The Arduino category lists all articles that deal with the construction, operation and programming of Arduino microcontrollers.
I got the idea for the pxlDigit_PCB while building the pxlDigit (article here: https://nerdiy.de/howto-elektronik-seven-segment-digit-pxldigit-aus-ws2812-leds-bauen/). There the pxlDigit is made up of individual WS2812 LED segments. To do this, the LEDs […]

The 3D printed housing of the "pxlDigits" was initially not intended to be "just" a 7-segment display with WiFi. Originally I used it to build a kind of timer from […]

For another project I urgently needed a relatively large number to indicate a duration. From this this small "sub-project" emerged. Because with the 3D printed frame described here and a […]

There are some situations in which connecting an LDR to an ESP makes sense. In this way, the brightness in a room can be measured relatively easily and for little […]

The idea for the pxlBlck_Pot is heavily inspired by a design that Lukas (@i_am_lukas) had created. He agreed that I can use his basic design. Thanks again for that. 🙂 […]

The pxlBlck_SlotClock consists of a 1×60 LED matrix. It can display the time in the same way as an analog clock. The colors of the individual hands can be adjusted. […]
Weiterlesen
I started developing the pxlBlcks because I was looking for a way to stay informed about events in the SmartHome. There are now two options integrated into the pxlBlck plug-in. [...]

The adjustable dials differ from the type of LED matrix used. Unfortunately, this is the case because different LED matrix sizes allow or do not allow different dials and screensavers. In […]

Thanks to WiFi and thus (often) an internet connection, an ESP8266 or ESP32 programmed with ESPEasy also has the option to retrieve the actual time. In order for this to […]

One thing that makes ESPEasy so practical and universal is the ability to read and control various sensors and actuators via commands. Especially in combination with appropriate rules, this results […]
Weiterlesen
Each project consists not only of many important hardware components but also of the appropriate software. It is often less work to assemble the project than to write the appropriate […]
Weiterlesen
The great thing about the concept behind the Arduinos is that in many cases you can benefit from the work of others. It does not matter which sensor you read […]

In recent years, the ESP8266 has become more and more the universal microcontroller that can be used in almost any project. A microcontroller for ~2€ including Wi-Fi and with lots […]
Weiterlesen
Besides the hardware, the right software for your project is just as important. A practical and universally applicable firmware for the "forest-and-meadow microcontroller" ESP8266 is the Tasmota firmware. This allows […]
