Flashing the ESP8266 or ESP32 is not that easy if you have not had much contact with microcontrollers before. Now, there is something very cool that makes this process super […]
Read moreEspEasy and Node Red each offer a number of options for automation. You get even more options if you combine both systems. In the article ESPEasy – Execute commands and […]
Read moreI 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 […]
Read moreTo be honest, the idea of a 3D printable wind sensor (in technical jargon “anemometer”) has been floating around in my head for a long time. Initially I could have […]
Read moreThanks to the NTP server, ESPEasy is able to call up the time via the WiFi connection. This option is very easy to set up and is described, for example, […]
Read moreThe ButtonBoard PCB is my attempt to kill several birds with one stone. On the one hand, I’ve always been looking for a universal and easy-to-program remote control for the […]
Read moreThe idea for the pxlDigit_PCB came to me while building the first version of the pxlDigit (article here: https://nerdiy.de/en/howto-elektronik-sieben-segment-ziffer-pxldigit-aus-ws2812-leds-bauen/). The pxlDigit is built up from individual WS2812 LED segments. To […]
Read moreOne of my past PCB projects is the “pxlBlck_multiPCB”. As the name suggests, this board is the heart of several future pxlBlck variants. So far I have used the Wemos […]
Read moreMP3 players, smartphones and USB sticks with 128GB and more memory are now part of everyday life. Storing and transporting music has therefore never been easier. About 30 years ago […]
Read moreThe APDS-9960 is a sensor that can be connected to a microcontroller such as the ESP8266 via the I2C bus. With the help of the sensor it is possible to […]
Read moreI am not sure whether ESPs can really be abused to set up a botnet. Either way, you shouldn’t neglect the issue of security, even with the small ESPEasy devices. […]
Read moreThe VL53L0x or its sister / brother, the VL53L1X is a very precise and relatively inexpensive laser distance sensor. With this, distances can be measured almost at millimeter-accuracy. In one […]
Read moreThe BME280 is one of the sensors that I use in almost all of my projects. With this sensor one can not only measure the temperature. The air humidity and […]
Read moreESPEasy can read out a large number of different sensors and / or control actuators (see also ESPEasy – Sensors & Actuators). With the help of the “Rules” it is […]
Read moreEspecially if your own circuit has a display to show values, the next step is often to connect an interface option. You can connect buttons or switches. A relatively cool […]
Read moreThe PCA9685 is quite a practical IC. This is connected to the microcontroller (e.g. ESP8266) via I2C and can then control up to 16 individual PWM channels. You can control […]
Read moreThere 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 […]
Read moreI started with the documentation of the pxlBlcks (which I had been postponed for a too long time) in November 2020 after Hackaday.com had announced the “GoodBye 2020” challenge. (More […]
Read moreThe pxlBlck_RingClock is very similar to the pxlBlck_SlotClock. It is also built using a 1 × 60 LED matrix and can display the time according to the same scheme as […]
Read moreThe 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 set up fairly quickly […]
Read moreI 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. […]
Read moreThe pxlBlck plugin for the ESPEasy framework is the “software counterpart” to the pxlBlck platforms. With the plugin you can easily control the built-in LED matrices and with the help […]
Read moreThe pxlBlck plugin and the functions of your pxlBlck can be configured in two different ways. One possibility is to configure most of the functions via the plugin’s web menu. […]
Read moreWith the pxlBlck you can be informed about events in different ways. One of these possibilities is to be able to display previously set icons. Unfortunately, this option only works […]
Read moreThe 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 […]
Read moreIf you not only want to stay informed about events with your pxlBlck and also use it to display the current time, then it might be you noticed that a […]
Read morepxlBlck is a system of hardware and software to set up an information system for the SmartHome. Various software and hardware options are available. Thanks to the integration in an […]
Read moreThanks 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 […]
Read moreThe PCA9685 is a PWM port expander. This makes it possible to connect up to 16 LEDs, servos or other components to your ESP8266 and supply them with a PWM […]
Read moreI recently stumbled across the VL53L0X and VL53L1X TOF distance sensors. These sensors can determine distances with millimeter accuracy using a laser. In addition, they have a range of up […]
