Philips Hue and ESP8266/ESP32 (part 2)
In this video, I would like to continue with the ideas of using the microcontroller and Philips Hue system. Let's see how to extend the light control capabilities with IR remote control (e.g. remote control from TV) or make an interactive switch with TFT shield for ESP32 Lolin D32 with simple power consumption monitoring.
Blue LED matrix display 8x16 for your Arduino
In this video I'd like to introduce an LED matrix display (8x16), for use in projects where a text-readable display is needed. Rendering of text is provided by 128 LEDs connected to 5V power supply in our demo on Arduino UNO (pins 2 and 8).
Capacitive Soil Moisture Sensor v1.2 with Wemos D1 Lite (Arduino IDE)
In this video I'd like to present you cheap chinese capacitive humidity sensor for Arduino or ESP. See quick setup with Arduino IDE together with Wemos D1 Li...
How to store data in ESP8266 and ESP32 flash memory
In this video I would like to present several ways how to permanently store data on your microcontroller. I'll show you work with memory from the simplest way (writing using EEPROM library), writing to NVS on ESP32 to simple operations (create, append, read, remove file) in the SPIFFS file system on ESP8266 and ESP32 (the size of the memory is determined by the version of the board you own. In video you can see some of boards including the amount of usable memory)
Simple sensorless weather station, OpenWeatherMap API (part 1)
Do you want to build up weather station but you have no sensors or spot where to place them? This video shows basics how to create simple system connected to...
Sensorless weather station, OpenWeatherMap API (part 2)
This video is the second part of the topic of "Sensorless Weather Station". In this part we go to use newest Wemos Lolin D32 Pro and its touch TFT shield. For connection of display to the board we use Lolin connector and SD card together with build-in SD card slot as memory for icons stored as BMP.
BME680 (GY-MCU680V1) Indoor air quality meter
In this video we will introduce how to make a very simple air quality meter in a room. For this purpose, we use the GY-MCU680V1 sensor containing the BME680 chip from Bosch Sensortec. BME680 is a metal oxide-based sensor that detects VOCs by adsorption (and subsequent oxidation/reduction) on its sensitive layer.
