    ESP8266 and ESP32 – the main differences

    ESP8266 and ESP32 are the next best thing that happened to DIY world since Arduino itself. Thanks to development boards based on those MCUs brand new possibilities opened in front of all DIY and tinkering enthusiasts. With those two, not only we have cheap and powerful microcontrollers, but we can also make them talk to…

  • ESP8266 and DS18B20 – wireless ThingSpeak sensor

    Here is another small project of mine: battery operated ESP8266 ESP-01 WiFi thermometer using DS18B20 and ThingSpeak API to collect data. Before we proceed, you should:

  • ESP8266 ESP-01 Low Power Mode – run it for months

    Amazing ESP8266 ESP-01 WiFi boards have pretty irritating problem: theirs power consumption is pretty high.
