ESP32 NTP OLED clock

@ blog.danman.eu build a OLED display NTP clock and document his process on his blog:

As a first project with my new ESP32 module with OLED display I chose to build OLED clock. I thought I’ll just find some existing code, upload it and it’s done. There are a few such projects for ESP8266 in NodeMCU. So I started with NodeMCU upload.

Running NodeMCU on a battery

ESP8266 low power consumption revisited:

Using Wi-Fi is a convenient way to link your newly created IoT device into your existing IT infrastructure – including cloud services – but it also has a drawback. Wi-Fi’s demand for power usually makes battery operation impractical for any real deployment. I have been able to get around this issue for most of my projects (e.g. the train and the smart shelf described on this blog) because they are for demonstration purposes only, requiring the battery to last no longer than a few hours.

user Ingenerare @ instructables.com published a tutorial on a IoT weather station based on NodeMcu board, DHT11/22 sensor, BMP180 sensor, Rain sensor, Light sensor.

In this tutorial, I will walk you through the steps to build an easy and cheap IOT weather station. The retrieved data is pushed via a wifi shield to Thingspeak. The data can be analysed on the Thingspeak channel or on a personal website as can be seen in the pictures above.

In this article Rui Santos help us solve the main issues that may arise when trying to flash a new firmware or uploading scripts on ESP8266 Wifi module. He discuss about NodeMCU flasher and how to use it successfully and also he discuss about ESPlorer IDE and it’s use.

Get Started with ESP8266 Using AT Commands, NodeMCU, or Arduino (ESP-12E)

This Instructable will show you the steps needed to get started with the ESP8266 using a fantastic little development board for the ESP-12E module. The board includes everything needed including a USB to Serial adapter, surface-mount LED, and voltage regulator. In addition, it is easily mountable on a breadboard for developing your own IoT project(s)!

The main goal of the Instructable is to cover all the different options you can use in terms of firmware for developing applications that use the ESP8266 to connect to the web. The content, although available, is scattered throughout various sites around the web thus we decided to condense it in one place.
