In this sample project we are going to build a NodeMCU data logger that uses the Adafruit cloud to store the temperature and humidity data. To make it even more exciting we are putting the NodeMCU to sleep in the periods that we are not transmitting the data to the cloud.
Read MoreThis tutorial is a simple guide to get started with the NodeMCU one of the most popular forms of the ESP8266 on the market right now. The NodeMCU is a powerful board that is good on the pocket book, but has its drawbacks. We are going to explore how to set this board up with the Arduino IDE, and some other simple tips and trick to get you started.
Read MoreA lot of makers don't know how important it is to know the current draw of your project, or why you need to know this. In this tutorial I will explain to you how to measure the current draw of your project, and why it is so important to know this.
I often get asked the question of what type of power supply to use for projects. Most of us know the voltage required, but how much current it draws and why you need to know this is a mystery to many beginner makers. To start with what is this current thing? "In comes the analogy that uses the flow of water to explain these things".
Read MoreThis is Part 2 of a 2 part tutorial that will simplify the way you can store your WiFi configuration on an ESP8266 using the EEPROM library. With this knowledge you can then build Internet Of Things (IOT) projects that can be configured by web form. This will enable to change passwords or IP configuration when needed without having to recompile your sketch.
In part 2 you will learn howto read information "your stored in memory in part one" out of memory. How to use it to configure your IOT device to connect to your WiFi network, and make it user configurable by combining Part 1 and 2 in one sketch
Read MoreThis tutorial is part 1 of 2 that will simplify the way you can store your WiFi configuration on an ESP8266 using the EEPROM library. With this knowledge you can then build Internet Of Things (IOT) projects that can be configured by web form. This will enable to change passwords or IP configuration when needed without having to recompile your sketch.
In part 1 we learn how to write the information to your IOT project, part 2 will teach you how to read this information out of memory and configure your IOT project so it can connect to your WiFi router
