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 More
This project is to give a practical example of using power save modes with Arduino's. It uses a Real Time Clock (RTC) to wake up an Arduino Data Logger. It write the temperature and humidity in a room to a micro SD card. It is optimized for saving power thus can run of a battery pack.Read More
A couple of year’s back I bought one of the Neopixel light strings from Adafruit. I think it was 200 leds. I used them one season and put them away. This Christmas I decided to make an IOT Christmas light display out of it just above our horizontal blinds.
To do this I used the code explained in the Tutorial:Storing WiFi Configuration On Your ESP8266 Using The EEPROM Library Made Simple Part 1 and Tutorial part 2. I also used code from the Adafruit Neopixel example code and integrated it with my base code to create an IOT device from the tutorial.Read More
