Hi,

I hope you are doing well. I’ve just added a new guide to the RNT Lab.

Here’s the direct link: ESP8266 Deep Sleep with Arduino IDE

In this guide, you’re going to learn what’s deep sleep and how to use it with the ESP8266 in the Arduino IDE.

If you’ve made a project with an ESP8266 board that is powered with a battery. Or, if you just connected your ESP NodeMCU board to a power bank. After running it for a while, you realize that the battery doesn’t last very long.

With most of these ESP8266 modules, you can’t change the hardware to save power, but you can write software. If you use the sleep functions with the ESP8266, it will draw less power and ultimately your batteries will last longer. In this guide, we’re going to talk about deep sleep with the ESP8266.

Thanks for reading,

Rui
