In this tutorial, we will learn how to use an external interrupt to wake up the ESP32 from a deep sleep. There are two external wake up resources available such as an ext0 and ext1. When the state of a GPIO pin is changed, the ESP32 will wake up from deep sleep. There are two … Read more
In this tutorial, we will learn to use ESP32 touch pins as a wake-up source from a deep sleep. First, we will put ESP32 into deep sleep mode and then see how to wake it up using touch sensor pins. When the ESP32 is in deep sleep, it consumes very low power, making it an … Read more
In this tutorial, we will learn to use Timer as a wake-up resource from a deep sleep. First, we will put ESP32 into deep sleep mode and then see how to wake it up using a predefined time using a timer. Recommended Components The following components are used in this project or are helpful for … Read more
