Goouuu esp32 fritz1/28/2024 ![]() ESP32 Interrupts and Timers with PIR Sensor using Arduino IDE.For more information refer to the following article: ![]() ![]() Therefore, you should initialize these pins to active-low state in the code in the setup function of the code.Īll above-mentioned GPIO pins can be configured in interrupt mode to detect positive edge, negative edge, or level triggered. The following pins will be in an active-high state by default during boot-up or reset. But it is recommended to keep it below 20mA.Īll GPIO pins on initial boot-up or reset remain in the active low state except the following pins. Note: The maximum operating current which GPIO pins can sink and source is 40mA according to the datasheet of ESP32 chip. Check this tutorial: How to use push button with ESP32
