ESP32 Interrupt Tutorial Interrupts are used to handle events that do not happen during the normal execution of a program, but when a specific trigger occurs. For example, if we write a program to blink an LED, the microcontroller will execute each command one by one. But if we want to monitor a switch to start or stop the blinking, it will only be possible after all other tasks before the… |
