The "Guru Meditation Error Core ,.." message is a common indication of an unexpected crash on the ESP32 chip's Core 1. It's not the most helpful error message, but with some investigation, you can usually diagnose and fix the cause.
This error appear after test program or change script
Specially command for(;;){
The function for(;;){} in an Arduino program script defines an infinite loop. This means the code inside the curly braces will be executed repeatedly forever, until the board is reset or powered off.
Overall, the for(;;){} function is a powerful tool for creating continuous execution in your Arduino program. Use it wisely and responsibly!
Here's a breakdown of the function:
for: This keyword indicates the start of a loop.
(;;): This is the loop condition.
;;: These are empty semicolons, meaning the loop will always be true and never stop.
Monitoring sensors: You can use the loop to continuously read sensor values, display them on an LCD, or send them to a computer via serial communication.
Controlling LEDs or motors: The loop can be used to blink LEDs at a specific frequency, rotate a motor at a certain speed, or generate complex patterns.
Implementing background tasks: You can use the loop to run low-priority tasks like checking for button presses, playing sounds, or updating internal variables, while the main program handles other things.
