Laser modules emit highly focused beams of light, making them ideal for a wide range of applications. One of the key aspects of a laser module is its power output, typically measured in milliwatts (mW). Arduino compatible laser modules typically have a power output within the lower range ensuring safety and compatibility with the microcontroller board. It's important to note that modules require safety precautions due to their increased risk of eye damage and potential fire hazards for higher-power lasers.

It's not possible to make a direct MP3 to buzzer decoder because a buzzer (especially a typical piezo buzzer) can only produce simple tones at specific frequencies, not complex audio like speech or music. MP3 files contain compressed, multi-frequency audio data far beyond what a buzzer can reproduce. At best, you could extract a basic melody or rhythm if the MP3 is extremely simple (like single-tone music), but decoding full MP3 audio into something a buzzer can play accurately isn't feasible.

HiBit

Thank you, very appreciated!

The issue is likely that the MPU6050 isn't properly initialized after power-up. Make sure the setup() function runs completely each time the device is powered on, and consider adding a small delay before using the sensor.

The Doom melody requires more memory than others, so make sure your board can handle that amount. If not, you will usually encounter an error during compilation.

As a workaround, you can try removing some of the notes (along with their respective durations) to fit the melody on the board.
