VL53L3CX Time-of-Flight Multi-Target Distance Sensor Carrier with Voltage Regulator, 500cm Max Category_Gearmotors/30mm Diameter Encoder allowing for an unregulated input

allowing for an unregulated input voltage to be supplied on the VIN pin to make the allowable input voltage range 7–16V

Datasheet (MPU-9250)

Bring your own Pi 4

Two of these ICs allow you to split a stereo audio input into 7-bands (per channel) and read the amplitude of each using the ADC on your Arduino

You can do all sorts of stuff with the audio as well such as adjusting bass

VL53L3CX Time-of-Flight Multi-Target Distance Sensor Carrier with Voltage Regulator, 500cm Max Category_Gearmotors/30mm Diameter Encoder allowing for an unregulated inputThis sensor is a carrier breakout board for STs VL53L3CX laser ranging sensor, which offers fast and accurate ranging up to 5 m. It uses the time of flight (ToF) of invisible, eye safe laser pulses to measure absolute distances to multiple targets simultaneously, independent of ambient lighting conditions and target characteristics like color, shape, and texture (though these things will affect the maximum range). Distance measurements can be read
