I am still receiving many requests to post an Arduino Sound Machine project. I think now is the right time to prepare a primer for beginners. First, keep your expectations low, as I don’t have ...

If you can't get the module to initialize properly, try the following: Make sure your DPPlayer and your Arduino board share a common negative. Without the common negative, the current will not flow ...

A 1kΩ resistor is put in between the Arduino digital pin 9 and MP3 module's RX to drop the voltage down from the Arduino’s 5V. Programming Arduino Nano for Decorative Christmas Tree Once we are ready ...

void reset (bool waitForOnline = true, unsigned int timeout = 2000) Reset the hardware module. Calling this method will make the module not available for about one second and may cause noise in the ...

The build uses an Arduino, an MP3 chip, a SD card, LCD screen, amplifier, and two speakers. Everything is then packed into a small repurposed box with buttons and a volume knob. The end result is ...

The module relies on a PIC24F for input and control, while a VS1011 handles all of the MP3 decoding responsibilities. He says that the module would be great for voice-enabled vending machines ...

We can use the ADC of the Arduino to process the signal and we can light up some LEDs to show the intensity of the sound received by the microcontroller. The connection of the circuit is also very ...
