Arduino Shield sensors and sound

Sound plays a very important role in both industrial and home use – also those about the quality of the entertainment. The alarm sound is very often used in alarms with tamper protection, and warning systems that use sensors that are designed to signal the occurrence of the hazards in the workshop or in its vicinity. In turn to play music and record sound involving digital technology, you should pay attention to the selection of the appropriate equipment that will allow us a very good quality file, as in the process of recording and reading audio. Botland store offers special pads Arduino Shield, with which you will be able to implement most of the tasks described above.

A feast for music lovers with overlays for Arduino Shield

Add the ability to play music or sound effects for Your project can be an interesting variety, which will deliver attractive and attract the attention of the audience. Using Arduino and special pads, you can play audio files in popular formats such as MP3, WAVE or WMA. Pad Waveshare VS1053B MP3 Music Shield is great for this option. Just insert SD card and connect the module with external speakers or headphones. Using buttons and potentiometers, you can select files for playback, and adjust the audio settings such as volume or gain of individual frequency bands. And overlay KIT MIDI Shield from SparkFun will allow You to build a sound synthesizer and sequencer cancer. The concert on your instrument? Invaluable experience!

Simple sound alarm

In addition to musical applications, using overlay audio Arduino Shield you will be able to create an extensive system of sensors with an audible alarm that will alert you, for example, if in the air there are harmful gases or will set in motion a gate with electric drive. Connecting the microphone to shielda, you will be able to build a comprehensive system of building automation, where control of roller blinds and lighting will be contactless. Will be carried out through commands issued by the voice.
