This easy project combines an Arduino with our microphone amplifier and bicolor LED matrix to create a music visualizer that responds to ambient sound.
Step 2: Arduino Library The LED matrix is controlled from the MAX7219 chip through an Arduino Library. This instructable is based on the LEDControl library. You can read a very clear and detailed tutorial about this library atarduino playground. The nice thing about this library is that you c...
If you already have the Adafruit Unified Sensor library installed then the installation of the AM2320 library will proceed. If you don’t have the Adafruit Universal Sensor Library installed you’ll be prompted to install it along with the AM2320 Library. Choose this option and both libraries ...
