It is able to read the incoming audio signal and create effects on the four 8&#215;8 LED matrices. The project is Open Source and aimed for hackers, musicians and programmers that want to learn about\u00a0DSP (digital signal processing), LEDs, guitar effects, and experiment without deep knowledge\u00a0on electronics or programming.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/IUKeNdt1Qo0\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-mce-fragment=\"1\"><\/iframe><\/p>\n<p><strong>Arduino Audio Meter Specifications:<\/strong><\/p>\n<ul>\n<li>Based on Arduino UNO board for signal processing (16MHz, 1KB RAM).<\/li>\n<li>Analog input\/output stages using MCP6002 rail to rail op-amp.a<\/li>\n<li>The original audio signal passes though the pedal without suffering any modification.<br \/>\nInterface:<\/p>\n<ul>\n<li>1 Gain knob (amplifies the guitar signal that goes into the arduino for better resolution)<\/li>\n<li>1 Encoder knob + Push-Button (programmable by the user)<\/li>\n<li>4 LED matrix 8&#215;8 (driven by four MAX7219)<\/li>\n<\/ul>\n<\/li>\n<li>Connectors:\n<ul>\n<li>Input Guitar Jack, 1\/4 inch unbalanced mono, Zin=1M\u03a9.<\/li>\n<li>Output Guitar Jack, 1\/4 inch unbalanced mono, Zout=0.1\u03a9.<\/li>\n<\/ul>\n<\/li>\n<li>Power supply:\n<ul>\n<li>Any supply from 9 to 12V.
