Sam Yannotti Final lab post

Objective: To create an Arduino based tone generator run with a passive low pass filter

Materials: Arduino Uno board & programming software, an unbelievable amount of wires, piezo buzzer (or a better pair of speakers), breadboard, variable resistors, 1uf capacitor


1) Find code for arduino tone generator

2) Install code on “arduino uno” motherboard

3) Install variable resistor to control pitch

4) Study passive LPF schematic

5) Configure breadboard to resemble schematic

6) Install variable resistor to control frequency range passing through the resistor

7) Make Ambient music ala Brian Eno

Results: A two knob hybrid synthesizer which can control pitch, and frequency range

Discussion: To be discussed tomorrow
