# Oscillator Modules
## What's an oscillator?
Every synthesizer needs an oscillator. An oscillator is a circuit that takes a steady signal (e.g. from a battery) and turns it into an oscilllating (changing / moving up and down) signal.

## Wendy: the NOT gate
The heart of the Wendy is a CD40106 IC, which is a logic chip containing 6 inverters / NOT gates.

* Delia: The phase-locked loop
## Delia: the phase-locked loop
The Delia oscillator is a little more complex. Link to Hackaday?
# Other modules
## Ada
* Maryam: space-filling curves
* Filter
## Maryam
* Volume
The Maryam module works with the Wendy module
*When not touched, no current flowing through oscillator, no sound
* When touched, intensity of touch determines pitch
* Ada
The design of the Maryam module is a Hilbert curve. Read more in my project diary (link) about this
