+# ACTAM - Embedded programming with Advanced tools
+## 12/12/2024
+
+---
+
+## Goals: Introduce two new tools
+
+1) Arduino
+2) SuperCollider
+
+---
+
+## What is Arduino?
+* An open-source electronics platform combining hardware and software
+* Perfect for interactive music and sound projects
+* Check these out https://www.arduino.cc/education/arduino-instruments/
+
+--
+
+### Available Boards
+https://www.arduino.cc/en/hardware 
+* **Arduino Uno**: Basic board, good for simple audio projects
+* **Arduino Due**: 
+  - 12-bit DAC (Digital to Analog Converter)
+  - Higher processing power (84 MHz)
+  - Ideal for complex audio synthesis
+* **Arduino Mega**: More I/O pins for multiple controllers/sensors
+
+--
+
+## How can I program it?
+
+Get started with [this IDE](https://docs.arduino.cc/software/ide-v2/tutorials/getting-started-ide-v2/)
+* Built-in examples and library manager
+* Key audio libraries:
+  - `Tone`: Basic frequency generation (e.g. Pulse Width Modulation)
+  - `Mozzi`: Advanced audio synthesis (e.g. Algorithmic music)
+  - [Arduino Audio Tools](https://github.com/pschatzmann/arduino-audio-tools) for multiple effects and audio formats
+
+* A good way to start: https://www.tomshardware.com/how-to/use-arduino-ide-2
+
+-- 
+
+## Basic tone generation
+
+```cpp
+const int speakerPin = 9;
+void setup() {
+  pinMode(speakerPin, OUTPUT);
+}
+
+void loop() {
+  tone(speakerPin, 440, 500);
+  delay(1000);
+}
+```
+
+## Mozzi Library Example
+Advanced synthesis using the Mozzi library:
+
+--
+
+## Arduino as MIDI Controller
+```cpp
+void setup() {
+  Serial.begin(9600);
+}
+void loop() {
+  int sensorValue = analogRead(A0);
+  // Map sensor to MIDI values (0-127)
+  byte midiValue = map(sensorValue, 0, 1023, 0, 127);
+  Serial.write(midiValue);
+  delay(10);
+}
+```
+--
+
+## Arduino with Web Audio API
+```javascript
+// Receiving Arduino data via Web Serial API
+async function connectArduino() {
+  const port = await navigator.serial.requestPort();
+  await port.open({ baudRate: 9600 });
+
+  const reader = port.readable.getReader();
+  while (true) {
+    const { value, done } = await reader.read();
+    if (value) {
+      oscillator.frequency.value = value * 10;
+    }
+  }
+}
+```
+-- 
+
+## What's SuperCollider? Isn't SonicPi enough?
+
+* lower level language (SCLang)
+* real-time audio server (spectral analysis, manipulation, and resynthesis with FFT)
+* can define your own synthesis algorithms
+
+-- 
+
+### Basic SuperCollider Syntax
+
+```supercollider
+(
+SynthDef(\simpleSine, {
+    arg freq = 440;
+    var sig = SinOsc.ar(freq, 0, 0.5);
+    Out.ar(0, sig); //  precise channel mapping
+}).add;
+)
+
+// Play the synth
+x = Synth(\simpleSine);
+x.set(\freq, 880);
+x.free; // Stop
+```
+
+-- 
+
+### SuperCollider getting Arduino Data
+
+```supercollider
+SerialPort.listDevices; // List available ports
+
+p = SerialPort.new("/dev/ttyACM0", 9600);
+
+// Read incoming data
+r = Routine({
+    var byte;
+    loop {
+        byte = p.read;
+        // Map byte to frequency (example)
+        {SinOsc.ar(byte * 10)}.play;
+        0.01.wait;
+    }
+}).play;
+```
+
+### Arduino Code for SuperCollider
+Same as for web audio api 
+
+```cpp
+const int sensorPin = A0;
+
+void setup() {
+  Serial.begin(9600);
+}
+
+void loop() {
+  int sensorValue = analogRead(sensorPin);
+  Serial.write(map(sensorValue, 0, 1023, 0, 255));
+  delay(10);
+}
+```
+

+
+## Project Ideas & Applications
+You can create:
+* Interactive sound installations
+* MIDI controllers
+* Gesture-controlled synthesizers
+* Real-time audio effects processors
+* Sensor-based music generators
+* Interactive performance tools
