Envelope (Music)
In sound and music, an envelope describes how a sound changes over time. It may relate to elements such as amplitude (Volume), frequencies (with the use of filters) or pitch. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero.
Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments. The most common form of envelope generator is controlled with four parameters: attack, decay, sustain and release (ADSR).
A Simple ADSR Envelope Generator
This implementation has separate update() and next() methods, where next() interpolates values between each update(). The “normal” way to use this would be with update() in updateControl(), where it calculates a new internal state each control step, and then next() is in updateAudio(), called much more often, where it interpolates between the control values. This also allows the ADSR updates to be made even more sparsely if desired, eg. every 3rd control update.
noteOn()
Start the attack phase of the ADSR. This will restart the ADSR no matter what phase it is up to. True, the envelope will start from 0, even if it is still playing, often useful for effect envelopes. If false, the envelope will start rising from the current level, which could be non-zero, if it is still playing, most useful for note envelopes.

Harmonics – Brightness
Nearly all signals contain energy at harmonic frequencies, in addition to the energy at the fundamental frequency. If it contains all the energy in a signal at the fundamental frequency, then that signal is a perfect sine wave. If the signal is not a perfect sine wave, then some energy is contained in the harmonics. Some waveforms contain large amounts of energy at harmonic frequencies.
Ratio
So in the harmonic series, we have a fundamental (pitch/note) and a succession of harmonics that stem from the fundamental which also hold other pitches within themselves.
Arduino – Map
map(value, fromLow, fromHigh, toLow, toHigh)
Re-maps a number from one range to another. That is, a value of fromLow would get mapped to toLow, a value of fromHigh to toHigh, values in-between to values in-between, etc…

SparkFun Solderable Breadboard – Large
This is the Large SparkFun Solderable Breadboard. A bare PCB that is the exact size as our full-size breadboard with the same connections to pins and power rails. This board is especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place. The large solderable breadboard also includes real estate for screw terminal connectors and a trace down the center gutter for ground.

UltrasonicSynth Mozzi
Oscil
Oscil plays a wavetable, cycling through the table to generate an audio or control signal. The frequency of the signal can be set or changed, and the output of an Oscil can be produced with for a simple cycling oscillator, or for a particular sample in the table.
Soundtables
Look-up-tables and python scripts to generate tables or convert sounds. Includes ready-to-use wave tables and a few example samples. Also check out the other scripts in the python folder for templates to use if you want to do your own thing.
Smooth
A simple infinite impulse response low pass filter for smoothing control or audio signals. Smoothness sets how much smoothing the filter will apply to its input. Use a float in the range 0 – 1, where 0 is not very smooth and 0.99 is very smooth.
AutoMap
Automatically map an input value to an output range without knowing the precise range of inputs beforehand.

MicroSD Card Breakout Board+
Not just a simple breakout board, this microSD adapter goes the extra mile designed for ease of use.
- Onboard 5 Volt – 3 Volt regulator provides 150mA for power-hungry cards.
- 3 Volt level shifting means you can use this with ease on either 3 Volt or 5 Volt systems.
- Uses a proper level shifting chip, not resistors, less problems, and faster read/write access.
- Use 3 or 4 digital pins to read and write 8 Gb of storage.
- Activity LED lights up when the SD card is being read or written.
- Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove.
- Comes with 0.1″ header, unattached, so you can get it on a breadboard or use wires your choice.
To use with an Arduino, connect GND to ground, 5 Volt – 3 Volt to 5 Volt – 3 Volt, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10. Then you can use the Arduino IDE’s SD library which supports FAT and FAT32 SD cards.

DS3231 Precision RTC FeatherWing
A Feather board without ambition is a Feather board without FeatherWings. This is the DS3231 Precision RTC FeatherWing it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO). This RTC is the most precise you can get in a small, low power package.
Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that’s all well and good, but those crystals have slight drift, particularly when the temperature changes, the temperature changes the oscillation frequency very very very slightly but it does add up. This RTC is in a beefy package because the crystal is inside the chip, and right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule.
With a CR1220 12mm coin cell plugged into the top of the FeatherWing, you can get years of precision time keeping, even when main power is lost. Great for datalogging and clocks or anything where you need to really know the time.

ams CCS811 Ultra-Low Power Digital Gas Sensor for Monitoring Indoor Air Quality
The CCS811 is an ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor to detect a wide range of Volatile Organic Compounds (VOCs) for indoor air quality monitoring with a microcontroller unit (MCU), which includes an Analog-to-Digital converter (ADC), and an I²C interface.
CCS811 is based on ams unique micro-hotplate technology which enables a highly reliable solution for gas sensors, very fast cycle times and a significant reduction in average power consumption. The integrated MCU manages the sensor drive modes and raw sensor data measured while detecting VOCs. The I²C digital interface significantly simplifies the hardware and software design, enabling a faster time to market.
CCS811 supports intelligent algorithms to process raw sensor measurements to output a TVOC value or equivalent CO2 (eCO2) levels, where the main cause of VOCs is from humans. CCS811 supports multiple measurement modes that have been optimised for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications.
Applications
This device can be mainly used for indoor air quality monitoring in:
- Smartphones
- Wearables
- Home and building automation
- Accessories

Bosch Sensortec BME280 – Combined Humidity And Pressure Sensor
The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. The BME280 is register and performance compatible to the Bosch Sensortec BMP280 digital pressure sensor. The BME280 achieves high performance in all applications requiring humidity and pressure measurement. These emerging applications of home automation control, in-door navigation, E-Textiles, fitness as well as GPS refinement require a high accuracy and a low TCO at the same time. The humidity sensor provides an extremely fast response time for fast context awareness applications and high overall accuracy over a wide temperature range. The integrated temperature sensor has been optimized for lowest noise and highest resolution. Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature. The sensor provides both SPI and I²C interfaces.
Typical Application
- Context awareness, e.g. skin detection, room change detection
- Fitness monitoring / well-being
- Warning regarding dryness or high temperatures
- Measurement of volume and air flow
- Home automation control
- Control heating, venting, air conditioning (HVAC)
- Internet of Things
- GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
- Indoor navigation (e.g. change of floor detection, elevator detection)
- Outdoor navigation, leisure and sports applications
- Weather forecast
- Vertical velocity indication (rise/sink speed)
- E-Textiles and Wearable
Target Devices
- Handsets such as mobile phones, tablet PCs, GPS devices
- Navigation systems
- Gaming (e.g flying toys)
- Camera (DSC, video)
- Home weather stations
- Flying toys
- Watches
- E-Textiles
- Wearable

SparkFun Micro OLED Breakout (Qwiic)
The SparkFun Qwiic Micro OLED Breakout is a Qwiic-enabled version of our popular Micro OLED display. The small monochrome, blue-on-black OLED screen presents incredibly clear images for your viewing pleasure. It’s micro, but it still packs a punch the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next project and displaying diagnostic information without resorting to a serial output, all with the ease of use of our own Qwiic Connect System.
This version of the Micro OLED Breakout is exactly the size of its non-Qwiic sibling, featuring a screen that is 64 pixels wide and 48 pixels tall and measuring 0.66 inch across. But it has also been equipped with two Qwiic connectors, making it ideal for I2C operations. We’ve also added two mounting holes and a convenient Qwiic cable holder incorporated into a detachable tab on the board that can be easily removed thanks to a v-scored edge. We’ve even made sure to include an I2C pull-up jumper and ADDR jumper on the back of the board, so if you have your own I2C pull-ups or need to change the I2C address of the board, you have options.
