Momentary Button – Panel Mount

It’s your basic black or blue action button. This is a very useful, small, panel-mount momentary switch. It is a SPST N.O. with the threaded portion being 6.75 mm in diameter. This button is perfect for basic On/Off functions. Overall length including leads and has small solder lugs for connection. These momentary buttons are rated up to 0.5A and 250VAC.

Momentary button connect two points in a circuit when you press them. Turns on and off a light emitting LED. When the button is open there is no connection between the two legs of the button, so the pin is connected to ground, through the pull-down resistor, and we read a LOW. When the button is closed, it makes a connection between its two legs, connecting the pin to 5 volts, so that we read a HIGH.

You can also wire this circuit the opposite way, with a pullup resistor keeping the input HIGH, and going LOW when the button is pressed. If so, the behavior of the sketch will be reversed, with the LED normally on and turning off when you press the button.

10k Ohm Slide Linear Taper Pot – X-Large

A simple slide potentiometer can go a long way. Rated at 10k Ohm and 0.5W. Comes with solder tab connections. The taper profile for this slide:

Length: 80 cm
Width: 15 cm
Height: 12 cm

Slide Potentiometer Knob – X-Large

This is a simple knob that connects to the extra large sized linear slide potentiometer. Each knob uses friction to secure itself to fit onto the slide pot. Once attached, this small knob provides you with an easier to use potentiometer for your project.

Adafruit METRO M0 Express

Metro is our series of microcontroller boards for use with the Arduino IDE. This new Metro M0 Express board looks a whole lot like our original Metro 328, but with a huge upgrade. This Metro features a ATSAMD21G18 chip, an ARM Cortex M0+.

At the Metro M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic. This chip has a 256K of FLASH and 32K of RAM. This chip comes with built in USB so it has USB-to-Serial program.

Volume Sound

Volume the degree of loudness or the intensity of a sound. The volume of a sound is how loud or quiet the sound is. Sounds are vibrations that travel through the air. Volume, or loudness, is related to the strength, intensity, pressure, or power of the sound. Amplified vibrations result in louder sounds. There are a few ways of varying the volume.

I am using the Mozzi audio library to implement a simple synthesizer and using a potentiometer to control the amplitude of a sinewave with Mozzi sonification library. To convey the volume level. Volume it to an 8 bit range for efficient calculations.

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.
