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.

Theremin

The theremin was invented in 1920 by a Russian physicist named Lev Termen. Today, this marvelous instrument is once again in the musical spotlight. Besides looking like no other instrument, the theremin is unique in that it is played without being touched.

Two antennas protrude from the theremin, one controlling pitch, and the other controlling volume. As a hand approaches the vertical antenna, the pitch gets higher. Approaching the horizontal antenna makes the volume softer. Because there is no physical contact with the instrument, playing the theremin in a precise melodic way requires practiced skill and keen attention to pitch. The electric signals from the theremin are amplified and sent to a loudspeaker.

In the late 1920’s, RCA produced approximately 500 theremins, manufactured by General Electric and Westinghouse. Today, it is estimated that only half of these still exist. The spooky sound of the theremin was used in several movie soundtracks during the 1950’s and 1960’s. Electronic music pioneer Robert Moog built theremins long before he built synthesizers. In the 1960’s, he produced such models as the wedge-shaped Vanguard theremin and the shoebox shaped Moog Melodia theremin. It provided background mood music for such sci-fi classics. During the 60’s and 70’s, bands such as Lothar and the Hand People, the Bonzo Doo Dah Dog Band, and Led Zeppelin brought the theremin into the public eye for a short time.

Theremin + Arduino Pro Mini + Ultrasonic Sensor + Mozzi

Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. This is the ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality. The ultrasonic range detectors replace the antenna of the traditional Theremin. Control the frequency (pitch) of the output. Operation of the sensor is straightforward. The Arduino sends a digital pulse to the TRIG pin of the sensor causing it to emit a burst of high frequency audio. If an echo is detected the sensor toggles the ECHO pin which is monitored by the Arduino. By measuring the time delay between the outgoing pulse and returning echo we can calculate the distance. As sound takes 29 microseconds to travel one cm, and must travel out and back, we can divide the time to the echo by 5.8 to get the distance in mm. The project uses the Mozzi audio library to generate a sine table for oscillator which is sent to the output.

LiPower Boost Converter

The LiPower board is based on the incredibly versatile TPS61200 boost converter. The board is configured to be used with a LiPo battery, has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V. However, the board can also be used as a general purpose buck and boost regulator with an input voltage as low as 0.3V. With such a low input voltage and quiescent current, the board also works well in energy harvesting applications that use low input voltages.

XBee Explorer Regulated

The XBee Explorer Regulated takes care of the 3.3V regulation, signal conditioning, and basic activity indicators. It translates the 5V serial signals to 3.3V so that you can connect a 5V system to any XBee module. The board was conveniently designed to mate directly with Arduino Pro boards for wireless bootloading and USB based configuration. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro versions. Plug an XBee into this breakout and you will have direct access to the serial and programming pins on the XBee unit and will be able to power the XBee with 5V.

ChronoDot – Ultra-Precise Real Time Clock – v2.1

The ChronoDot RTC is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC. It includes a CR1632 battery, which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required.

The top side of the Chronodot now features a battery holder for 16mm 3V lithium coin cells. It pairs particularly well with CR1632 batteries. The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continously monitored, and the capacitors are adjusted to maintain a stable frequency. Other RTC solutions may drift minutes per month, especially in extreme temperature ranges…the ChronoDot will drift less than a minute per year. This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock.

RGB LCD Shield 16×2 Character Negative Display

With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino. The shield is designed for Arduinos Uno. It uses the I2C pins at Analog 4 and Analog 5.

At this time, the library and shield can control the RGB backlight of our character LCDs by turning each LED on or off. This means you can display the following colors: Red, Yellow, Green, Teal, Blue, Violet, White and all off. This shield is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.

Adjusting Contrast

The shield uses a character LCD with an external contrast potentiometer. The first time you use it, adjust the potentiometer in the bottom right until you see the text clearly.

Adafruit PowerBoost 500 Shield – Rechargeable 5V Power Shield

What’s a project if it’s trapped on your desk? Now you can take your Arduino anywhere you wish with the PowerBoost shield. This stackable shield goes onto your Arduino and provides a slim rechargeable power pack, with a built in battery charger as well as DC/DC booster.

Compatible with Arduino Uno basically any Arduino-pinout-shaped Arduino as only the GND and 5V pins are used. You can stack shields on top, or stack the PowerBoost on top. The PowerBoost shield can run off of any Lithium Ion or Lithium Polymer battery but we suggest our 2000mAh capacity batteries, both of which fits very nicely in the empty space of the shield. Plug in the battery and recharge it via the microUSB jack. When you’re ready to go, just unplug the Arduino from USB or the wall adapter and it will automatically switch over to shield power. Use only Lipoly batteries with protection circuitry.

The onboard boost converter can provide at least 500mA current, and can peak at 1A. There’s an onboard fuse to protect against higher current draws which could damage the boost converter or battery. The boost converter can be damaged by high current spikes and is not recommended for driving motors or robots where the stall current can cause high current spikes. It will let you turn the shield and Arduino power on/off.

Lithium Ion Battery – 3.7v 2000mAh

Lithium ion polymer batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. If you need a larger battery. The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.
