Description: The SparkFun MIDI Shield board gives your Arduino access to the antiquated, but still widely used and well supported MIDI communication protocol, so you can control synthesizers, sequencers, and other musical devices. The MIDI protocol shares many similarities with standard asynchronous serial interfaces, so you can use the UART pins of your Arduino to send and receive MIDI’s event messages.

The MIDI Shield provides an opto-isolated MIDI-IN port as well as a MIDI-OUT port. The MIDI Shield can be mounted directly on top of an Arduino, connecting the MIDI-IN to the Arduino’s hardware RX pin and the MIDI-OUT to TX. Potentiometers are connected to analog pins 1 and 2, and can be used to control volume, pitch, tone or anything else you’d like. Also connected on the shield are three momentary push buttons (connected to D2-4), a reset button, and green and red stat LEDs. The RUN/PROG switch allows you to program the Arduino over serial without having to remove the shield.

Note: The MIDI Shield does not come with the through-hole MIDI connectors or trimpots soldered on. All of these components (2 MIDI connectors and 2 trimpots) are included with the product, however

Note: When using this shield with the Arduino Pro you will have to bypass the TX/RX resistors on the Pro to get enough current to the shield.

Description: Riding on the waves of the very popular Arduino USB board is this small prototyping shield. Originally spawned with collaboration between the folks at SFE and ITP @ NYU, the ProtoShield mates with the Arduino USB board and gives the user a small soldering area, two general LEDs, access to a BlueSMiRF socket, a general pushbutton switch, and most important of all – the Arduino reset switch is brought to the top level. A ProtoShield quickstart guide is available!

This comes in kit form and must be soldered together by the end user. Please note – we do not ship assembly instructions, but you can find a big, clean photographed assembly guide here! There are a few tutorials on assembly listed below. All soldering is through-hole (relatively easy) but always check your component orientation before soldering!

The kit is pictured with the bread-board option. We highly recommend this breadboard! See the related items below for all the colorful options of breadboards you have.

Description: This is a breakout board for the incredibly small TMP102 digital temperature sensor. The TMP102 is a digital sensor (I2C a.k.a. TWI), has a resolution of 0.0625°C, and is accurate up to 0.5°C. The sensor requires very low-current, and is loaded with features.

Communication with the TMP102 is achieved through a two-wire serial interface. There is no on-board voltage regulator, so supplied voltage should be between 1.4 to 3.6VDC. Filtering capacitors and pull-up resistors are included as shown.

Features:

• 12-bit, 0.0625°C resolution
• Accuracy: 0.5°C (-25°C to +85°C)
• Low quiescent current
10µA Active (max)
1µA Shutdown (max)

Description: This is a breakout board for Honeywell’s HMC5883L, a 3-axis digital compass. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied.

The breakout board includes the HMC5883L sensor and all filtering capacitors as shown. The power and 2-wire interface pins are all broken out to a 0.1″ pitch header.

Features:

• Simple I2C interface
• 2.16-3.6VDC supply range
• Low current draw
• 5 milli-gauss resolution

Dimensions: 0.7×0.7″ (17.78×17.78mm)

Description: This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.

This breadboard friendly board breaks out every pin of the MMA7361L to a 9-pin, 0.1″ pitch header. The sensor works on power between 2.2 and 3.6VDC (3.3V optimal), and typically consumes just 400µA of current. All three axes have their own analog output.

Features:

• Two selectable measuring ranges (±1.5g, ±6g)

Description: This is a breakout board for InvenSense’s ITG-3200, a groundbreaking triple-axis, digital output MEMS gyroscope. The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface. Additional features include an embedded temperature sensor and a 2% accurate internal oscillator.

The ITG-3200 can be powered at anywhere between 2.1 and 3.6V. For power supply flexibility, the ITG-3200 has a separate VLOGIC reference pin (labeled VIO), in addition to its analog supply pin (VDD) which sets the logic levels of its serial interface. The VLOGIC voltage may be anywhere from 1.71V min to VDD max. For general use, VLOGIC can be tied to VCC. The normal operating current of the sensor is just 6.5mA.

Communication with the ITG-3200 is achieved over a two-wire (I2C) interface. The sensor also features a interrupt output, and an optional clock input. A jumper on the top of the board allows you to easily select the I2C address, by pulling the AD0 pin to either VCC or GND; the board is shipped with this jumper tied to VCC. If you don’t plan on using the CLKIN pin, you can short the jumper on the bottom of the board to tie it to GND.

This breakout board is shipped as shown in the images. Note that there are two unpopulated resistors on the I2C lines, these can be added later by the customer if desired.

Features:

• Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit
• Digitally-programmable low-pass filter
• Low 6.5mA operating current consumption for long battery life
• Wide VDD supply voltage range of 2.1V to 3.6V
• Standby current: 5µA
• Digital-output temperature sensor
• Fast Mode I2C (400kHz) serial interface
• Optional external clock inputs of 32.768kHz or 19.2MHz to synchronize with system clock
• Pins broken out to a breadboard friendly 7-pin 0.1″ pitch header

Dimensions: 0.87 x 0.72″ (22.22 x 18.48mm)
