| "Adafruit Barometric Pressure / Altitude / Temperature Sensors - Adafruit 2651, The Adafruit BMP280 I2C or SPI Barometric Pressure / Altitude / Temperature Sensors use the next generation BMP280 sensor with an improved accuracy of ±1 hPa. They use only 2 x GPIO pins and provide you with precision air pressure measurements. Each board contains a 3.3V regulator, an I2C level shifter and pull-up resistors on the I2C bus making it 5V ready. The boards also support SPI which is handy if you want to use several sensors on the same bus. You can set the pressure sampling rate up to 128 samples per second to obtain a good averaged result whilst it's probably sufficient to sample temperature once per second.Adafruit supply a tutorial and library to get you started. The library also provides a subroutine to calculate the altitude given the air pressure with a resolution of ±1m and a range of -500 to +9000m above sea-level. Though, if you're 500m below sea-level, you may want to use a different sensor. Supplied with a fully assembled and tested sensor board plus a strip of 0.1in. header pins for you to solder on as required.

| "Adafruit Bluefruit BLE Bluetooth Low Energy Boards - Adafruit 2633, The Adafruit Bluefruit Friend Bluetooth Low Energy Breakout Board lets you cut through the pile of Bluetooth Classic APIs, development tools and licences, and treat a Bluetooth LE connection just like a serial link. Send and receive keystrokes from your favourite terminal software, from software such as Python (via PySerial) or from your smartphone. Adafruit have built a software stack right into the Bluetooth LE board, so you can focus on sending and receiving the data you want for your application. Its optional command mode lets you create GATT services and characteristics, make it into a UriBeacon and set the device advertising. The UriBeacon is part of the Google ""Physical Web"" initiative where a Bluetooth LE device broadcasts a URI which smartphone and tablet apps can detect. For example, the URI could lead to an interactive page of sensor data. Another particularly useful feature is the over the air (OTA) programming from any BLE capable iOS or Android device.The Bluefruit Friend is based around the very capable MDBT40 chipset (similar to the Nordic nRF51822) with Adafruit's own 100% custom firmware. The MDBT40 has an ARM Cortex M0 core running at 16MHz, 256kbytes Flash memory, 32kbytes SRAM. It talks to the host microcontroller over 4 or 5 wire SPI.Supplied as a fully assembled and tested Bluetooth Low Energy board plus a strip of 0.1in. header pins for you to solder on as required. See Adafruit's ""Quick Start"" guide, part of their massive free tutorial with software examples. They also provide an Android app and an iOS app which can talk BLE to your project.

There's a small trimmer pot on each one to adjust the gain between 25x and 125x so that you can minimise volume related distortion. They can be supplied with 2.4 to 5V DC and are capable of rail to rail output with a DC bias of Vcc/2. Be careful when selecting your power supply, 5Vpp may offend the Line Input of a standard amplifier for example. If you want to connect one to a Line Input then use a blocking capacitor of between 1 and 100µF unless you have a differential amplifier or it already has its own blocking capacitor.Adafruit recommend using a low-noise 3.3V DC supply if you intend connecting these amplifiers to an analogue to digital converter (ADC). In this application there's no need for a blocking capacitor.Get started quickly using Adafruit's tutorial for this microphone amplifiers showing how to wire them up to headphones. Having mastered that, you can move on to connecting one to a microcontroller. Adafruit have a tutorial and FFT library for the Arduino which extracts frequency information from the audio and another which is a sound level tutorial.Supplied with a fully assembled amplifier board, and a strip of 0.1in. header pins for you to solder on if required.

| "Adafruit Standalone Capacitive Touch Sensor Breakout Momentary or Toggle - Adafruit 1375, The Adafruit Standalone Toggle Capacitive Touch Sensor Breakout boards operate without the need for a microcontroller using an AT42QT1012 sensor chip. They are of the touch-on, touch-off type. When a touch is sensed, an on-board LED will alternately turn on or off and the output pin will follow, high (logic 1) when the LED is on and low (logic 0) when the LED is off. You can save power by isolating the LED by cutting a trace on the board. It's OK, the trace was specifically placed for just this reason and if you change your mind a small blob of solder will re-enable the LED. Out of the box the switch will remain on until you turn it off, by the same trace cutting trick used for the LED, you can add an RC timing circuit to have it automatically switch off after a specific time. You can also use your own touch pad by connecting it to a solder pad on the board. These are neat little boards with some interesting customisation options. Supplied as an assembled board plus a strip of 0.1in. header pins for you to solder on as required.Please note that these are logic level switches and not power switches.

It's OK, the trace was specifically placed for just this reason and if you change your mind a small blob of solder will re-enable the LED. The chip is set to fast response mode which requires 0.5mA or you can set it to a slower mode that only uses 50µA by the same trace cutting trick used for the LED. You can also use your own touch pad by connecting it to a solder pad on the board. These are neat little boards with some interesting customisation options. Supplied as an assembled board plus a strip of 0.1in. header pins for you to solder on as required.Please note that these are logic level switches and not power switches.
