| "Adafruit 1757 LED Sequins for Wearables Royal Blue - Pack of 5" |
| "Adafruit LED Sequins for Wearables - Pack of 5 - Adafruit 1757, The Adafruit Wearable Royal Blue LED Sequins can hook to your Gemma or Flora board to show off your coding and your design skills at the same time. Use PWM to make them fade or sparkle for your next wearable or cosplay project. They consist of a 1206 size LED with a 100 Ohm limiting resistor and only draw 5mA at 3.3V letting you stack 4 or 5 of them on a single GPIO pin. You don't strictly need an MCU either, simply power them from a LiPo or coin battery.Alternatively, if you like to control the colour of your wearable bling, take a look at the FLORA Wearable NeoPixels (73-5354) which are also available in a sheet of 20 (73-5369).

| "Adafruit 1777 SI1145 Digital UV Index / IR / Visible Light Sensor I2C" |
| "Adafruit Digital Infra-red / Visible Light Sensors with I2C, 5V ready - Adafruit 1777, The Adafruit SI1145 I2C Digital UV Index / IR / Visible Light Sensors use individual visible and infra-red (IR) sensors and calculate the UV index accordingly. They are 3 to 5V compatible and communicate with almost any microcontroller over I2C. Should you need proximity measurements, you can add an IR LED to one of these sensor boards for a detection range between 10 and 500mm. Adafruit supply a free tutorial and library to get you started with an Arduino, but the information should be applicable to most microcontrollers. Supplied as a fully assembled and tested board plus a strip of 01.in. header pins for you to solder on as required. Adafruit 1777 SI1145 Digital UV Index / IR / Visible Light Sensor I2C"

| "Adafruit 1384 GA1A12S202 Log-Scale Analog Light Sensor" |
| "Adafruit Analogue Light Sensor Breakouts - Adafruit 1384, The Adafruit GA1A1S202 Log-Scale Analogue Light Sensor is very simple sensor to use, just add power and then monitor the analogue output. Most light sensors have a linear response to the light intensity which means that they can be quite insensitive to low light levels and then max-out at high light levels. This sensor on the other hand has a logarithmic response which means that it is more sensitive in low light conditions when small changes in intensity make a big difference to a human eye. It's also less sensitive to changes in very bright conditions when it takes a bigger change to register with the human eye.The light sensor has a dynamic range of between 3 and 55,000 lux. 3 lux is equivalent to civil twilight. Here's a fun fact, evening twilight ends when the centre of the sun is 6° below the horizon. 55,000 lux is equivalent to full sunlight on a clear day.Supplied as a fully assembled and tested light sensor board plus a strip of 0.1in. pitch header pins for you to solder on as required. Adafruit provide a free tutorial to help get you started. When you read the datasheet you will see from table 3.3 that the GA1A1S202 provides an output current not a voltage. Adafruit have added a 68kΩ resistor to translate this to a more convenient and microcontroller friendly voltage of 0.3 to 3V. Adafruit 1384 GA1A12S202 Log-Scale Analog Light Sensor"

| "Adafruit AD8495 Analogue Output K-Type Thermocouple Amplifier Breakout - Adafruit 1778, The Adafruit K-Type Thermocouple Amplifier offers a quick and easy way of hooking up a thermocouple to your next project. Thermocouples need a cold-compensation reference and a good amplifier which is where the AD8495 chip comes in. It handles all the electrical complications and presents you with a single analogue output which you can feed into your microcontroller or other circuitry if you are going old school. In fact, this amplifier is so simple that Adafruit have silk-screened everything you need to know on the back of the board, including the formula for calculating the temperature.Supplied as a fully assembled and tested thermocouple amplifier board plus a strip of 0.1in header pins and a 2-way screw terminal block for you to solder on as required. Adafruit only recommend this amplifier for K-type thermocouples although the datasheet mentions J-type. Feel free to experiment, but we only support its use with K-type thermocouples. We supply the thermocouples separately. Adafruit 1778 Analog Output K-Type Thermocouple Amplifier - AD8495 Breakout"

There's an interrupt pin which goes active when data is available plus a 32-sample FIFO which lets the sensor record samples automatically for later download. The chips perform the altitude calculation for you which is handy if you roll your own software or are tight on code space. Adafruit supply a library and example code to get you started.

Containing two sensors, a full spectrum sensor which includes the human visible and infra-red wavelengths, and an infra-red sensor, the boards allow you to calculate the illuminance in Lux. This is handy for controlling LCD brightness according to ambient conditions or controlling exposure in photographic applications. They have a fixed I2C address so you can only have 1 x sensor attached to your microcontroller. They have 3.3V regulators and level shifters making them 3 to 5V compatible. Ideal for low power or battery powered applications, they have a very low current draw, only 0.4mA when actively sensing and 5µA in sleep mode.Supplied as a fully assembled and tested board plus a strip of 01.in. header pins for you to solder on as required.
