Grove LED Bar is comprised of a 10 segment LED gauge bar and an MY9221 LED controlling chip. It can be used as a indicator for remaining battery life, voltage, water level, music volume or other values that require a gradient display. There are 10 LED bars in the LED bar graph: one red, one yellow, one light green, and the rest green. Demo code is available to get you up and running quickly. It lights up the LEDs sequentially from red to green, so the entire bar graph is lit up in the end. Want to go further? Go ahead and code your own effect! Features Each LED segment can be controlled individually via code Grove module Plug-and-play Can be cascaded for a larger display Flexible power option, supports 3-5.5 DC Available demo code Dimensions: 40 x 20 x 18 mm Included 1x Grove LED Bar v2.0 1x Grove Cable Downloads Grove LED Bar Eagle File Grove LED Bar Library MY9221 Datasheet Suli-compatible Library GitHub repository for LED Bar 10 Segment LED Gauge Bar

Circuit Playground Bluefruit is the third board in the Circuit Playground series, another step towards a perfect introduction to electronics and programming. Adafruit has taken the popular Circuit Playground Express and made it even better! Now the main chip is an nRF52840 microcontroller which is not only more powerful, but also comes with Bluetooth Low Energy support for wireless connectivity. The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Circuit Playground Bluefruit has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go! Features 1x nRF52840 Cortex M4 processor with Bluetooth Low Energy support 10x mini NeoPixels, each one can display any color 1x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection) 1x Temperature sensor (thermistor) 1x Light sensor (phototransistor). Can also act as a color sensor and pulse sensor. 1x Sound sensor (MEMS microphone) 1x Mini speaker with class D amplifier (7.5 mm magnetic speaker/buzzer) 2x Push buttons, labeled A and B 1x Slide switch 8x alligator-clip friendly input/output pins Includes I²C, UART, 6 pins that can do analog inputs, multiple PWM outputs Green 'ON' LED so you know its powered Red '#13' LED for basic blinking Reset button 2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.
