Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. We’ve taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program.
The Kitronik Inventor’s Kit for the BBC micro:bit provides a fantastic way of learning how to construct electronic circuits and create code. The BBC micro:bit has a selection of pins that are located on the bottom edge of its PCB. By using Kitronik’s specially designed ‘edge’ connector board in conjunction with the breadboard, it is easy to use these pins to connect additional components. No soldering is required and the first circuit can be built in minutes! Huzzah!
This Finger Pulse Oximeter with Bluetooth LE is great for monitoring your blood oxygen levels and pulse rate. Simply slide your index finger pad onto the springy sensor and see the readout on the OLED display. You’ll see your heart rate pulse, blood oxygen estimation SpO2, and even a little graph of your blood pulsing.
If you’ve ever ordered and wire up a 9-DOF sensor, chances are you’ve also realized the challenge of turning the sensor data from an accelerometer, gyroscope, and magnetometer into actual “3D space orientation”! Orientation is a hard problem to solve. The sensor fusion algorithms (the secret sauce that blends accelerometer, magnetometer, and gyroscope data into stable three-axis orientation output) can be mind-numbingly difficult to get right and implement on low-cost real-time systems.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
