Bluetooth LE (BLE) is a common way for mobile devices to connect to accessories, watches, and toys. Getting that same connectivity on the desktop has been really challenging – every platform does it differently and its still not very stable. Luckily, there’s now a cross-platform way to connect to BLE devices on any computer – Web Bluetooth lets you connect to BLE devices, right from your browser!
In this guide we’ll show how you can test BLE devices from Adafruit in the browser, streaming in sensor data, even controlling LEDs and buzzers using the Adafruit Bluefruit Dashboard page.
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.
