DescriptionOur kit contains the Espruino Javascript Interpreter pre-installed which makes for the easiest microcontroller device to get started with. Espruino WiFi provides an easy, well-supported way to get on the Internet In addition to each Espruino microcontroller kit, are web accessible PC based software tools including the Web IDE (Web Integrated Development Environment), command-line tools, documentation, tutorials, and modules which form a complete solution to practice and learn. Also, the KitsBitsnBytes Basic I/O Sampler contains basic starter components that may be connected to the microcontroller to check out basic I/O (Input-Output) functionality such as detecting a button press and visually indicating an On-Off state via colored LED's (Light Emitting Diodes).
