Snapping is an introduction to the open source Arduino hardware-software coding environment embraced by the Maker community worldwide.Arduino is the most popular microcontroller used by Makers and Do-It-Yourselfers to MAKE and DO.Snap Circuits are easy to use and the large format component modules are easy to handle and make prototyping circuit designs a snap! - No Need for bread boarding since Snap Circuits snap together and Snapping shares the same functionality as all other Arduino compatible, boards, shields and components.- Snapping is backward compatible with Snap Circuits and can function with all of your current and future Snap Circuits sets.- 20 Snapping Sketches (programmes) already written for operating the 14 included parts.Additionally, you will find sketches written for Snapping and other kits so you can keep your Snap Circuit fun going.- Included: 1 Arduino UNO compatible Snapping Module - 6 Snap Circuit Modules - 3 Snap Wires - 1 Snap Jumper Wire - 1 Snap to Pin Wire - 1 USB Cable - 1 9 Volt Battery Holder - 1 Manual.- Ages 12 and up - 9 volt battery needed but not included.- You will need to download the Arduino application from Arduino's own website and you can download Snapping Sketches (programmes) from the Elenco website.
