Snap Circuits Snapino - Snapino is an introduction to the open-source Arduino hardware-software coding environment. Learn to code and utilize your Snap Circuits modules at the same time! Fully-compatible Arduino UNO board with all normal features and is compatible with other Arduino shield and components. Snapino can be used with other Snap Circuitssets to make larger circuits Includes 20 projects that gradually introduce you to Arduino coding with sketches (programs) already written for operating the 14 included parts. Additionally, you will find sketches written for Snapino with other Snap Circuits sets so you can keep your fun going. Includes: 1 Arduino UNO compatible Snapino 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 - 9-volt battery needed but not included. You will need to download the Arduino application from Arduino's website and download Snapino Sketches (programs) from the Elenco website.
