This product is replaced by a new version: Grove - Starter Kit V3.Grove - Starter Kit V3 As an open source hardware facilitator, we dedicate to make electronic prototyping easy and fast. We believe more effort should be put on concepts design rather than how to build basic circuits especially in the idea phase. Grove is a modular electronic platform for quick prototyping. Every module has one function, such as touch sensing, creating audio effect and so on. Just plug the modules you need to the base shield, then you are ready to test your idea buds. This Grove Starter Kit Plus is a upgraded version of our Grove Starter Kit. We included more frequently encountered modules in this kit to support your concept buildup. Meanwhile, we totally refreshed the whole image of this kit with eye-catching green and user-friendly booklet and stickers. If you were ever held back by the serious face of electronic modules, then it's time to review the point and discover the new face of it.Part List:Grove - Base ShieldGrove - BuzzerGrove - Sound SensorGrove - Rotary Angle Sensor (P)Grove - Touch SensorGrove - Light Sensor (P)Grove - VibratorGrove - Temperature SensorGrove - RelayGrove - Magnetic switchGrove - Switch(P)Grove - Red LED (3mm)Grove - Green LED (3mm)Grove - Blue LED (5mm)Grove - ServoGrove - Button(P) Grove - 5cm w/o buckle Cable x5 Grove - 20cm w/o buckle Cable x5 Grove - 50cm w/o buckle Cable x5 9V Battery Clip Grove Guide Book Sticker For all Grove users (especially beginners), we provide you guidance PDF documents.
