LEGO WE DO 2.0 Lego WeDo is an educational and interactive robotic system, and programme. It does what you please How? Download the app on an i pad and soft wear on a laptop. You start with the glowing snail. Then a step by step programme comes up on the screen. What does it do though? Move, change colour, and sound. WOW, what age do I have to be to do it? 7+ Which set should I get first? The core set is the best for starters, and make sure you have 2 AA batteries. Thanks a lot. WARNING LEGO wedo is very expensive but definitely worth it.
