Taking Arduino skills to the next level:
These are gifts for intermediate and advanced users to build projects and have fun.
Robots are a great way to explore Arduino capabilities and show off skills. These kits are based on the robots that I built to demonstrate Arduino capabilities at Maker Faire. There’s a 2WD model ($169.99) and a 4WD version ($194.99) for running over rough ground. Or you can just buy the book, Make an Arduino Powered Robot, $24.99, if you want to build one from scratch.
