Picocricket is aimed at primary schools, age 8 and up. From the same people who created Scratch. Combining Art & Robotics to spark Creative Thinking. Not free.
A PicoCricket is a tiny computer that can make things spin, light up, and play music.
You can plug lights, motors, sensors, and other devices into a PicoCricket, then program them to react, interact, and communicate.
I am a secondary teacher in New South Wales, Australia where I teach computing courses from Years 7 - 12. I am mostly a full time classroom teacher with a small time allowance for integrating eLearning within the school.
