The Circuit Playground Express is the top choice for educators and parents because it has so much packed into it! Use it when you want sensors, buttons, and touchpads to trigger events like lights and sound. It also has an infrared (IR) transmitter and receiver that lets you create interactive games or turn it into a remote control.
