The lessons teach you basics, like coding terms and thinking in code, as well as get you to create programs to do things like turn the Bolt into a Hot Potato game, display different images on its LED matrix or move around in different shapes. Sphero makes multiple-lesson tutorials, accessible online or through the app, to introduce users to each form of writing code.

To program Sphero, you need to write code in the Sphero Edu app, either through drawing, block coding or writing JavaScript. However, you can program the Bolt to drop stabilization. In fact, even with the Bolt off, it will automatically spin to this orientation, no matter what way you place it down. The Bolt spins inside itself to stay balanced, keeping its light matrix on top and ballast weight on the bottom. It handles movement with two encoders (tracking movement and distance) and two motors. To stay balanced, the Bolt uses an IMU (inertial measurement unit), which reads the accelerometer (measures acceleration), gyroscope (rotation speed). There’s also a magnetometer for finding North and auto-aiming the Bolt so that it’s tail light is facing you, which is required to run any program. These messages can fulfill a conditional and execute a certain portion of a written program. Sphero has four infrared red emitter and receiver pairs, which can be used to send and receive messages to another Bolt. It’s plenty bright, especially with that clear shell holding nothing back. Each of those lights can hit a brightness of 200 lumens, which is approximately 33% that of a 60-watt lightbulb. All of these lights are programmable, and the blue one is used to aim Sphero so you know what direction it’s facing. Outside of the 8x8 RGB LED matrix sitting at the top center of the Bolt, it has two RGB LED lights, plus one backlight that can only be blue.
