- Lab / 02Sensor experimentMPU6050 orientationSix axes of motion, turned into an angle you can see.
- Lab / 03Sensor experimentMPU9250 headingThe MPU6050's big sibling: nine axes, and a compass.
- Lab / 04Distance experimentUltrasonic rangingPing. Listen. Do the maths on the echo.
- Lab / 05Distance experimentLaser time-of-flightThe same question as sonar, answered with light.
- Lab / 06Detection experimentIR detectionIs something there? Is the line still under me?
- Lab / 07MicrocontrollerESP32The default brain for anything that needs to talk.
- Lab / 08MicrocontrollerRaspberry Pi PicoCheap, fast, and very good at precise timing.
- Lab / 09MicrocontrollerArduinoThe fastest route from idea to blinking LED.
- Lab / 10Output experimentLEDs & buzzerThe cheapest user interface there is — and the loudest.
