Features

  • Uses the HC-SR04 Ultrasonic Sensor
  • Uses the VL53L0X Time-of-Flight Sensor

Benefits

  • Free, open lessons: the Learning MicroPython textbook has the kit page, wiring, and MicroPython code.
  • Real-world data: students read sensors and turn measurements into decisions.
  • Budget: about $17 (all three sensors: HC-SR04 about $1, VL53L0X about $2, IR about $1; OLED about $4.40; Pico $4, breadboard $2, wires $1, USB cable $2).
