Teacher's Instruction
  1. Allow students to pick any one mini project based on their interest.
  2. Introduce the mini project and explain the objective of each activity.
  3. Guide students to open and follow the instructions provided for each mini project.
  4. Encourage students to identify the sensor input, controller logic, and output action in each project.
  5. Allow students to test and modify their projects using CircuitPython.
  6. Guide students to troubleshoot connection and programming errors.
  7. Encourage students to explain how their project works after completing the activity.
