Plan & Log - Session 3, 24w10, LP2408

24w10 Learn by Data Logging, and Fun Making with Ultrasonic Sensor 

• Recap: Boolean Logic operations (or, xor, and, not)

• Recap: KB013: DC Motor

• New knowledge input: KB016: Ultrasonic Sensor, and IR light sensor for line following

• Programmable vehicle experiences: 

  • PJ009.2: Collect MOVE vehicle sensors data

  • PJ009.3: Help MOVE vehicle finding a way out 

• Very fun learning with the ultrasonic and IR sensors data collection, we visualize the data and feel the perception sensing

• Very fun project with the PJ009.3: Help MOVE vehicle finding a way out 

• The agenda was majorly updated 1 day before the session, because the original plan with straight line driving calibration seemed not working well, and it's almost impossible to make a right-angle turning.

• This kind of hardware and real environmental situation dependent projects need to be very carefully planned and verified before the session, it's very risky to have the ideal plan not working in reality

• 89 Kr: Tutor parking

• 70 Kr: AAA batteries from ICA to supply the vehicle, these kind of consuming materials need to be shared by us together. But we don't share cost for other long lasting materials like Micro:bit board and the MOVE vehicle, they are provided for free.

• 39.90 + 18.9 Kr: Snack and drinking for fika 

• 10:00-10:13: 

  • Recap of KB012: Boolean Logic: AND, OR, XOR, NOT and KB013: DC Motor 

• 10:13-11:08: 

  • Knowledge input for KB016: Ultrasonic Sensor and IR light sensor

  • PJ009.2: Collect MOVE vehicle sensors data: Finished the measurement of ultrasonic sensor data

    • Use a box to measure short/mid/long distance: things worked well as expected, the measurement looked accurate enough

    • Use a marker pen as random small object to measure: it looked tricky, but if placing well in the range, it can detect the object as a result of a not so accurate distance value

    • Skipped using mug

• 11:08-11:20: 

  • Fika break

• 11:20-12:05: 

  • PJ009.2: Collect MOVE vehicle sensors data: Finished measurement of IR light sensor

    • On white and black paper

    • collected data analysis together

  • PJ009.3: Help MOVE vehicle finding a way out: A quick project, fun result as expected
