Your experiences with micro:bit + TI calculators?

[Chhaya, Harshal S.]

 

Good morning,

 

Have you used micro:bit with TI-Nspire CX II or TI-84 Plus CE Python in your classes or your camps/clubs?

 

Could you share which activities you have done? And in which classes?

 

Any feedback or suggestions for the hardware and software and activities around micro:bit?

 

Thanks,

- Harshal

Hey Harshal,

My somewhat limited experience using the BBC micro:bit with the TI-Nspire CX II was with my one STEM Lab class. We started out with the 10-min-of-Code activities. One thing the students really got into was displaying messages across the micro:bits, like running display board. Another 
one that worked well was the "light sensor" project. I had the students work in pairs (limited number of micro:bits) and just walk all around classroom, hallways, outdoors, etc to measure and record varying light intensities.

Moving on to the Tello drone, the biggest problem was the limited number of drones (two) I had access to. Once a group had their Python codes ready to test their flight patterns, it was hard to get them to give it up and share........ and I only had around 12 students in that class :-)

Hi Harshal,

I can second Karlheinz comments, when it comes to interactive exercises among students, using the bluetooth radio of the micro:bit. Setting up basic communication is just a few lines of Python code and all the rest is creativity and fun, fueled by the students. The cybersecurity class has been successfully done with good participation at the Spring EMEA T3 meeting in Berlin, where you have been part of ;-). We refreshed interest just a couple days ago by running an online seminar, with good traction of 20+ people dialing in.

Bottom line, TI calculators offer a great mobile/portable user interface (UI) to the micro:bit, may it be as a text input device or a data post-processing/graphical display.

 

Best,

Hi folks,

Another great activity is building a metal detector using the compass that is built-into the Micro:bit.

I will share a sample program when I am at my computer later.

Using this activity with students new to coding, I run the activity in these “thin-slices” (Peter Liljedahl’s BTC lingo:)

1. Take one reading and display on Napire screen

2. Take a reading every second and display using the classic “while get key” indefinite loop

3. Store those periodic readings and time values in Python lists then bump them over to Nspire lists when done so they can be graphed

4. Add some threshold control that display something or makes a sound with the speaker when the reading exceeds the threshold value

5. Make it accessible to the visually impaired by using the compass reading (micro Teslas) to inform and play some sound frequency that is audible on the Micro:bit speaker
