Using these as cross-curricula sensor units requires adding a display, a keypad, SD module to save data. But what if you could build something greater than the sum of the parts? And cheaper? Greatly extend the capabilities of a calculator many students already own. You can even upcycle old Casio FX-9750 G Plus calculators - and transform both the Microbit and Casio calculator into a general purpose tool for physical education, health, science, mathematics, Internet-of-things (IoT), and robotics / instrumentation. Reduce electronic waste at the same time! What is that port for again? The forgotten feature in the 2.5 mm port of a Casio FX-9750 and FX-9860 is now available on my GitHub, open-source and free. It takes the burden off the teacher, because the learners become the experts - constructing, coding and repairing their own smart data logger that also acts as a remote control and automation control interface. This is an extension of my 2008 research, which carried classroom validation and student feedback, now with a modern facelift and cross-platform compatibility. Full serial communication between the Casio and Microbit Full bidirectional communication using the Casio serial protocol works with Arduino, Picaxe, Microbit, ESP8266, and ESP32. Learners can record heart rate, temperature, sound level, and other readings using sensors they build themselves, for cents or a few dollars. Use an old Casio G Plus (I got one very a few dollars from a second-hand shop) to give a alphanumeric display and a keypad to the Microbit. There low-cost universal serial interface is simple and connects with 5V and 3V microcontroller and Casio models safely. Instructions, C++ code, teacher and student manual are here: https://mikefentonnz.github.io/projects/casio-calculator-data-logger-hack.html So, what do you want to build using a keypad and display most students already have access to at senior level? A historical heart rate monitor? A NASA Mars orbital surveyor simulator? A colorimeter to monitor a chemical change that logs every 2 seconds or every 2 minutes? A remote control for a robot? A PIN pad to open a secure system? All these ideas are demonstrated and work - and the calculator still does maths!tutorialmakerspacestemteaching programmingmicrobit v1microbit v2microbit projectsdiyfitnessbbc microbitcodebig ideassensorlesson planshttps://community.element14.com/learn/learning-center/stem-academy/microbit/f/forum/54910/help-me-my-tobbie-ii-goes-zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz/223140Fri, 09 Aug 2024 06:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e9867f25-470e-40a4-b246-8835eb529905JWxor - if gears are not moving at all (and the motor generates this sound when stalled and unable to move the robot - similar to the situation when you prevent electric motor from rotating) it can indicate some mechanical problem resulting in the blockade that the motor cannot overcome.

If damaged gear can be identified, maybe it can be replaced or returned to the proper position?https://community.element14.com/learn/learning-center/stem-academy/microbit/f/forum/54910/help-me-my-tobbie-ii-goes-zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzThu, 08 Aug 2024 06:13:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:038d3424-980e-408e-8a64-829b89cec116swithinGuys my Tobbie-II is not working. when it was moving forward it goes zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz zzzzzzzzzzzzz.micro bithttps://community.element14.com/learn/learning-center/stem-academy/microbit/microbit-tutorial-videos/b/blog/posts/natasha-s-neopixel-led-bikeMon, 17 Jun 2024 18:10:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f7691acd-bcb7-48f1-94a7-41cbd32f8e26TechnoChicWelcome back! Natasha here. :) This is the 10th of 10 blog posts featuring each video in my series on animating LEDs with micro:bit and Make Code. If you've just stumbled upon this post, start from the beginning here. Watch the FULL Story of Natasha's NeoPixel Bike: This video tells the whole story of how I built my LED bike - the idea, the prototypes, the animations, the setbacks, the code, the - everything. www.youtube.com/watch I started with 30 pixel-per-meter NeoPixel strips on the frame of my bike that were controlled by Arduino. Then, I switched the whole project to micro:bit to utilize the onboard radio and sync the LED animations across the frame, wheels, and helmet. I tell the whole story of my journey - from connecting the pixels to trying out music-reactive animations - to maxing out the capabilities of MakeCode with some pretty advanced code - all made from blocks! Along the way I share tips for addressing NeoPixels, weatherproofing the project, and designing a user interface that’s easy to understand and use while riding. This video summarizes almost 4 years of work — and I have much more to do! I plan to keep going with this project so please stay tuned for more. Please subscribe to my YouTube channel (Subscribers make me so happy!) and join Discord to share your questions and ideas. Natasha's NeoPixel Bike Pics: {gallery}Natasha's NeoPixel Bike NeoPixel Bike Process: {gallery}Making the NeoPixel Bike What's Next for Natasha's LED Bike? Next, I’d like to create a NeoPixel jacket or cape and maybe some more accessories too! And, I want to improve on the controller, potentially adding a button matrix to make a more robust interface for changing animations. And, I want to explore more interactive animations that better utilize the radio and make the bike into a true VU meter that reacts to music! What else should I consider adding?
