Raspberry Pi Pico W LESSON 57: Calibrating a Joystick in MicroPython

[@larryplatzek9017]

THIS IS ANOTHER GREAT LESSON, THANK YOU PAUL!

[@edSabio572]

Thanks Paul! You take math to a new level of usefulness...Ready to use/deploy. I am healed and back to your lessons.

Great lesson and love the math. Would like to see an explanation of what the magnitude formula is all about and how the formula was derived. Showing this on your pad like you do with the slope calculations, etc. would be very helpfull. You went over this very quickly.

I believe it is an application of the Pythagorean theorem. If you draw a straight line from any coordinate back to the origin, you can create a right triangle where the base (adjacent side) is your x coordinate, the height (opposite side) is your y coordinate, and the long side (hypotenuse) is the distance or magnitude of the point from the origin. You can then simplify A^2 + B^2 = C^2 to find that C = sqrt(A^2 + B^2)

👍thank you for everything you do. 🍻

Hi Paul, will there be anymore fusion 360 classes coming up please? Thank you 😊

I am legend! For fun, I put a low pass filter in as well.

LEGEND!

Hi there. The pico pi supposed to have a 12bit ADC instead of 16bit ADC. can you possibly elaborate in this statement, as scaling is going to be a bit different when using an OLED for example?

[@harshvardhan4771]

Lets talk in form of Spherical Coordinates (just because I don't have to define anything, not like I am drawing some analogy here). So, when you say that we have to calculate the angle, do you mean just the θ, or also the ϕ? Because the joystick sitting right at the dead-center, vs it being at the end of the +ve x-axis (equivalent of 0° in the 0°-360° anti-clockwise direction) couldn't possibly mean the same. We have to differentiate it somehow. And hence, we need the angle with respect to x-axis, as well as with the z-axis.

Here is my solution to lesson 56. I also added a wire and code to check for the switch in the joystick. kzbin.infoYT_F6okHYMQ?feature=share

Here is my attempt at it: kzbin.info/www/bejne/rYDLaZyOecyXna8. Thanks for the lesson Paul!

My HWkzbin.info/www/bejne/sGGcnZqJbL2ngJI. Sorry posted late. I did it almost immediately but did't get it on KZbin. Really! Honest I did!
