Very easy to follow. I am getting to an older age and trying to learn this stuff from zero knowledge has been difficult. I have had an uno and a riorand 6-60v esc and a fly sky remote control for going on 3 weeks with no progress. My goal is to build a go kart size remote control car with hoverboard motors. My grandson thinks I can build/make anything but fabricating from go karts to military ships is easy. Figuring this stuff out is just a different world to me. I hope you post more tutorials
Excellent video! I used your filtering algorithm (TrustFactor) in an Arduino balancing sketch to dampen the pid output to the escs controlling 2 brushless motors. It stopped the jittering completely and makes the motors run very smoothly, however the tradeoff is responsiveness to change requiring typically higher PID values to reach steady state but it does so nicely. Thanks and keep up the great presentations.
i have viewed all 9 tutorials, your explanation, documentation were simply fantastic, the best ones are those from tutorial 7 to 9, zwei wichtige Punkte: a) stepper motor , if you apply what you already know to servo, servo is actually quite amazing, as i did, stepper motors' size and cost comparing to servos like rds3135... b) you have enough kennis to build either a biped and/or a 4 limb robot, however, that is entirely your choice i hope what i have wrote did not offend you, if i did, my apology alles gute !!! bravo bravo !!! toll!!! toll !!! toll !!!
Thank you, this really means a lot! Im not sure if i understand your points correctly. In a) you said a servo might have been a better choice than a stepper? If yes then you are absolutely right, a servo would be a better choice in this project at this stage. The reason why i chose a stepper is because this way i can show you how to make a reasonably simple and useful class in arduino. In b) you asked if i can build a biped or a 4 limb robot? Actually i plan on making a 2 wheel balancing robot and then a 6 degree of freedom robot arm, also i will document those builds in a video series format too. Again thanks for your comment and your feedback! Let me know if you have any questions. 🙂
der frage ist nicht wenn..sondern... TAKE YOUR TIME AND PLAN IT OUT ... i have...and i am in the process to finish my prototype, 3d prints usw usw some has stated that pulseIn cannot be used concurrently, YOU HAVE PROVED THEM THAT THEY ARE WRONG...bravo bravo bravo !!!, next, i am using newping, and one can build a class with it also to ping multiple us-015( a better quality than hc-sr04) AS A CLASS CONCURRENTLY, AND THEN A PIR...the problem is now how to attach them to a mega2560...i will figure that out...in time... Gott weise wenn hahahaha
very neat project. i have seen some roject with ultrasonic sensor but this is the first time with a 4 ultra sonic sensor. i think its a brilliant idea. if you don't have enough quality in ultrasonic sensor, you can still reach the desired succes with required quantity. subscribed.

Thank you! I'm glad it helped you out.
8:37 That's what I was looking for. Thanks!
Great explanation of an exponential filter.
Can it be used to smoothen water tank level's fluctuations

weighted moving average exponential ... cool video

Hi NHG, thanks for the in-depth video!
Is this "Trust Factor" calculation better than e.g. using the "Median"?
Very informative ❤️
Where will I find the the data?
where does the measurements.txt gets storaged?
It's been a while, but if I remember correctly it should be saved in the same folder where your processing script is.
where is the tutorial 10 ?
einfach toll toll toll
