    Hi midhun, i feel sorry to reply late to a past message, but weirdly i didn't seen appeared on the instructable page but in my Gmail mail box, something i seldome check i admit :) .. Anyway, thank you for ur answer and ur explains. I understood well about why the "255" in backward way ;) it was evident for sure.Since last message i worked on it, and honnestly it works reallllly not bad. I finaly found the best settings for the walue of Kp, Ki and Kp. and now i can drive it better with the tablette. I will do a little video next day i will send you on Gmail ;) next step, adding some sound :) I have had put again the big wheel, and thats better than with the small one. About RemoteXY, for sure u should have a look on it ! I'm sure you will find a good used to this app

  • How to - E-INK E-PAPER DISPLAY MODULE – Part 1

    Hello, I notice this post has already one year old, but i have a question. U know there are in most of shop such screen to display prices, do you think it is possible to take one, and "modify" it, for using in the way you show and explain ? Thanks in adavanceSerge

    Arduino Self-Balancing Robot

    Hi, u surely right because i didn't noticed any changment, declared or not. I still working on it, it is running... not badly. But, i still have some problems. The biggest is when suddenly the robot start to run (forward of backward), it seems on constant angle, speed increase, then finaly unable to compensate it falls down.I tried to write some lines comparing speed, angle, acceleration, but not succed :((( if U have some ideas, i will be happy to have your help. thank you in advance

    Arduino Self-Balancing Robot

    hello, :) I have an other little question, it is about the interrupt pin. I'm using a arduino micro for my own and because it is not exactly the same than urs pro mini, i have to use an other interrupt pin than 2 the "original" pin. I declared it in my sketch, for sure, but should i modify something else in the skecth to be sure it is rightly used ? Thank again Wish u a nice day

    Thank you for ur advise and ur replys :) At first i have change the wheel with smaller one, i noticed it is better for it stabilty. Anyway for now it does the same thing and sometime, when it has found equilibrium, his constant speed increase, look like a larsen, then finaly fall down on forwarding, more than backwarding. There is a "weird" added in ur line, you add 255 to the motor control when motorspeed is < 0 .. but 255 is the limite of power ! so why do u add, i tried to delete and seems it is not changing anything.i will follow ur method and will set kp at first,honnestly thats what did already :). I already change the filter time constant and i notice it is better a few when i increase it. around 0.08to control it and move forward or Backward, i modify the targetAngl...

Have same nice dayBest regards from France PS: for controling with tablette i'm using RemoteXY it is really a great soft ! do u know it ?

    Hi midhun, i worked on it this weekend so i can do some return already.About the stability i think i will not do better :) Thats really not bad on any ground. But the capability to keep awake thats an other problem :( I noticed that when the robot start to run with a stable speed... it "lost control" then finaly fall donw.i don't know how may i control the "increase speed" and be and it standing up. if u have some good idea i will like listen to u and follow ur advise.Thank you in advance.PS maybe motor encoder will be the only solution to be able to control the moving.

    Arduino Self-Balancing Robot

    Hi midhun, I made it... it is a bite taller than Urs, but i used ur informations and ur sketchI added bluetooth to be able to control and do some setting on a second page. It is RemoteXY app. Thats great ! I added too too 3 colours led fixed under the sonic sensor, it light inside through a little hole i did :) It runs well, but still have some "little" problems. On a carpet it is 90% perfect. On floor tile it is too much reactive, do yaws, runs too fast and finaly falls down . I try to modify the Kp, Ki, Kd... but it seems it is not the efficient way to act.May U suggest me how to deal with ? Thank you in advance and have a nice day

  • Remote Monitor Arduino with iPhone via 3G/4G/Wifi

    HI,I'm Really interrested in ur iphone application and i installed it already. In fact i have a Recently bought a Arduino Mega card with a ES8266 shild made on " https://fr.aliexpress.com/item/Mega-WiFi-R3-ATmeg... "and i would like be able to use directly on WIFI with ur application.My "little" problem is ur ino are writen to work with ethernet. I'm not that good to be able to do the modification directly. I will like u can help me to do. This kind of boards is new and it is not easy to find exemple or help online.I just know how to communicate and check the two boards, on AT commands. Thank you a lot in advance.SergePS If u are ok we can exchange Mail Adress
