Arduino menu navigation with rotary encoder and LCD

[@gsuresh2u]

Hi, good wor on this Have you done any sub menu system for this board? I want to use STM32F411CEU6 board with sub menus Please reply, are you available on freelance?

[@CuriousScientist]

Hi! Yes, I even have a video about it, roughly from a month ago. The board I used in that project is an Arduino Nano, but as long as the project allows us to use the Arduino framework (STM32duino), it does not take too much to implement it on STM32. The main limitation is usually if there's any available library for the display. You can write me a mail and we can discuss the rest.

Complimenti.Bravissimo 👏👏👏👏

[@CuriousScientist]

Grazie!

[@daftar.wow_]

what software do you use for coding?

[@CuriousScientist]

In this video, it is the Arduino IDE. Otherwise, when I write more complex codes, I use MS Visual Studio with the VisualMicro plugin. It costs money, but it is a fair price.

[@daftar.wow_]

ok thanks, nice video🤜🤛

[@CuriousScientist]

Thanks!

[@jeffvenqueleir2036]

Nice explaine good teacher I am going use it in the futur with some extra"s

[@CuriousScientist]

Thank you! Glad to hear that the project was useful.

[@christophe8569]

I had to change lcd.begin(); by lcd.init(); but for the rest it's awesome. Thanks.

[@CuriousScientist]

Hi! I am glad it worked! I also noticed this behavior when begin() does not work but init() does or the other way around. Probably some confusion with the library versions.

[@kijijikhalid601]

great tutorial and and the explanation was much clearer. thank you

[@CuriousScientist]

Thanks!

[@ramilbraganza8103]

Thanks for this Arduino project I will used this to drive relay to switch on/off my lightning.Can you make video for this that we can set time/timer for individual LED to turn off?

[@CuriousScientist]

Hi! Sorry, but I don't make videos on requests, unless you want to sponsor me.

[@bgaworkshop7209]

Thanks for very precise explanation.

[@CuriousScientist]

You are welcome!

Hi, I want to control 6 Relays on 3,4,5,6,7 &8 pins, with rotary encoder . in the start OLED display text "rotate your encoder" when i rotate display changes to "RELAY 1", when I push the rotary push button arduino will switch on the D3, same way it goes forward and reverse also. ...please help.

[@CuriousScientist]

Hi! What is the issue?

[@Sizzlik]

The code on your website seems to be faulty. it should be lcd.init() instead of lcd.begin() in the setup().

[@CuriousScientist]

Hi! The code is working fine, and the best proof of it is the video itself. Keep in mind that there are multiple libraries out there for this specific LCD. You may be using a different one. Cheers!

Yeah, well, that's not the same that I used.

Thanks a lot.

Exactly what I was looking for, thanks for your effort in time and knowledge!

[@CuriousScientist]

I am glad that you found what you were looking for!

[@719gt4]

@@CuriousScientist me as well😉 I know some musicians and they still haven’t found what they looking for....🙊

[@CuriousScientist]

Show them my channel, haha. Maybe they also find it here.

[@PhiphiBelgium]

Nice video , many thanks ; but some remarques. Make you code saver , lighter and readable: You don't need to store the state of the i/o's . Only reverse the of them with "digitalWrite(x_output,!digitalRead(x_output);", and if you need to reed the state just 'digitalRead(x_output);' (expl : for LCD) Alsow you could store the i/o list into a array , and use index of the array as index for your switchcase.

[@CuriousScientist]

Hi and thanks! The code is freely available, so you have all the freedom to modify it to your requirements. You can also improve it. I am not a programmer, just a hobbyist, so as long as it works, I am happy with it. By the way, there is a more recent video on a similar issue where I applied a bit smarter principles: kzbin.info/www/bejne/Z2PRgIqrh6urb80

[@isidoromaich7226]

Cool stuff, the code was well explained

[@CuriousScientist]

Thanks! I have a Nokia 5110 display which has more lines. I am planning to make another video on this topic and show a bit more advanced stuff. The LEDs are spectacular but maybe not the best for demonstration.

[@edgaresn1]

how you can do the same with an tablet home screen menu any advice or help im trying no luck after a week trying

[@CuriousScientist]

I am sorry but I do not have any experience with tablets, I don't know.

If I want to use the encoder to select of many fixed numbers from an array such as float DoF[13]= {0.1, 0.5, 2,3,4,5,7,9,11,13,15,19,22}; do I need to make a case for each value?

[@CuriousScientist]

Depends on what you want. If you just print the element, you can call the ith element from the array. If there is a corresponding action, yes, you might need to do everything one by one. Your description is too short to know what you want exactly.

[@johnossi4234]

​ @Curious Scientist OK let me fill in the needed details. A stepper drives a linear track. A starting point (0) and ending point (say at 120mm) are previously defined by the user. Even though the stepper will begin at 0 and end at 120mm it must pause at uniform locations and fire an LED and report its new position each time. The user must select (from the array) the segment to be traveled between the firing of the LED, before the stepper can begin. So if the user selects "5" from the array, then the stepper begins by running to the start (0) fires the LED , moves to position 5mm, fires the LED, moves another 5mm to position 10mm and fires the LED and repeats till the end (120) is reached. The code works well when the user enters the sequence distance (5 mm in my example) through the serial (computer keyboard) but I want this choice to be made through the encoder displayed in the LCD so a PC will not be needed.

[@CuriousScientist]

This can be done with arrays. You can store everything in arrays and keep track of the indices, so you can refer to other related values located in other arrays.

[@SMV1972]

Отличный урок. Спасибо!

[@CuriousScientist]

You're welcome!

[@mohsenmehrabi298]

Great can we do the same with buttons

[@CuriousScientist]

Yes.

Thanks, I guess. 😅
