In this tutorial we are using an LCD Display and building a menu system which allows the user to scroll through different parameters. This system is commonly used on hardware devices such as VFDs, microwaves, etc.
We will be looking at the software which scrolls through 10 different items and allows the user to change that particular parameter for later use in their code.

I've been spending a while looking for videos to help me with programming and LCD menu on Arduino. This has been by far the most helpful! Thanks.

Super good. Integrating this into a temperature controller for bioethanol fuel cell research, controlled with a joystick. Changing parameters can be scaled by the y axis of the joystick, so the further away from the middle it is the faster the value changes.

about 20 years ago, I remember making a menu system from if statements, my problem was that they weren't mutually exclusive. Meaning, if you meth the criteria of one, you could then also meet the criteria of the next and next. So I eventually switched over to Case statements. This has it's own follies, but the system is much more exclusive. Thanks for the video. I'll keep pluggin'

Hello sir, awesome project by the way, I implemented the same and wanted to try out one feature, like I have another button which is pressed to execute something with respect to the values i recorded in the menu. eg. I put run time and frequency in the menu and stored the values in the variable and now i want to use these values and execute a basic command. like if there is another button which when pressed executes some codes taking values entered previously. how do we do it?

Very nice! Thanks for this.. the question is, I have 10 different functions (function one for example is 6 LEDs that blink in succession, two would use a Pot to adjust the blink rate, etc etc). They are set up in Switch/Case format using the Serial interface to choose items. How do I plug what I am trying to do into your menu system? This looks very promising! It would end the requirement of having to open the serial monitor.

Many thanks to EEEnthusiast for your introduction. Following your guidance, can I have 02 questions as following: 1. Link menu to an action such as show date/ temperature: I tried to deal with inserting a function like ShowDate but when running the showdate, button click is nolonger avaiable to change menu. 2. How to make a setup code so at first the LCD will print out date/temp or general information. After clicking a button, menu will so up and we can choose other action below. After finishing or time out the menu goes back to the general screen. Please be so kind to advice me.

It's a drive I see quite frequently in the field, but you're completely right in saying that it is an older model at this point. For most panels I specify nowadays, I've been using PF 525 drives. That being said, they have somewhat of a different screen setup, but it still applies to some extent.

Thank You! Great tutorial!!! Question: I used serial print to view the Variables. When the code starts it shows: (screens[currentScreen][0] shows Motor Voltage, Motor Voltage, Start Time, Motor Voltage Serial.print (parameters[currentScreen]); shows 1,0,0,0 Serial.print(screens[currentScreen][1]); Volts, Volts,Times,Volts so at startup it looks as if it is not setting all the button presses to 0 untill it goes through all the buttons. Is their a way to fix this? I attempted to debug but could not figure out why it was doing this. Thanks! Again.

Vlad is it possible to do something similar using capacitive or resistive touchscreens and instead of using momentary contact switches to change options, settings, or parameters simply touch the screen where the item one desires to modify and a drop-down list of options opens up? If so, this would be a great addition to this tutorial since small touchscreens with enough area to carry this out are cheap. By the way, the regularity of your posts is great and the production quality has improved too. I truly appreciate the time and effort you put into these videos as well as your willingness to freely share your knowledge and experience with the world. Thanks, brother you are truly a blessing! Peace!

Switching between these two menus was good but I noticed that the lcd display did not keep updating the voltage from the input pins. can you help me? thank

@Mtaalas 5 жыл бұрын

As long as people understand that this is beginner level stuff, this is a good tutorial. I mean there are no interrupts utilized, the menu structure and arrays could be saved directly to flash so you could save on RAM and there could be display buffer such that you render to that buffer and then when it's ready you send it to the LCD using hardware SPI/I2C module etc. etc. Debouncing could utilize hardware timers as well and buttons shouldn't be polled if not necessary but be interrupt driven (either timer or state change interrupt). It's a good tutorial for those who want to learn the basics regardless. :)

Thank you for explaining this, googled Arduino menu and glad I saw this. I do have 2 questions. How could we go about having that first screen be a sort of home screen.... specifically, I want to do this for time and temperature. The menu would be used to set low temp, high temp and then time on and time off. On the home screen I'd like to show actual temp and time. My second question is on time.... how would this be implemented to change 12 hour time, would you have a menu screen for each element (hour, min, am/pm) or is there a way to select only the section of time you want to adjust? If you show this in other videos, I'm going to go check out your others now, but could you let me know which one(s). Thank you.
