Mega 2560 and My Own Device Help

Hello friends, there is a device that works with Arduino mega. This device is a curve follower. It consists of a total of 12 LEDs and 12 buttons on the front panel, 6 of the buttons are used for different voltage options, 3 of them are used for frequency and the other 3 are used to select a/b channels and create a continuous loop between a/b channels. kind of like a flip-flop.

I want to add Autoscan mode to this device, it is necessary to add a button and an LED for this mode.
When you press the button, the mode becomes active, when you press it again, the mode becomes inactive. If the mode is active, the LED lights up continuously to show that the mode is active, and if the mode is inactive, the LED turns off. Also, when the mode is active, it should work as if the 6 buttons on the front panel were pressed sequentially, one second apart, that is, 1.2.3.. .. should press the button .

// the setup function runs once when you press reset or power the board

What you're looking for is a state change detection; there is an example in the IDE.

When the button becomes pressed while you're not in autoscan mode, you set a variable to indicate that you're in autoscan mode. When the button becomes pressed while you are in autoscan mode you clear that variable.

Based on that variabele you can execute either the normal code or the autoscan code.

It could press the buttons. This is known as hijacking, and there are a variety of techniques. Which will be possible and which one would be best depend on what you are hijacking.

Example: a normally open pushbutton.

Method: connect a set of normally open relay contacts in parallel with the pushbutton. To "press" the button the microprocessor commands the realy to enrgize.

Advantages: clearly it will work, simple, electrically safe usually

Disadvantages: lotsa relays. Slow, relatively. Will wear out one day too soon perhaps.

And so forth, alla way uo to getting very much in there to take a more direct control of things.

Ppl use transistors, optoisolators, solid state relays, CMOS switches in places where enough is known about the device being hijacked to allow doing.

The code for the process you outline is trivial. I suggest you write that code independent of hooking it up to anything real. Use push buttons and LEDs as proxies for what will be added in later phase to connect directly to the real device.

Do you benefit from being able to read and react to the exist buttons? Or is preserving the ability to continue using them as designed sufficient or can you say the pushbuttons will see of no interest once the Arduino is in there (which coukd actually live between the real existing push buttons and those points to which they were formerly connected)?

Snap a few pictures of the device and ,ink or post any documentation you have for it. Also carefully dream big at this early point about what and all the addition,of the Arduion coulddo for you. It is easier to dream big and do less than to add features you think of every time you get close to "finishing" a project.

Merhaba arduino kodum bu şekilde,ben bir buton daha ekleyip bu butona bir kez basılınca bir ledin sürekli yanmasını ve kod içerisindeki m1 den m6 ya kadar olan butonlara sırayla basılmış gibi çalışmasını istiyorum ve butona tekrar bastığımda bu döngü dursun istiyorum
