Hi, I’m also a newbie in programming. But I took my time and started reading and watching many tutorials. So I’m proud that I have completed most of my project on my own. What is my project? I have an old traffic light from a rail crossing. It has two lights. I want to control the lights with the…

[image] John115: I just ended up copying and pasting the code 10 times…. It's ugly but is it that bad? It's both ugly and bad.

[image] John115: Also and more important: What can I do to stop my “sequence”? So if I click the third button and my light sequence is starting to repeat for 10 times, how do I stop / cancel it? You have to use non-blocking logic using millis() instead of delay(): https://forum.arduino.cc/t/…

[image] John115: couldn’t get that method to work so I just ended up copying and pasting the code 10 times…. It's ugly but is it that bad? Technically, yes, it's not optimal, but if you're satisfied, who's to judge? For a learner, getting something done is better than walking away in disgus…

consider // possible model RR gate flasher enum { Off = HIGH, On = LOW }; byte pinsLed [] = { 10, 11, 12 }; byte pinsBut [] = { A1, A2, A3 }; #define N_BUT sizeof(pinsBut) byte butState [N_BUT]; // ----------------------------------------------------------------------------- int chkButtons ()…

I see the pragmatism at work here, but there is one specific danger to beginners in the multiple copy and duplicate approach - typographical errors. Because often, the duplication is not literal, instead some text string has to be edited to make some sequence, like digitalWrite(pin4, HIGH); delay(2…

Rather than just duplicating the code what you need is some kind of looping structure, like a while or for loop. while - Arduino Reference The Arduino programming language Reference, organized into Functions, Variable and Constant, and Structure keywords. …

[image] John115: I couldn’t get that method to work so I just ended up copying and pasting the code 10 times…. That is a perfect way to start. From running this you will either succeed or be introduced to errors. Little by little you will learn to correct the errors, then recognize errors bef…

Hello John115 Welcome to the best ever Arduino Forum. Take some time, study the IPO model and take a piece of paper plus a pencil and design a program structure. Identify modules could to be coded and tested separetly. Merge after sucessfull testing all modules together to the needed project. It…

Hi Josh, Your wanted functionality is medium advanced. This requires medium advanced knowledge about programming. repeating a part of the code multple times: using a for-loop or a while-loop making the code responsive all the time = beeing able to change from one sequence to something else at a…

Hi, thank you very much for all the replies. I'm starting to read into all the articles and tutorials you have mentioned. I also started playing around with libraries (for example Toggle, EButton, Cooperative Multitasking etc.). They have made my learning experience more fun and successful. I wi…
