Hello, I've been trying to make this code work for the past 2 days. I will try to describe the idea as detailed as possible. I am making 4 way traffic light system, and I want to have two modes, automatic and manual. first mode: if I enter the numbers 1, 2, 3, or 4. the corresponding traffic lig…

Welcome to the forum [image] hakarmustafa: I tried using "delay" but I have to wait for the complete loop and then enter numbers in the serial. See Using millis() for timing. A beginners guide , Several things at the same time and the BlinkWithoutDelay example in the IDE

thank you. See Using millis() for timing. A beginners guide , Several things at the same time and the BlinkWithoutDelay example in the IDE I have looked into millis() before but I can't seem to figure out how to implement it in my code, as I have a lot of delays to replace. any clues?

[image] hakarmustafa: how to implement it in my code It probably won't be a matter of implementing it into your code. You can keep the ideas of how the timed elements should work, and your need to have the system be responsive, but the code will look very different to the point that beyond p…

[image] hakarmustafa: any clues? Hello hakarmustafa Yes. Take search engine of your choice and ask the WWW 'led sequencer +arduino'. Have a nice day and enjoy coding in C++.

[image] paulpaulson: Take serach engine of your choice Haha, I saw you typing and I thought I'd beat you to the punch on the IPO thing. :wink: a7

consider this sequencer with a "sequenced" override. need to wait for current green to sequence thru red before make selected light green // traffic light struct Sig { const byte PinGrn; const byte PinYel; const byte PinRed; int cond; }; Sig sig [] = {{ 2, 3, 4}, {5, 6, 7}, {8, …

It's not an exact analog of your problem but, maybe it'll help the visualization. [image] State machines, a short tutorial Tutorials A common response to “I want my code to do A., then B., then C., etc.,” from the knowledgeable is “Use a state machine.” Many w…

[image] gcjr: need to wait for current green to sequence thru red before make selected light green Unless the selected light is the current light. What's the button supposed to do? a7

[image] alto777: What's the button supposed to do? was a way for me to pause the timer

[image] alto777: Unless the selected light is the current light. was that a requirement ? :wink:
