Brand new here and awaiting delivery of my Arduino and trying to get my head around a project I am trying to do.
I need to create a traffic light system, that when the red light displays, a barrier controlled by a servo is dropped to stop cars from moving.
Apologies in advance if my language on the coding side of things is off. Not looking for the code to be written for me just guidance on which direction to look otherwise I will never learn!
Am I right in thinking that I would create an IF statement. IF red light then servo does this ? Or is there an easier way to get the servo to move with the red light.
Start a little earlier... why is the light red, what event or action made it red, and how will you determine it is red (or on, regardless of color). Next is, what to do when these things have occurred.
You would not be the first one with this problem, so google is def your friend here
Try
arduino traffic lights
and see what I mean.
Give N plausible looking sites N minutes each. Read the specifications they are working to, and read read read the code they use to accomplish that.
N depends on too many things. Five to ten might be a start, in other words 0.5 to 1.5 hours of doing nothing but poking around with the goal to see what the possibilities are.
Keep it simple and stupid firstly.
Follow the example code that comes with the libraries to be found in the IDE or
run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.
You can have a blast using this project to learn…
It’s also possible you’ll try to run before you can walk !
Just step into it easy. The basic traffic lights aren’t too hard, but depending on your imagination, and the complexity of the layout, you’ll get in deep - fast.
Just work on getting red+green light sequences, then look at cross streets, amber lights, pedestrian crossings and vehicle sensing, crosswalk buttons etc.
See, it can get out of hand very quickly !
First tip, once you get the red+green basics working, lose delay() and think about millis() timing.
