Activating Different Led Sequences with mobile app

johngtaxi · June 19, 2022, 10:41pm

Hello,

Currently have arduino uno setup to do some basic Led sequencing functions. But came across some coding on YouTube that has like 7 sequences all in one coding. Wondering how one goes about activating a specific sequence by making a mobile app? Or do I need to be using the esp32? Below is the code I found with multiple sequences.


#define t   30
#define t1  20
#define t2  100
#define t3  50

void setup() {
  // set up pins 2 to 13 as outputs
  for (int i = 2; i <= 13; i++) {
    pinMode(i, OUTPUT);
  }
}

The Uno has no internet connectivity or Bluetooth.

johngtaxi · June 19, 2022, 11:08pm

Sorry, should have specified if I use a Bluetooth module with uno.

What do you mean by "activating a certain sequence"? In what sense should it be active? Can you break down the desired program actions for us, it's often helpful to provide an example. In this case it it not possible to guess it from the code since you didn't do any work on it.

PaulRB · June 20, 2022, 11:41am

It's not great code. The problem with it is that it is written in a style called "blocking code". That means that the Arduino will not be able to react to input from an app, or a pushbutton, or anything else. It won't be able to switch between sequences until the current sequence ends.

I suggest you look for sequences that are written in a "non-blocking" style, or learn how to re-code those you have using non-blocking code.

johngtaxi · June 20, 2022, 12:15pm

I understand what your saying. That’s what I’m trying to learn as to what coding would be needed in between all the blocks per say that say run this sequence or that sequence. I guess what’s the code called ? I don’t mind researching and learning it.

Just not much all day searching cause of not knowing exactly what I’m searching for. Lol
