Issue controlling Flux Capacitor with IR remote

[anon80309339]

I have an UNO R3 board that is the basis for a replica Flux Capacitor project I am doing. This is my first time using an Arduino, and first time looking at C++. I'm only part way into my build, so I currently only have the UNO and DFPlayer working (no lights yet).

My issue is: when I press a button on the remote, nothing is happening. From the code, I know that a sound plays and then a light sequence will start up. The startup sound plays every single time the UNO powers up. Sometimes Button 7 and Button 9 will play a their respective sounds after startup, but none of the other buttons will work. After that initial play, Buttons 7 & 9 do not respond.

I have a 17-key remote that uses the NEC protocol. I have verified that the remote and sensor work via other sketches. These sketches also helped me find the button codes. When getting these codes, I also saw "Unknown" Protocol on the serial display.

This project is based off another, and the code used is mostly the original code. My only alterations were an attempt to update IRremote from version 2 to 3/4, and to remove a "Rainbow Mode" setting.

// Created by RadBench: youtube.com/radbenchyt
// Made for A flux Capacitor with a 10 light NanoLed strip
//Modified to Update IRremote from V2 to V3/4. Removed Rainbow Mode.

That semicolon belongs to the previous line of code.
Leo..

@anon80309339

      if(i = 0) {

you have this many, many times throughout your code. That is an assignment, comparison is '=='

That would be the first thing to fix.

[anon80309339]

I checked the original unedited code for this project, and that semicolon wasn't there. Seems like my finger slipped.

[anon80309339]

I understand using comparison for the buttons and the different modes, but what is the benefit to using comparison for the LEDs? Is this a change that will make the code more efficient?

I know the light modes worked in the original build, the builder demonstrated them all in a video. I'm a bit hesitant to touch that part of the code, I'm not good with coding, and I don't want to mess up the most impressive aspect of this project: the light sequences.

[blh64]

@anon80309339

I understand using comparison for the buttons and the different modes, but what is the benefit to using comparison for the LEDs? Is this a change that will make the code more efficient?

You are assigning a value to i and not comparing it which changes what the code does.

[anon80309339]

As the code is now, its assigning: if(i = 1) {

The code should be like this (equal to): if(i == 1) {

I assume that code after if(i = 1) { is controlling the blink sequence and color of the LED lights. Why is using == is better for the LED lights? Am I wrong about what that part of the code does?

Could these numerous assignments in the code prevent the IRremote from responding? Did having to update the code from IRremote 2 to IRremote 4 cause the (previously working) code to break?

[blh64]

@anon80309339

Why is using == is better for the LED lights?

why do you keep asking the same question? if() statements use the comparison operator '==' to test for a condition and, if the condition is true, execute the code associated with that if() statement. It sounds like you might need to take a step back and spend some time learning C/C++ before tackling this project.

[anon80309339]

I asked my initial question because I am seeking guidance in trying to troubleshoot my remote. This was working code, with a working remote control. I want to get mine to work.

You're saying I should this change code at the end of my sketch, I have no issues with that. What I'm having trouble with understanding, is how changing that code helps with troubleshooting my remote problem. Is how it's currently written causing conflict with IRremote? If it is, please say so.

It doesn't make sense to me to change around code if I have no way to test it.

[blh64]

The most likely cause of your remote not working is that the FastLED library turns off interrupts while it is clocking the data out to the LEDS and the IR library uses interrupts to receive the bit stream.

As for the other code, it is still wrong, regardless of whether or not it is impacting the rest of your code.

Another example of wrong code that doesn't impact your receiver:

@anon80309339

  Serial.begin(115200); // Initialize Serial Monitor Output @ 115200 baud
  ...
  Serial.begin(9600); // Initialize Serial Monitor Output @ 9600 baud
  ...
 

You start out at 115200 baud and then switch to 9600 baud. Depending on what baud your serial monitor is set at, you will miss either the first part or the later part.

You only need to start the Serial communication once.

[anon80309339]

Thank you for the first comment. That gave me some direction for testing. You are 100% correct. I also made the changes you mentioned too.

I created a sketch where I took out all the FastLED code, and I can get all the buttons to work/play sounds/print output to serial.

I also tested with a few bits of code on the FastLED Git that are supposed to help with the interrupt issue

#define FASTLED_ALLOW_INTERRUPTS 0

#define FASTLED_INTERRUPT_RETRY_COUNT 1

I tried both of these (individually), and could get the buttons to respond for a short time before they stopped responding.

More testing.

I too am building a RadBench flux capacitor and getting the original sketch to work as shown in the YouTube video has been challenge. At first, nothing worked, but I read in the video comments that the most recent versions of the libraries may not be compatible. So, through a process of elimination, I got the LEDs, the IRremote and the DFPlayer working by trying different versions of the libraries. Here are the libraries that work for me:

IRremote is version 3.6.0
DFPlayerMini is version 1.0.3
FastLED is version 3.6.0

Another problem was getting the music/sound effects to occur with the correct LED effect. The SD card must have effects numbered (.0001 through .0006) and sorted by the date modified. The files must be in a folder titled MP3.

IRremote-LED Light Chase-Song/Effect Sound-File Name
Start Up (Power On)-Rad Speed (White)-EngineStart-.0002
Button 1-Time Travel-Delorean Time Travel-.0001
Button 2-Smooth Chase (10 Lights)-StartupShort (no beeps)-.0003
Button 3-Film Speed (White)-StartupLong (alarm beeps)-.0004
Button 4-Film Speed (Amber)-Startup 2 (low beeps)-.0005
Button 5-Rad Speed Amber Default Speed-StartupShort (no beeps)-.0003
Button 6-Rad Speed (White)-StartupLong (alarm beeps)-.0004
Button 7-Rad Speed (Amber)-Startup 2 (low beeps)-.0005
Button 8-Rainbow-Startup 2 (low beeps)-.0005
Button 9-N/A-BTTF Theme Song-.0006

Line 109 caused the wrong sound effect to play. Changed "myDFPlayer.play (2); //Play mp3" to "myDFPlayer.playMp3Folder (2); //Play mp3". It works now.

The only IRremote button that does not work fully is Button 1. LEDs work, but no sound effects.

After I figure out the button 1 problem, I plan on updating the sketch to work with the newer versions of the libraries. Hope this helps!

[pathollywood]

Any new updates on this? I am building the same thing and I can't get button 1 to work correctly and I somehow cannot get the volume up and volume down buttons to work either. The pinout diagram that was provided did not have anything hooked up to the IO_1 (volume down) or IO_2 pins (volume up) on the DFPlayer module.

[arc1985]

My situation: The mp3 file would not work through the flux player, but would work through my computer. The lights worked fine.

I used Audacity software to reformat the mp3 file. After doing that, it worked through the flux player.

My flux capacitor sounds and associated effects are now working.

Not sure about the volume, I haven’t tested it.
