Hi,
I m new in UE,I basically unity developer,I plan to shift to UE for getting AAA Quality out.I tested this on UE 4.20.3 UE4Duino 2 UE 4.20.2 version on my UE 4.20.3
its not working - Port not Opening
while running UE i try to open Arduino software and run my program its working on Arduino software.So my understand in new code UE not creating/opening serial port

yuanny THANK YOU for spotting that one!! Can't believe I did that!
Shauntezuma and Praven P Jose Can you check if it's working now? Thanks, guys!

Just found this plugin and think it's perfect for what I am trying to accomplish. I'm 100% new to Arduino, never looked into them until I found this plugin. I will probably have lots of questions, but first off is it possible to control more than one Arduino with UE4 using this plugin? Also is there a good tutorial you can point me towards to get me going with this plugin?

Quick questions:
1. Is the port speed fixed at 9600?
2. How many ports are supported at 9600 if its fixed?
I want to transfer a lot of information really quickly. The information will be coming from a triple redundant flight sensor system on a high quality flight controller. I can get data off the flight controller as one or many streams, but it will need to be a lot of information coming to UE4 over serial.
I could do this with Ardupilot, but I want to do it with UE4 just for the challenge. My UE4 flight simulator worked out and now I'm cocky. Gonna make a UE4 controlled drone. It may even happen on a single board computer on the drone. Lattepanda seems to be offering me a ridiculously overpriced way to pull this bad idea off and I can't resist.

You can connect to several Arduinos, as long as you know the port numbers. Just create a different variable for each connection and never forget to close them before the end of your game.
I don't know about any tutorials, but the images that come with the plugin might help you. And the brief explanation in the first post of this thread.Freelancer Game Dev Generalist and Unreal Consultant | Portfolio

2. At 9600 or otherwise, as many ports as Windows can work with. Even with numbers of 10 and above.
BTW, if you'll want to transfer a lot of different variables at once, you might want to create some kind of protocol, like I briefly described in this post.Freelancer Game Dev Generalist and Unreal Consultant | Portfolio

EDIT: Nevermind. I just saw the release note for version 2.2.3 that fixed the bug which was preventing port from opening. I have 2.2.2 installed in my plugins. I will get the updated version! Thanks for being on top of that and fixing the issue already!Last edited by dixonian89; 10-16-2018, 11:20 AM.

Presently stuck on noise. I based my system on an ARM M4 controller, its a rocket on the breadboard but holy smokes is it prone to reset on electrical noise. I'm finding that when it says optional capacitor on the diagrams, what they really mean is "only a noob wouldn't put one there."
edit: just passing through then off to download and setup the plugin.

I filtered it in a project by storing the values in an array and using the array's average value as output. The bigger the array, the stronger the filter. I got very good results at 60fps with a 3-values array. Smooth and still close to the original signal. But for higher framerates, more values might be needed.Freelancer Game Dev Generalist and Unreal Consultant | Portfolio

Hey there,
I am using the plugin for a current project of mine in UE 4.19.2 and can`t get it to pack. I am getting following error message:
UATHelper: Packaging (Windows (64-bit)): LINK : fatal error LNK1181: Eingabedatei "C:\Program Files\Epic Games\UE_4.19\Engine\Plugins\UE4Duino\Binaries\Win64\UE4-UE4Duino.lib" kann nicht ge�ffnet werden.

Apparently the file UE4-UE4Duino.lib is missing: I thought that it somehow got deleted so I downloaded the zip again to check if it was in the originally downloaded content but it wasnt. It would be awesome if anyone could tell me what I`m missing here.

//Edit:
After browsing countless other threads now, I figured that I overread the instructions. I put the plugin into the installation folder of Unreal and not into the Project folder. After putting it into the project folder and compiling it, it was packing the project as expected.Last edited by Sh4rp_; 11-21-2018, 04:05 AM.

Here're the binaries for 4.20.3.
I see a lot of folks always asking for step by step tutorials...I appreciate this so much I'll try to knock a few "hello" world tutorials in the next few days.
Best,

Hi. First off, thanks for writing this plugin, it's precisely what I need to complete my CS project!
I am trying to accomplish something similar to what game_master_jodan did with the UE4Duino plugin here:
Originally posted by game_master_jodan View PostThis is the code for my basic arduino 4xrelay board. I use a baut rate (arduino and Ue4) of 1200, seems enough to me. What ever I write to the serial it gets parsed as a integer (ParseInt). So... when I write 10 to the serial relay 1 gets switched off. When I write 11, relay 1 gets switched on. same for 20 21 30 31 40 41. There is no trickery just write according to the docs to the serial port. Works absolutely perfect for me and a big thanks to the creators of this plugin and Ue4. Hope it helps someone.
(slightly modified Arduino code
// Basic 4 Realy board connection
// Each relay is turned on and off when sending 10 11 20 21 30 31 40 41
// You can here them click as there state changes from off to on and on to
// off.
// You will also see the corresponding Red LED on the 4 Relay board
// light up when the relay is on.
// define names for the 4 Digital pins On the Arduino
// These data pins link to 4 Relay board pins IN1, IN2, IN3,IN4
#define RELAY1 13
#define RELAY2 7
#define RELAY3 8
#define RELAY4 9
long mydata = 0;
void setup() {
// Initialise the Arduino data pins for OUTPUT
Serial.begin(9600);
Serial.setTimeout(10);
pinMode(RELAY1, OUTPUT);
pinMode(RELAY2, OUTPUT);
pinMode(RELAY3, OUTPUT);
pinMode(RELAY4, OUTPUT);
}
void loop() {
while (Serial.available() == 0) {}
mydata = Serial.parseInt();
if (mydata == 10) {
digitalWrite(RELAY1, LOW);
}
if (mydata == 11) {
digitalWrite(RELAY1, HIGH);
}
if (mydata == 20) {
digitalWrite(RELAY2, LOW);
}
if (mydata == 21) {
digitalWrite(RELAY2, HIGH);
}
if (mydata == 30) {
digitalWrite(RELAY3, LOW);
}
if (mydata == 31) {
digitalWrite(RELAY3, HIGH);
}
if (mydata == 40) {
digitalWrite(RELAY4, LOW);
}
if (mydata == 41) {
digitalWrite(RELAY4, HIGH);
}
}
This is my first time trying to use Blueprints so I am sorta confused.
