Wireless Serial Communication Arduino To Matlab
This tutorial was on 3/9/2011This week, we go wireless! We’ll be using a set of arduino Unos, XBee shields, and XBee Transceivers that will create a Personal Area Network (PAN) for wireless serial communication. By the end of the episode, we will be able to turn a potentiometer on one arduino, and have it adjust a motor connected to a another arduino – all wirelessly! I suggest you pick up one of these to get your XBee addresses set up. Enjoy the video:)EDIT:Serial.flush. You can use the following instead:while(Serial.available0) Serial.read; You can download the files associated with this episode here:Distributed under the.Please. Andrew HarbertHello,I am trying to configure two XBee S2 modules to communicate with each other via Ardiono Unos and the XBee Pro shields.
My problem is I am new to this and not sure how to configure the XBee modules to talk to each other. I tried using Putty with instruction from Jeremy but I keep getting an error during the ATML1000 configuration portion. (His instructions work great for the XBee S1 but not the XBee S2).

I have downloaded the XCTU software but am unsure how to use and the proper procedure to configure S2 modules to talk to each other.Any help would be greatly appreciated.Cheers,Andrew. DtrSavinkovHello, Mr. Jeremy!I have some problem with WiFi Bee 2.0 (model RN171-I/NM).I have:1) Arduino Mega 2560 rev32) Mega Sensor Shield 2.43) WiFi Bee 2.0 shield4) usb-cable to connect arduino via USB to computerSo, I connected Bee to XBee2 port on Mega Sensor Shield and I can’t do any action:1) can’t connect to home wifi-network2) can’t create an API need one of this variants to realize connection between PC and Arduino, but WiFly library’s method float WiFly::version always reports -1.0. I watched the code of library – boolean WiFly::sendCommand(const char.cmd, const char.ack, int timeout) returns “false” because boolean WiFly::ask(const char.q, const char.a, int timeout) returns “false” and so onGoogle gave me no any usable information, that I can use.I will be wery happy to get any advice to fix my problem:-).
Andrew nealPLEASE HELP!!!! I have two xbee pro s3b high range 900hp radios with two arduino UNOs 1 motor shield controlling 4 dc motors, robot side: xbee s3b with high gain antenna, motor shield, arduino uno with 4 dc motors. My side: xbee s3b 900 hp with high gain antenna xbee sheild arduino uno with two axis joy stick.
Here’s what I can’t figure out. How can I control those motors without a computer just a battery powering the arduinos and robots I don’t know how the code looks. I have figured out how to do it serially but I want to cut ties with computer. Ashok KumaDear Jeremy Blum,I’m very glad to meet you, I’m a research scholar, for my project work I need to use the wireless communication system for data tracking from the tractor rear wheels, for that by watching your tutorials I have designed two wireless systems by using Arduino & Two Xbee modules (One as transmitter and other as receiver) for each wheel i.e.
Finally I have two wireless systems each has One Arduino and two xbee modules and both the systems have been connected to two laptops separately to record the data.But its difficult to use two laptops on the tractor, hence we have decided to to collect both the axles data with single laptop, but how to do that I could not understand, basically I’m an Agricultural Engineer. I request you please help me in this issue.Thanks in advance. Prakhar JainHey Jeremy! I tried the wireless communication between the two xbees as you demonstrated in your tutorial.
The the xbees the working just fine. The transmitter xbee is transmitting the values from 0-9 but the receiver xbee is receiving 3 values at once. Suppose the pot transmitted 3 thorugh the transmitting xbee, the receiving xbee displays 3 along with 2 more values that are -35 and -38. Due to this the servo is just jerking. I tried to solve the problem, but nothing worked!
Table of Contents.How Arduino MATLAB Interface Works?We normally use Arduino IDE to write and upload programs (or Sketches) to Arduino. This is fine for regular use but if you want to plot the data obtained from sensors, then the programming becomes a time consuming task.MATLAB addresses several such problems in Arduino Programming with the help of two types of processes:. Reading, writing and analyzing data from Sensors. Developing Algorithms that run as standalone program on ArduinoIn order to achieve this, we need an extra package for MATLAB called MATLAB Support Package for Arduino. This is officially released by MATLAB and is available for free in their website (you need to have an account to download this package).
Installing MATLAB Support Package for ArduinoNow we’ll see how to install the MATLAB Support package for Arduino. First, start the MATLAB Application and in the RESOURCES Tab, go to Add-ons and select Get Hardware Support Packages option.After initializing the add-on, you will then get an options of how to install the package i.e. From the internet or from a file already that is already downloaded. I’ve chosen to install from the internet.You will then get a list of all the available Support Packages.
Select Arduino and check the MATLAB Support Package. There are Arduino Support Packages for Simulink as well but we will leave it for later.Now, the MATLAB Application will ask you to login to you MathWorks Account.
If you have an account, use those credentials and login or you can create an account during installation. Next, accept the license terms and continue to download the package.MATLAB will now download and install the selected packages. Sit back and relax until it is done.Also read Interfacing Arduino with MATLAB and Testing the Support PackageAfter installing the Arduino Package for MATLAB, we will now see how to interface Arduino and MATLAB.
Connect the Arduino board to the computer that is running MATLAB and open MATLAB Application.In the command window, type the following and hit enter. A = arduino (‘com8’, ’Mega2560’)NOTE: You have to clear the variable ‘a’ using the command ‘clear a’. Programming Arduino using MATLABWe will now see how to program the Arduino Board using MATLAB Programming. For this, I will be using the Arduino Mega Board. It has an on-board LED connected to Digital Pin 13.I’ll write a MATLAB Program in order to blink this LED for 10 times with a delay of 1 second. Alternatively, you can connect an external LED with a current limiting resistor to the Digital Pin 13 and the following image shows the circuit diagram for this connection.In the file tab, go to New and select Script option. A blank editor will be opened.
Paste the code mentioned in the following section and save the file. It will be save as a.m file, which is the extension for MATLAB Programs.NOTE: Change the COM Port and Arduino Board according to your needs in the code.After saving the file, click on Run option. The MATLAB program will interact with the Arduino Board and will perform the desired option.An important point to be noted is that the program will not be uploaded to Arduino and hence if you reset or restart the Arduino Board, the program will be lost and you need to perform the above steps once again.There is another way to program Arduino Board through MATLAB, but we will see that later.
