No one can explain it better. Thank you Paul for such a wonderful lecture. You have explained everything clearly leaving no room for doubts. One of the best lessons I have come across. Keep up the good work.
Another great video! I love that you showed us with a completely blank program the gps module still streams data over the serial port. That's such a great visual.
Nicely done. Thank you for not editing out finding the errors. It is part of programming.
Wow! We’re going back some years and still getting excellent videos. I just ordered one of these guys for my robot car. My goal is to make the car go to waypoints that I program into it.
Great series very engaging presentation style. Thanks Paul.

Thank you for taking the time to teach these lessons.
Thumbs up every time - I have learnt so much with his detailed and precise tutorials. Thank you Paul
You're awesome man. That buffer clogging was messing up my data. You explained it well.
Excellent video series Paul. Hope you will continue this good work. Thank you very much.
Youre a fantastic teacher helped me sort a project out in no time flat !! thanks a million!!! can hardly belive how simple arduino makes things
Thank you Paul, this has been so tremendously helpful - not many arduino tutorials are as engaging and well explained as yours!
Thanks for the kind words.
Amazing work, amazing voice, amazing lesson!
Thanks
Thanks for the kind words!
Amazing comment too
This is just what I needed! Keep up the good work Paul.
hello . i want to ask if it is possible to use this gps sensor with arduino to make a gps survey instrument which can do the gps correction automatically and so it can be used for surveying with an acceptable precision.
Hi, were you able to make it work with the Arduino? We are trying to do the same thing, but can't get past the first step of just reading data from the GPS. We connected it and both boards had power. Then we loaded the empty code. When we clicked on the viewer, not data was being transmitted from the GPS (even after trying different baud rates). Can you help? - thanks
Great video! You are one of those teachers that can just make complex stuff a lot simpler. By the way, I saw there is also a GPS.speed() function for the Adafruit library, and it shows it in knots. Is that a good way to find speed?
Temp/pressure worked, but not GPS. GPS worked, but not T/P. It was the ClearGPS() that did it for me. Thank you, man! Subbed!
Thank you Senpai. You were the one who told me to make this in the live stream about starting an Python Series.
Truly informative! Thank you for your dedication to helping others learn.
Hi. Nice tutorial. Do you need an external antenna?
Thank You.
Marc.
oh wow! u brushed up my programming skills back to norm. thanks a lot.
Ur the best resource for me to deal with Arduino programming ,,, love to see Ur vedios 😍😍
Thank you Paul for sharing your Arduino knowledge. Great tutorials!
Craig Clark Thanks Craig, glad to hear you are finding them useful.
Can't you ignore the data unless it reads $GPGGA correctly so it does not come over corrupted? only accept it if its good?
Mcwhotter i actually can't say how grateful i am to you,you've done so much in my life and you've made my dream comes to reality.i have been willing to learn arduino programming since i was small and all attemp to know it proved abortive..i went online to search for videos but i couldn't see one that suits me..many videos lied,i lost hope and at some point i stopped disturbing myself thinking that the programming world is not meant for me until one day when i kept disturbing youtube and i found one of your arduino videos,i taught you were like others too and i downloaded one,i couldn't say how much happy i was that day when i realized my life has changed.....you're such a wonderful being,i don't know what to use and compensate you cuz i don't have anything....but i really appreciate what you've done in my life......one more thing? Can you please make videos on 7segment display with arduino and bluetooth module with arduino??
❤❤LOVE FROM NIGERIA
One my favorite guy!! learned a lot!
You Are great mr. Everything that you are doing in every tutorials is verry nice.
Thanks for posting this video I appreciate the time you take to explain everything also its "kool" of you writing the sketch in real time. Subscribed :)
Excellent tutorial. The best part was the mistakes giving us newbies some hope. :-)
in 17:48 the reason for using the & sign is to pass the memory address of the software serial object. this is done as it prevents making a duplicate of the software serial object Saving memory which is crucial on boards with very small memory (like arduino uno which has only 2kb of memory). I checked the adafruit's library file and looked for the parameters(the thing which you passed in to create the object) and the constructor(the thing which creates the object) is looking for a pointer.
you're awesome. thanks for the effort. Is there any way to just read speed?
Thank you you are my oline teacher i will follow you :)
Good tutorial!
but your clearGPS has a bug, assuming that the GPS messages always comes in a specific order ( I think they do ).
It means if you see the messages being printed out of order you are printing GPS values from two DIFFERENT reads from the GPS, might not be a big issue but one worth knowing.
I would look into clearing the serial buffer itself in your clearGPS and only accept GPS values if they come in the right order.
But beside that small bug I think the video was great!
hello, this video is brilliant. thank you ! can i use an arduino nano for this
Hello there, thank you for this video. I just have a few questions. Is it possible to integrate this diy gps tracker to Google Maps? If yes, how will you do that? Are you going to use GPRS/GSM or you'll use a radio frequency instead? Thank you.
I really enjoyed this tutorial.
Thanks
Maziar Ghorbani Thanks!
6:18 _"You have to _*_KILL-"_* I swear I was just hopping backwards in the video and then this 😂 Haven't seen this video in weeks so I surprised myself 😂 Thanks for the help though!
Couple of quick pointers:
Around 17:43 you mention not knowing why you need to use & in front of your variable. This is known as passing a variable by reference (as opposed to pass by value), which means the method being called will have a memory reference to your variable rather than a copy of it. Try googling c pass by reference for a more in depth explanation and why it can be beneficial.
Around 26:30 you mention that void indicates that you aren't passing any parameters to the function or getting any back. This is wrong, void (or int/string/etc) indicates the return type of the method, and in no way says anything about the method parameters.
Wow using this video to help me with work i'm doing for my NASA internship
the video was very informative, thanks for sharing it with us.I need a small guidance for my project on location tracking using a SIM908 module interfaced with Arduino.The main aim is that, if you call to the sim present inside the module, it should store your no. and it has to send back the location to your no. .
can you help me with this code?
What software are you using to record this? I really like the layout.
very helpful video, but if i am already using Digital pin 2 and 3 , which other pins would work and what would i have to change in the code? thank you.
I just started a crazy ideas folder too! I bet Pauls is definitely up to par =)
My crazy idea folder is crazier than anyone's crazy idea folder. You really do not want to see whats inside.

have you test how the accuracy of that gps...say you put it stationary and observe how does coming data deviates over time? Very nice tutorial...
+fnjyusername using the adafruit library I tend to have about 10 feet drift with good fix. Drift is worse if you only have a few satellites. I can get better accuracy on the device I build with BBB which develops the NMEA parser from scratch.
Awesome video! Is the location of the device able to be monitored wirelessly from a computer while the arduino is moving around? Thanks! (I would like to use this idea for a high altitude balloon.)
+themagicJAR48 Yes, the issue is maintaining the wireless link, which will involve legal issues, safety issues, antenna design and other engineering challenges. We have maintained a live telemetry link to High Altitude Balloons for over 70 miles downrange. It is a tough problem.
Can I use a NEO 6M GPS module for range upto 800 metres? or shall i use a gps shield? which will give better results?
PS- Your videos are really great :)
I'm totally new to this. What boards and connectors are required to make this work? I am starting totally from scratch.
very useful lesson, thank u
That extra zero and that semi-colon were killing me. It's like watching Dora the Explorer, yelling at my screen.
With a void function you can still pass parameters to it, it'll just not actually return anything, you can also make a function that does return something with no parameters passed to it, especially if you're dealing with global variables.
Another question is..
Is the SoftwareSerial.h is already included in the arduino application? The version of arduino application that I am using is the latest one. Thanks again!
Hi Paul, i just wondering, how big is the resolution of that GPS coordinate?
can we make it to small resolution like we can get different coordinate in every 1 meter or maybe smaller??
i'm have big hope that you will explain, thanks
hello paul i want to ask something, i build project gps with arduino, i want to show name of location to display lcd 2x16 with longitude and lattidute for set point, but when i try to show long and lat to display is not worl can you help me ?
You like adafruit sensors.
Could you please make video explain how is the GPS and IMU works together with arduino or raspberry pi.
I think you can clear the serial buffer with Serial.end() too.
So you don't mix up NMEA sentence from different timestamps
Paul, getting hold of an Adafruit GPS unit here in the UK is impossible and there are cheaper units. As I don't need the same one that will operate at +60k feet I am going to assume units should produce equivalent data streams
17:45 - Pass-by-reference has a couple of benefits: better performance since it doesn't have to copy the variable, and the ability for a function to "return" multiple items instead of just one using the normal return.
17:46 the reason for " & object_name " must be that the gps for the add in address location .....if when we r not using pin 0,1...we must have to tell the arduino to go to GPS tracker and access the file or data located address...so that's the reason I think we need to write " & " to the the data from a particular address
its like a pointer
@@siddheshgawali7764 It's the memory address of that variable.
Awesome just what i need thank you
your tutorial is very usefuly . can i get program using PIR security based using aurduino please?
do you work for Escondido high school?
if so, I was a student there
Sir I am big fan of all of your projects kindly make GPS land leveling with arduino...
HI Professor Paul,
How do you setup the GPS at the beginning.. Because I receive data but mostly garbage data and the few good strings. thx
Hi
Can u tell me is it possible to improve my accuracy by using 2 GPS module NEO - 6 M (comparing information)?
I mean in Arduino or create app in Delphi XE8 or C#, or any other methodes?
Are you still making GPS trackers?
I am trying to find out how to build a very simple one. Essentially it would be capable of sending its location on demand. Any opinion? Do you think this hardware is out of date? Would you use anything else now?
Hi! I bought one of these and am currently using it with an Arduino Mega 2560 and the only way that I can get something to display on serial port is when I do the direct wiring otherwise is not printing anything on the serial even though he seems to be getting a fix when I do the direct wiring.
Any suggestion?
Hello sir, thanks for these awesome lessons. I would be more thankful if I could get some lessons about the wireless data transfer through arduino gsm module.Thankyou sir..
I'm using the same setup and code as you but then I can't seem to get the data as fast as you. Seems like the GPS data coming in is being delayed, I get the readings for GPGGA and GPRMC every 2-3 seconds. Do you know what can cause this?
Maybe because I'm inside a 5 story building?
the "&" sign in the init of the GPS is for pointer referencing.
Good 1! keep it up!
Could be without work conecatado Computer wing , exatas to send the information wirelessly and have as cellular UN receivers this can ?
Good day sir ! is it okay if we use gizduino rather than arduino? and can you tell me the version of your gps module? thankyou.
Hi Paul
Thank you for all your videos - they are superb. I have a question on the GPS. I connected Tx and Rx with the Arduino as you suggested but did not get the streaming data. Would it be because I am in the UK and if not would you please have any suggestions. Thanks
Tx to Rx, and Rx to Tx, right? With that it should work anywhere on earth.
ok thanks let me check my wiring
hi thanks for tutorials
i want to ask you how i can send the locations ( longitude latitude ) with GSM to my phone like "SIM900 GPRS/GSM "
Maybe I'm getting ahead of things, but could you set up an interrupt handler to process incoming characters and place them into a temporary buffer (one for each sentence), then copy that temporary buffer to a completed when complete, so that your loop program would always have access to the latest and greatest sentences?
+Chaplain Dave Sparks Certainly not saying that these lessons show the best way to do things. What I am trying to do is get High School students playing around with technology. My expertise is not in programming or micro controllers, so I am just trying to show them a way to get it work. When they get to college they can learn about doing things the best way.
very nice tutorial
Thank you too much Mr. Paul.
Does the *.ino work with Blox Neo-6m?
You're so Awesome....
hlw sir, its my fist time to watch the video but prior to anything, i have the project relating to integrating gps with desktop computer system. so i would like to know if after uploading the codes to arduino can i use the external source of power to make it work at distance?
干得漂亮
这个老头讲的挺好的
nice video. thanks !
can i do gps tracking and have a relay on off function at the same arduino system together?
Hi there,
I've been following current tutorial exactly the way it is, and everything is working the way it is supposed to be, but I am not getting two required NMEA sentence. It looks like programm sentence (GPS.sendCommand(PMTK_SET_NMEA_OUTPUT_RMCGGA); ) is not working at all. Could you, please, explain the way for managing such sentence.
Thank you very much in advance for your tutorials.
Have a good day.
Seems like the read buffer only stores one sentence at a time. The module should specify the buffer refresh rate. To be sure you are grabbing accurate data all from the same loop frame, you'd want to first set your read loop to delay at the module's buffer refresh rate, and then parse each of the total number of unique sentences the module provides. This is just a single loop for initialization. This way, you can determine and designate a start point that aligns in time with the 1st sentence you want to keep. For example, if there are 4 unique sentences that each refresh at 900hz, you can set the start of your 1st main loop to 900hz * 4, and then offset it if your target sentence is not the first in the loop frame. Then, you can initialize a second loop in the same way for the second desired sentence. This way, you're guaranteed to never miss a desired sentence, and the two you acquire in a given read loop frame will be guaranteed to be from the same loop frame of the module. Without doing this, even if you get a "C" sentence and and "A" sentence, you have no way of knowing if they both came from the same loop frame off the module. One of them can still be old data unless you ensure your reads match the refresh 1-to-1.
what Arduino and gsm chipsets did you use?
The & that you put in front of mySerial is sending the memory address of mySerial to GPS. You will see * before a variable that is memory address, the *says put this value where the memory address points.
They are pointers.
Sir can i use Module GPSNEO 6m to do the same job.
Hey Paul, I am using neo6 gps, and I am unable to get values on my Serial Monitor, I have tried both adafruit and tinyc++ Library. Could you help me with it?
Would not that character c be overwritten every time its in the loop? its not happening but it should, right?
wery naise your video
am stading your all modyool programing video thanks sir
(am frem india ) thanks for waching this video
Hi Paul, I've got one question is there a posibility to send data from this tracker remotely without GSM/GPRS module??
W3bT4l3nt I have used an ehternet shield and then sent data over Bullet Radios, but this requires antenna and line of site.
Why 1Hz ? Adafruit advertises the device for 10Hz. Is it not good enough to achieve that and remain stable? What kind of problems did you experience with 10Hz operation?
I hooked everything up correctly(5V to VIN, GND to GND, RX to 0, TX to 1), and have the correct baud rate, but I'm not getting anything in the serial monitor. I know my Uno works. Is it possible I have a bad GPS module or is there some setting thats not right?
Red LED on the GPS breakout blinks every so often.
adr127 I too ran into this problem, did you find a solution or the reason why?
I too have the same problem. Did you find any solution? Please share!
Could a Raspberry Pi 4 be substituted for the Arduino I would be using the Adafruit Ultimate GPS breakout board, a huge concern is the software compatibly.
Love your videos, never stop!
better would be to look at my GPS project on the Beaglebone black. That would be much more similar to the rpi
@@paulmcwhorter Thanks I will give it s go
@@paulmcwhorter Thanks Paul will give it a go..
how much time you took to locate the 96000 baud?
is this reliable on a quadcopter?
Your link does not have GPS lesson 22. Instead it is Arduino Tutorial 22: "Using Active Buzzer to Add Sound to Your Projects". Can I get a link to this lesson?
Hello paul do you maybe know why my GPS is printing any information on my sirial monitor
At 31:30 you talk about not pausing the program because the data is coming very fast. So my question is, to speed up the routine just a little bit more, instead of Read, Parce, Save,Read, Parce, save - do Read, Parce, Read,Parce then Save, Save. Just an idea. I don't have one of those GPS devices to try it myself.
