Sir Paul, i completed my graduation in Electrical Engineering from 2007 to 2011, after my graduation, i am involved in Techno commercial jobs and almost no link with real engineering stuff. Now, I am taking your Arduino tutorial and reached up to 42 lessons, your lessons about controlling servo, stepper and DC motors helped me to decode programming of servo based Voltage stabilizers. It was real shock for my whole company, how i was able to transform Voltage stabilizer into graphs and equations....i really wished to have top quality education form US or UK, but you are making my dream come true.. i salute you for your lectures and transforming my life/Thinking.. Thank you Sir, may Allah help you always. Ameen

i love your lessons i have finished the arduino lessons and they were great

Most excellent makes life easier. The addition of the BNO055 would be a nice upgrade. See you Saturday. Thanks, Paul.

This is my holy grail. he whole reason why I stared with arduino in 2017.

for everyone who gets stuck like i did. It makes a huge difference using if (cmd=='f') what i mean is the little sign 'value' instead of using "value" i always used " value" before and never had problems but i guess this is only the case for strings great lesson as always, learned a lot. Thanks Paul

This is super fun and easy, I thought that there will be a weird command for the Bluetooth to work. I'm really excited for the next coming lessons.

I am very interested in closed loop control. I suppose you are finished with these robotics tutorials, but the car needs a real control system. Your lessons are most excellent!

Thanks Paul. Great lesson, this is way too easy:>) adding the other things velocity, distance and numbers was very straight forward. I think the robocam has some recognition on it as your face was sporadically boxed. Enjoyed this. See you for the next lesson.

I had coding issues as well, good lesson.

Outstanding and excellent lesson.. Thank you sir.

I like the idea of using the BNO055 with the robot. Maybe the magnets in the motors will cause a problem ? How about using the jetson nano to track the robot visually, keep it straight and/or steer it around a course ?

sir you are fantastic, just fantastic

Im late today, I got a tardy :( Great Class!!

Is your Arduino tutorial over??? Loving your stuff....

Awesome video. I did the homework. Still having trouble calibrating the theta to set the turn angle but just hard coded a tweak in there.(added a quarter ms to delay time). Had a weird glitch where the ble wasn't waiting in my setAngle function and skipped past all my if statements. Came back after dinner and changed the character and extended the delay from 200 to 400 and it worked fine. Changed it back to the original way I had it and it worked fine. Same code, same syntax. I stared and compared for a good bit, so don't know what was going on. It's usually operator error for me so >>

I would like you to include the BNO055 in these lessons.

Hello Paul, Very awesome tutorial on bluetooth !!!! Very interested in bno055 closed loop control of robot !!!! You are the best ever !!!!!!! Rick

Comparing version V3 of the car with V4 - the V4 shield now has an MPU-6050 (Accelerometer and Gyroscope Sensor) module in the place previously occupied by the Bluetooth module on the V3 shield. The Bluetooth option is now provided by an ESP32-S3-WROOM-1 board which sits above the ultrasonic module; the ESP32 board provides generic Wi-Fi & Bluetooth LE (as well as a camera). I've connected OK to the Bluetooth and can send 'commands' (f, b, l & r) but the car doesn't respond - in a similar fashion to the supplied Elegoo Uno board I suspect the ESP32 has been preprogrammed and so it's maybe expecting different 'commands'. I shall persevere - it's not a problem but an opportunity to learn more! I do have a 'spare' ESP32 module that I've previously programmed using the Arduino IDE so I can look at programming that and replacing the one on the V4 - the latter will then be kept safe with the supplied preprogrammed Elegoo Uno if ever I want to go back down that route!

Thanks for another great lesson sir!! I am thinking to make a replica of elegoo smart car all by my own, so I would love a lesson on the BNO055 sensor with the car but the sensor is costly here, so if you can suggest some other sensors or any other method for the technique please reply me sir. Again, thank you very much for the lesson!!!

I wonder how far the bluetooth signal goes, I may just well have to test it out 😁 👍

Bluetooth stopped breaking Paul's heart? Cool.

I would love a lesson on the BNO055

I'm having a problem with my Bluetooth module. I think it may be defective... It will connect with Smart Robot Car app on my IPhone, and then immediately drop. However, if I comment everything out including the "Serial.begin(9600)". It remains connected. If I only leave the "Serial.begin(9600)" uncommented, with everything else commented, I'm back to it connecting then immediately dropping. It appears to be a problem with the initial handshaking caused be the Serial.begin? I can't figure out how to order a new Bluetooth module. I couldn't find it on amazon or Elegoo.com The only marking the board has is "ZS-040". Any suggestions would be greatly appreciated. Thanks.

Please make tutorial of WiFi robot car.

Sir, please make a tutorial on Bluetooth module (HC-05) on Arduino...

Try to use tv remote for ir

Gut

Now that school has started and your house has sold, will we really have Lesson 15 next week? Or will it have to wait until you get settled again? We should have enough to keep us busy figuring out what to do next!

You missed curly bracket

I hope that it will have a way to use both iOS and Android. The given module works with iOS, but the app kind of suck and doesn't show how to use it.

Im interested to be with you in control room☺️

Is anyone else having issues with pairing? My phone settings show the car is available, but the app isnt finding it.

My motor driver outputs are not identical.. That's why my car go right side faster then left side.. by doing a simple math my car goes almost straight in the open loop system.. After this tutorial I'm going to take 9 axis sensor tutorial..

great stuff , sorry I missed it..... May I suggest a solutiion concerning the Rx,Tx, (UART) plugging/unplugging the USB etc... You can simply use "SoftwareSerial" on pins 10 and 11 for example. All you need to do is add the following library at the very top of your code..... (no need to download anything it's allready standard issue in the ArduinoIDE 13 and earlier...) #include you can read all about this functionality at: www.arduino.cc/en/Reference/softwareSerial It's pretty straight forward and very handy stuff indeed.... Oh, and one more thing... closed loop control... definitely interested ! As I mentioned before, I am still trying to incorporate the Micro:bit in my robotic classes because it has a compass and blutooth already built in... and it's kids (k-8) friendly... P.S. btw are you serious about the "side kick" - control room thing? applications open? Age limit? ...any prerequisites needed?

Start of robot dance and end of robot dance delay is about 100000 milliseconds make it 2000 miliseconds sir!

Hi

This time I have set the reminder.... But it seems I'll be at work... again, missing the live version..... It's been a hectic week at school.... papers, plans etc....we are all preparing for the worst.... "the online mode"... which is expected middle of october... BTW In case I don't get home on time.... will there be mention of the BLE vs HC-06(05) pros and cons issues.... That would definitely be one of my "live" questions.... (I have read just about all there is over at Martyn Currey's blog but still I'm a bit confused...) www.martyncurrey.com/bluetooth-modules/
