Having only programmed desktop software for years, I find this AWESOME AS HECK. Embedded systems seem like a lot of fun. I should buy myself an Arduino

[@devdylan6152]

oh i built one of these before :) . I became known as the strange kid at my college who would always get stopped by security and bad searched. I was the embedded systems lead and the president of my colleges tech club, and would walk around with a hiking back with drones and this guy strapped on the outside with bungee cord XD. inside my bag was tons of electrical equipment. it didn't take long for all the security to know me. AS A SIDE NOTE: !!!!! I SEE YOU USED THE ARDUINO IDE AND SWAPPED OFF TOO VS, TRY OUT THE "ARDUINO PRO" IDE. It has a lot of new features and integrates with git repos directly and a lot more.

Found it today Lmao! i got shocked

1. Cool hacking of the bluetooth software protocol and the hardware replacement :) 2. This car seems to be too fast/agile for AI based control. And has lots of provisions for future upgrades. 3. I was surprised to see a sponsored content, but no problems, another great video altogether. :)

[@javidx9]

I'm ok with sponsored content providing 1) They dont push me to be favorable towards the product, 2) it's in some way relevant to the channel 3) I can extract some sort of informative content from it and 4) They put me under no obligation to even use it.

[@meisakayukara8058]

I got one of these cars as a Christmas gift a while back, and was quite interested in how the included Bluetooth module worked. It turns out that it is not proprietary or anything like that, instead it is actually a "Bluetooth Low Energy" or BTLE device, which to my surprise is not at all compatible with traditional Bluetooth, and to interface with it requires writing an application to use the BTLE API with a BTLE compatible adapter. In my case, I used a Raspberry Pi with it's embedded wireless module and an BTLE library for Python to write a little program to control it. Which was a little more involved, but gave me the ability to send data wirelessly. I made my program visualize all the sensor outputs, including the Ultrasonic readings, as well as drive with the keyboard. It was fun for awhile, but it ended up finding a home on a shelf after a month or two.

Awesome! Next step: interface with a steering wheel and pedals controller. :)

Great video, been following your channel since I decided to give C++ a go and was looking at this kit to play with. Do you have any recommendations for someone wanting to learn embedded systems programming?

[@javidx9]

Thanks Pedro. Regarding beginning embedded systems, it's much easier if you are familiar with programming generally first. That's because embedded only introduces new things to worry about, as exploiting embedded properly also requires an awareness of electronics.

[@BrekMartin]

Cool, A hardware vid. I’m out the back of Bungaminfi (a place I made up), and can’t watch, but looking forward to it. I hope the smart part is robot arm throwing vehicles in front off the road.

In some alternate (perhaps nonexistent) universe where people start their coding journeys not by printing "hello world" to the console, but instead by outputting"hello" through the speakers, I guess they use javidx9's "hello" sound recording because it is friggin awesome.

[@Dimmerr]

Damn, wanted you to put it all together, add WASD movement and a camera on it which streams to the pixel game engine and then drive it around.

[@KeyboardNewbie]

It's an ultrasound sensor at the front, but maybe the camera for the line following parts could work

[@VincentGroenewold]

At around 27:00 you're mentioning how it makes sense for the manufacturer. I do have to disagree there slightly. Back in the day, these things/kits were all about figuring it out for yourself. A kid learned a ton from that, these days I only seem to see these kind of products that are just about bringing some components together like a jigsaw puzzle and then by magic it works. There's no learning in that I think. Other than that I love this and your other videos a ton! :)

[@NicolaiSyvertsen]

Sure taking something that doesn't work and making it work can teach you a lot but I don't see why all products should arrive in that state. You can still play around with Arduino code and the components on your own even though it arrives in a ready to run sort of fashion. There is always the choice of buying the Arduino board, servos and other misc components separately.

*Summary* This video focuses on controlling an Elegoo Smart Robot Car Kit 3.0+ using a custom C++ application powered by the ASIO library and the olc::PixelGameEngine. *1. Introduction and Robot Car Showcase (**0:00**)* * Recap of a previous video controlling a robotic arm and introducing the concept of hardware programming. (0:00) * Unveiling the Elegoo Smart Robot Car Kit 3.0+, acknowledging its sponsorship for this video. (0:51) * Unboxing the kit and showing the components: Arduino board, sensors, motors, chassis, etc. (2:03) * Demonstration of the pre-programmed robot using the infrared remote: forward/backward movement, turning. (7:01) * Testing the obstacle avoidance mode (using the ultrasonic sensor), observing its limitations. (8:14) * Overview of the official mobile app for Bluetooth control, but the goal of this video is to build a custom PC application for that purpose. (9:39) *2. Analyzing the Pre-existing Bluetooth Program (**10:13**)* * Looking at Elegoo's provided code examples and tutorials, specifically "Lesson 2: Bluetooth Car". (10:25) * Examining the provided Arduino code (11:16): * Motor control using Pulse Width Modulation (PWM). (11:22) * Basic functions for forward, left, right, and backward movement. * Simple communication protocol using UART (Universal Asynchronous Receiver/Transmitter) at a baud rate of 9600. (12:13) * The code listens for single-character commands ('F', 'B', 'L', 'R', 'S' for forward, backward, etc.). (12:38) *3. Building the Control Interface with PixelGameEngine (**13:12**)* * Creating a `sButton` structure to represent clickable buttons in the application. (13:35) * Adding `Clicked()` function to `sButton` for detecting clicks. (13:48) * Adding a `DrawSelf()` function to allow buttons to draw themselves, including text (centered) and borders. (13:53) * Utilizing the `olc::PixelGameEngine::DrawStringProportional` function for visually pleasing text rendering (new feature demonstration). (14:37) * Instantiating and positioning four buttons: forward, backward, left, right. (15:21) *4. Setting Up ASIO for Serial Communication (**16:22**)* * Linking ASIO and defining preprocessor macros to avoid warnings. (16:25) * Creating an ASIO `io_context` object (`ioContext`) (16:59) and a `unique_ptr` to a `serial_port` (`port`) (17:05) for managing communication. * Handling serial port creation and configuration: * Instantiating `port`, specifying "COM3" (determined based on device manager). (18:03) * Setting port options using `set_option`: * Baud Rate: 9600 (matching the Arduino program) (18:45) * Character Size (8 data bits), Stop Bits (1), Parity (none), Flow Control (none) - standard UART 8N1 protocol (19:11). *5. Asynchronous Reading with ASIO (**20:11**)* * Creates the function `AsyncReadFromPort()` (20:28) to asynchronously read single bytes from the serial port: * Utilizes `serial_port::async_read_some()` (20:41) with a one-byte buffer (to process individual characters). * Lambda function (provided to `async_read_some()`) prints received bytes and then re-primes the `io_context` by calling `AsyncReadFromPort()` again, creating a continuous reading loop. * Calls `AsyncReadFromPort()` initially in `OnUserCreate()` to initiate the asynchronous reading process (21:50), and starts the `io_context` thread (21:55). * `OnUserDestroy()`: Includes logic to: * `cancel()` the serial port. (22:40) * `close()` the serial port (22:46), wait for the ASIO thread to finish (22:59), and only then safely reset the `port` pointer. (23:28) *6. Testing Communication with a Bluetooth Terminal App (**23:35**)* * Demonstrates communication between the PC application and a mobile phone acting as a Bluetooth UART terminal: sending and receiving text. (23:53) *7. Adding Functionality for Writing to the Car (**24:32**)* * Checks for mouse button presses and whether a button (`sButton`) is clicked. (24:38) * Uses `port->write_some` to send single-character commands to the car when buttons are pressed: 'F', 'B', 'L', 'R' (25:09) * Sends 'S' (stop) when the mouse button is released (25:37), making button presses momentary actions. *8. Replacing the Bluetooth Module and Testing Car Control (26:33) * * Explains the Elegoo module's limitations - it's hardwired to work with only their phone app. (26:33) * Switches to a more generic Bluetooth module (previously used for the robotic arm project). * Demonstrates successful car control: forwards, backwards, left, and right (using the PC app to send commands and observing real-time responses). *9. Future Possibilities and Outro (**29:03**)* * Briefly explores exciting future possibilities, such as incorporating sensor readings, line following, more complex control mechanisms, and potential for letting viewers on Twitch control the car. * Thanks Elegoo and encourages viewers to consider purchasing the car, providing a discount link in the description. *Key Takeaways:* * The video demonstrates a real-world use case for ASIO to control hardware wirelessly via Bluetooth using serial communication. * By analyzing existing code examples, it's often possible to figure out protocols and adapt existing implementations. * Designing classes that encapsulate their logic (`sButton::DrawSelf()`) makes larger projects more manageable. * Understanding the importance of properly managing asynchronous operations (canceling, waiting, and resetting) is crucial for preventing potential errors, especially in hardware control applications. i used gemini 1.5 pro to summarize the youtube transcript
