Using SD Cards with Arduino - Record Servo Motor Movements

[@lesrstoxsal1764]

Dear DroneBot, You are definitely one of the great explainators on youtube ! Cause: 1. You just don't constantly whirling around with the cursor on de screen. 2. You just don't play any strange music in the background. 3. You articularly perfect and extremely effective. 4. You take the time to explain everything accurately. > You are the absolute best, so keep on going strong !!!

[@spencoid1]

yes!!! thanks for no crappy music!!!

[@venkatyalamati3285]

Yes....

The world needs more people like you, very, very good job explaining, thank you, and hope to see more from you. Best regards.

[@spencoid1]

most technical youtubers just don't get that we (or at least I) want information not entertainment, thanks for such a clear no BS presentation

[@KikiTay]

You are incredibly generous to share your skill and knowledge to the world. The amount of work and effort you put into making it so simple to understand is incredible! I learnt a lot! Thanks for doing this, I'm extremely grateful!

[@daiseman]

The clearest, most consistent and useful Arduino content on KZbin. I'm hooked. Keep up the great work.

[@fenylmecc6347]

Your videos are the best and easiest to understand

[@davidbelchamber6102]

As with everyone else, thank you for the outstanding videos. I’ve finished building the mechanical aspects of a 4 servo CNC 3D wire, rod and tube bending machine. I’m about to add a number of optical interrupter limit switches, a touchscreen lcd control panel and an SD card reader. My knowledge of C++ is growing daily and the software design is underway. None of this would or could have happened without your videos. Profound thanks.

[@paulbertrand8935]

This channel is a 10.5 out of 10 - always incredibly helpful and well produced. I'd kill for you to do a similar video about playing back audio with SD cards

I wish I had found you when I started thinkering with the SD cards....it would have made my learning a lot easier. Great Video!!! thank you for sharing.

[@asrajo5728]

Thank you very much sir, your explanation is very easy to understand, I like that you process using the library that is already in the Arduino IDE. Unlike others using their library which makes the tutorial confusing. I hope you are always healthy and your business smoothly, thanks. Looking forward for your another tutorial

[@phanxquang]

For anyone having trouble with the CS pin... The CS (Chip Select) is also commonly referred to as SS (Slave Select). So, if your have a board and can't find the CS pin in the pinout, try looking for SS instead.

[@venkatyalamati3285]

Thank you so much for the clean explanation ☺️

[@croissantossus]

Thank you for the very detailed explanation

[@erikw8644]

Thank you!! I love your channel and subcribed. I'm a computer programmer, interrested in building my own hardware. You very well explain how to do this. I am sometimes struggling with why to add like other parts beside just the board and the addons, like resistance between led (not the case in this video). I guess thats beyond the scope of the videos and perfectly okay. I had an arduino starter kit already laying around, but didnt know how to get started. I have now ordered some extra parts and soon going to try to make my own plant watering system by measuring the soil moist. Love your vids. Thanks and I'll keep watching! 😎👍

Your videos are such pieces of education! Can't believe how much I've learned in an evening and how easy and entertaining that was. As a follow up to this video, how can I make a file browser to select the file I want to read on the SD card? Thanks for all 🙏

[@TheUnofficialMaker]

really cool, great details and explanation.

[@akshayjose6555]

This video is gold for me

[@douglasheld]

DroneBot Workshop, 21:30 why do you use such a slow serial speed of 9600 baud? Are there RF problems turning up the serial speed to more usable levels?

[@PatnaikUC]

Excellent. Can you extend it to 16 servos using Arduino servo shield 2+16 or the SD card with one joystick to record the position of each servo and play automatically thereafter

[@vivekagarwal117]

Thanks , your information is very good. Why analog port integer data is converted to string to store in SD card ?

[@camcompco]

To add to what others have already said . . .thank you for sharing your obvious wealth of knowledge in such a clear and cohesive way. Question, how would you introduce a feature to playback the servo motion in the same speed you recorded it, including pauses, etc . . . . Thank you for any assistance with this. All the best, John

[@simonbancroft8579]

Superb tutorial, as usual. Thank you.

[@Alex-eu6kn]

Nice explanaition. I did similar things. Worte a python app on Linux connected a PS4 Controller via BT and records the data on the PC and visualize the JoystickPositions. By developing that I noticed that it is important to write a timer for each dataset (mean per array row). Keep in mind that the microcontroller may cannot read and proceed the data in realtime. If you plan for example sound synchronised animatronics you need to have a timer based data structure. Otherwise it will go thru faster or lower than you planned.

[@botak333]

Hi sir, how to record and play more than 1 servo sir??.

[@mehmetgul8686]

[@stuartron29]

Thank you for all that you do, truly excellent

[@jflow_07]

at 12:56 it was mentioned that 10k potentiometers were used and any value from 5k upwards would suffice. Why is this? Can I use 1k or 2k pots? Thank you.

[@tuannguyen-vy2kz]

Very easy to understand ❤❤

[@azyfloof]

Ok I had NO idea these parsed actual file structures on the SD card! I just thought you could write/read raw data, and that was it. This makes these MUCH more attractive for future projects! :O Now I'm imagining my projects with Neopixels, but reading colour swatch/pattern data off of an SD card instead of from the firmware. This'll make it easier to upgrade/change colours and patterns :D

[@weetzinng2217]

Thank you so much for the detail explanation. keep up the good work

[@DigvijaySinghRathore]

Can I replace the potentiometers with joystick with the same code ?

[@rajkunwar1454]

How to access these data in the SD file from the PC? What kind of interface it requires?

Dear sir your video is too good and great explain in video really i like it. this all are very useful thanks for this videos. i subscribed your channel sir hats off........................sir

[@magmagth4346]

thank you very much dear Bill I'm beginner in Arduino so i need help to use push button instead of potentiometer, and instead of servo motor i want to use relay 5v. so this is mean i want to use digital data instead of analog , many thanks

[@bobbihansel]

Fantastic tutorial, thank you!

[@startobytes]

Hi could you make it with you about the nrf24l01 Module and how to Connect it with the Arduino Uno?!

[@mog99lie]

Greetings from Germany and thank you for the video. I have just finished my 6 axis arm and looking for a Ardunio program to control it and only came across your channel this evening. You have asked for suggestions for more videos?? I have two. First, what about a push button switch for start and finish points for the servo to record the location, that would save a lot of memory and perhaps the S card would not be needed? If using multi servos it would also enable every servo to go to the final position directly. My second request (If not already requited) is a guide around your workshop, looking around your shop you are well organise, I wish I was!! I can do simple programming with the Aruino and learning all the time, it is great but I will be 70 very soon so I want to run before I can walk!!! Ha Ha!!

[@luberies]

Marvelous explained! Thank you!

[@gaets04]

I want to make music come out using what you just demonstrated with two servos when I apply a momentary switch to move the servo one way and then the other way after pressing it again.

[@siamtourist]

Great work! Thank you for sharing

[@jihunmin5130]

SIR, THANKS FOR YOUR CONTRIBUTION FOR ARDUINO LEARNERS AS WE AE NOVICES IN THIS FIELD AND WANT TOUNDERSTAND THE POWER OF FUNCTIONING ARDUINO AND RELATED PROJECTS

[@YamamotoGenryusaiShigekuni]

There is no reference on Arduino website to "buffer" function or "toInt". Is there any library that I can find some information about such functions?

[@tonyt8587]

Hi Another great video. Q. How Doug you control end of file when writing data in the never ending loop? Does SD close the file properly when you shutdown the Arduino? How do you know that the last record is written? Thanks.

[@RalphWLundvall]

I have that question- how to end gracefully. I think a test of a button press would be one way to create False to end a while True loop.

[@douglas2lee929]

Can anybody answer this question for me. I assume the answer is very simple. I am just hardly even a beginner, so please forgive the "ignorance" of my question. Here it is: What controls the "frequency" or the "timing" of how fast (how often) the three measurements are written to the memory card? Is this a function of the 9600 baud rate? Or is it controlled or determined by something else? I'm referring to the three measurements from the the potentiometers, during appx time of 17:05 through 17:38 of the video. Is there some kind of "throttling" someplace along the chain that determines this "write rate"? Is there some command in the code that determines it? It appeared that the data was being written to memory quite fast. Using the exact same set-up that he is using here, how would I change the "write" speed to say, half as fast, or twice as fast? Meaning taking a measurement only half as frequently as it is happening here. Is the real world rate of data writing to the memory card a function of how fast the hardware can "grab" the values at the analog inputs, or in some other manner? Thank You to anybody who has the time and the knowledge to answer. If this was covered in the video, I missed it.

[@pantac4493]

Can this be used for setting different variables that it reads from the txt file? (I could change blinking rate of led, pin numbers, etc.) all from variables on sd card? Thanks

[@Wajiduddaim]

3:24 if its 32 Gega Byte, 2 Tera Byte and 128 Tera Byte than you should Use Capital "B" because the small "b" stands for "bit"

[@117MCHALO]

I am doing a mechatornics project and was wondering if you could write to the Micro SD card reader that are found in LCD displays and use it as a Data logger aswell as a standalone display

[@MrHics]

24:00 why did you link the ground circuits together?

[@azyfloof]

The signal from the Arduino to the servo needs a ground reference

[@lewishamilton9941]

I have a project which requires reading data ONLY from a SD card into a static array in the setup(). I only require this to run start-up. This uses a total of four digital pins on the Arduino which I would like to re-use later in the sketch for different functions. Is this possible?

[@srikanth5832]

Sir, can you explain how to interface SD Card and nRF24L01 together. Thank you.

[@watchingin3d549]

Yes bro. I got all these awhile ago and nmwould like to know. I want to send gcode to machines via sd card or the nrf. Either use sd card when no internet or use nrf when around wifi.

[@AngryRamboShow]

@@watchingin3d549 Look on the channel "Teaching Tech," he's got a instructional about connecting online to a 3d printer via raspberry pi's, which have built in wifi and blutooth and also ethernet ports.

[@AngryRamboShow]

28:20 You see in this setup function that we're reading from a .txt file named "servopos.txt" stored on the SD card; then in a while loop we read it string by string into "buffer." buffer = datafile.readStringUntil(' '); _and_ myservo.write(buffer.toInt()); So buffer is a String that you dump a file into at runtime and then can convert to Integers. Those Integers can then be passed the same way data is passed via the nRF24L01 video. That's the magic part, the reading and writing from the SD card; those subfunctions that you see in those final examples give you the option of passing data in and out of a stored state to use whenever. How you use them is entirely up to you.

[@HelloThere-ph3zb]

You're doing a great job in your tutorials. I will forward your site to others that want to learn, especially women that want to learn code. I also love your "BLUE" shop color scheme. Was that your concept or a interior decorator? What city/country are you in? Thanks, Best Wishes

[@Mau365PP]

You are amazing ! One question, how can I create multiple files with different recordings in each file? For example, each file cound be a recording for a robot to do, and by playing different files at a time I could have a robot do one activity at a time. Thanks

[@glennhair7954]

Does the map command effectively replace the need for slope and point math calculations for translation of the servo position? If this is the case, is it accurate?
