Hi! It only speaks English as far as I know

And what can I use to make it portable

hey there! It depends on the servos you're using. The MG995 servos can have current at maximum load: 1200mA according to components101.com/motors/mg995-servo-motor You want enough current to accommodate all 15 servos. Current load for 15 servos could be around 18A (15 * 1200mA = 18000mA = 18A) It's advisable to choose a battery with a higher current rating than you need to ensure reliable and stable performance, taking into account factors like battery efficiency, voltage drops, and safety margins. Be sure to do our research and make sure you look over data sheets for the servos and other components you're going to use. I, personally, haven't used more than 6 servos on this driver. If you're using 15 MG995, I'd be interested in what you think of the performance. 👍

Hey there! thanks. Here is a video where I set up Bottango, the software I used for the servo movements and the LED light turning on and off. th-cam.com/video/DWvVfzULl6U/w-d-xo.html Here's a video where I add a motion activated mp3 player. In this video I got rid of the servo driver board. The animation runs fine without it. th-cam.com/video/E8tsB2GdYjQ/w-d-xo.html I hope that helps! 👍

Hey! I'm glad you found the video useful. I still have this little drone and it's still a lot of fun to play around with. I just wish the battery lasted longer. Thank you for leaving a message, I do appreciate it it 👍

hey there! Sketches are save as main.py. By default, the OpenMV Cam executes main.py automatically if it's in its root directory when powered on. Can you share your code? I'll do my best to help out 👍

Hi! I'm happy to help however I can. Feel free to ask here or email ( bmonsterlaboratory@gmail.com), or Facebook (facebook.com/profile.php?id=100059867144068)

hey there! Yes, this servo can change rotation in increments of 5 degrees. The MG995 can rotate 120 deg, -60degrees to +60degrees. here's a link to the data sheet - www.electronicoscaldas.com/datasheet/MG995_Tower-Pro.pdf There are servos that rotate 180degrees and continuous rotation. 👍

Hey there! Ya, it could be....It could be a number of things. I used these kits to practice soldering because they are very cheap. As a beginner at soldering, I used too much solder and applied too much heat to the contact which is ultimately why it failed...if I had to guess. But, you only getter better from practice :)

it's funny stuff! 👍🎵

interesting. do you get any error messages? Where is the exact point of failure? I can make a TH-cam short on how I do it...if that helps.

It doesn’t say any error messages I just don’t let me export it from bottango to Arduino

@@Sammyrobotics-bv1x Hmm... I'm not sure what the problem could be. In the animate tab on the left, look right and click export to code under the animations. From there you just follow the prompts and select a folder. I'll keep playing around with it but I haven't seen a problem so far.

I was able to open a brand new project and go straight to export. It says I have no motors or effectors in selected animation clips. make sure project is saved and try again. If it doesn't work, remove and reinstall Bottango....

Hey there! I found a good spring that wasn't too stiff and wasn't too loose. The wire would snap after a few adjustments but the spring that's in there now is great! I guess if anything is placed in the head, like a board or speaker, we'd need a stiffer spring. But as of now, it's working well. It's also light enough that I can use 5v to power the servos without any trouble. I tried everything on this head animation. Went front redneck hardware quick fixes to recommended parts. It was fun. ready for another one!

Good catch! 👍

Hey there, thanks! The LED on/off switch is controlled by Bottango while the pattern, blink speed, and color are controlled by the mini controller on the LED wire. It was easier for me to change the look of the LEDs whenever I want without connecting the board and changing code or bottango settings. I used Bottango to control the serovs and power to the LED, the motion sensor and mp3's are controlled by Arduino. I may not have been clear about that (oops). A curve may work, I'll have to try it. I have another one to build. I would like to make a controller for it, use xbee or maybe some cheaper bluetooth modules. We'll see. I think it will be fun to come back to this every once in a while with some different builds.. Thanks for leaving a comment. Much appreciated !! 👍

@@BMonsterLaboratory no, you were clear in the explanation, and the reasoning makes perfect sense. Happy to comment, helps create community and supports each other’s work.

The Droid Division and Bottango groups are great to talk to. They both have a great community of users that are always helpful.

it's not very powerful. I don't recall what the power requirements were. you might be better off using a mini dc motor with a small propeller on it. 👍

Hi! Code is straight from the stepper.h library. I show you how to load it to your board in the video. There is also a diagram in the video. 👍

Hey there! I went simple with the LED ring. You can put your own LED code in the Arduino sketch but this WS2812B LED ring comes with a mini RGB controller, and that is what I use. I can control blink speed, color, and pattern by pressing 3 buttons. All I do for the LED ring is provide 5v power...It's the easiest way. I am posting one more video with this pit droid head motion this weekend. It will have a basic HC-SR501 motion sensor to to activate motion. I will be including the code I added to he exported sketch and a number of diagrams in case someone else wants to do the same thing. If you would rather have a bush button, that's doable too. The goal is to post the video Saturday morning ....10 or 11 am EST.

Hi Sammy, I'm on a pc, so I could tell you how I did it for pc....not sure how it translates to mac. Export from the Bottango software, open the file and drag 2 files (GeneratedCommandStreams.cpp, GeneratedCommandStreams.h) to the Bottango Arduino driver folder. From this file, open the Bottango Arduino sketch, go to BottangoArduinoConfig.h tab and uncomment #define USE_COMMAND_STREAM line. If you are using the servo driver board, uncomment the #define USE_ADAFRUIT_PWM_LIBRARY line. I am currently using 2 servos and not using the servo breakout board and it's working fine. If you're not using the driver board, leave the line as it is "// #define USE_ADAFRUIT_PWM_LIBRARY " From here you should be able to upload and start your animation without the computer. Upload the file from Arduino IDE. If you connect back to the computer, be sure to comment the command stream line "//#define USE_COMMAND_STREAM" 👍

Thanks! lots more I plan to do with it 👍

Hello, and thank you for the compliment! I have several videos using this Sparkfun mp3 player shield. I have a video that matches your description right here - th-cam.com/video/zamlAniU2nQ/w-d-xo.html You can find the Arduino sketch for that video on our Facebook page by searching "mp3uino" on Facebook, just check the comment section. If you have any questions about changing the code or adding something that's not included, feel free to ask. Have fun and thanks for reaching out! 👍

thanks! great to hear from you 👍

hey there! here's the video th-cam.com/video/Gj5QA3xu8fI/w-d-xo.html 👍

hi, yes... you should be able to. sorry for the late response. If you're using the code I posted on Facebook, you would have something similar to this: for (int pos = SERVO_MIN; pos <= SERVO_MAX; pos += 1) { for (int i = 0; i < NUM_SERVOS; i++) { if (i % 2 == 0) { // Even servos pwm.setPWM(servoPins[i], 0, pos); } else { // Odd servos move - opposite direction pwm.setPWM(servoPins[i], 0, SERVO_MAX + SERVO_MIN - pos); } }

hmmm.... interesting! I switched to solder paste. no more liquid flux for me.

hmmm....interesting! I switched from liquid flux to solder paste. works great~

hey there! The flux on the pins and sd card would have made it difficult to use. I didn't power the board on before I cleaned it. I thought there may be a good chance the flux could interfere with electrical contacts. It's great at what it does but it can be very messy, especially if you spill it 😆

Awesome! La Crosse weather stations are great. Thank you for leaving a message. I hope you enjoy yours, too. Very convenient to have one. 👍

That's good to know! It sounds like you would have to work with smaller amounts. I imagine it's pretty harsh, may need to crack a window when you use it.

hey there! Sorry to hear that. They used to have good customer service but it's been a long time since I reached out to them. Maybe you need a firmware update? Try that and see if it works. fingers crossed!~

hey there! It looks like maybe you don't have the Adafruit motor library installed (AFMotor.h). Install the library by going to Sketch > Include Library > Manage Libraries in the Arduino IDE. In the Library Manager, type "Adafruit_Motor_Shield_librrary". You should be able to install from the IDE, which is convenient! Hope that helps 👍

Thank you! I appreciate that

Спасибо! Эта доска действительно доставляет массу удовольствия 😎

do you have a continuous rotation servo ?

Thanks! I honestly thought I was going to have to throw it away. Glad I kept it. 👍

@@BMonsterLaboratory that’s awesome that it worked and great to share so we can all learn

@@SummersideDiver isopropyl alcohol works great!

You could also put a coffee filter on your pcb, pour a small amount of IPA on it and then rub on the filter with your toothbrush. I don’t recall who taught me this but it works great. You can also use bio ethanol which is a smaller molecule and cleans even better. Using the same toothbrush to brush your teeth however is not recommended 😅.

@johanbenko7818 I like the idea with the coffee filter. It's lint free, unlike my paper towel and q-tip! I would never use my personal toothbrush to clean electronics...gross. However, I don't like to waste coffee filters. Suppose I could reuse the filter for my next pot of coffee if I let it air dry on the table? 🤣

Hello! If the 5v 15A supply is working for you, stick with it. You want to be sure to have plenty of overhead current to handle the servos when they are all drawing the most current at 5v and the motors will only draw the current they need. Check data sheets and test to ensure there's no over heating or erratic behavior of the motors based on your project. But, I would keep the 5v 15A supply for 6 servos. I hope this helps!

Download the MAX7219 library. There's an example in the library called MD_MAX72xx_HW_Mapper - open this example in ArduinoIDE. Upload the sketch to your boad with the 8x8 led connected and follow directions on the serial monitor. It will ask questions about direction of led movement....after you answer the questions it will tell you what yo have. The type depends on how the matrix is wired and arranged which affects how you address them in the code. I found that most of my 8x8 modules are FC16_HW

@@BMonsterLaboratory thanks!

@@fredericknielsen4984 you're welcome. best of luck to you!

hey there! you can add 2 variables, "step" and delayTime" in this example. delayTime determines the pause length between each movement (smaller delay = faster movement) and step determines will determine how smooth the motor will move. You can play around with both variables. Try this: #include <Servo.h> Servo servoMotor; const int servoPin = 3; const int targetAngle = 90; // Target position for the servo void setup() { Serial.begin(9600); servoMotor.attach(servoPin); servoMotor.write(0); // Start at 0 degrees int pos = 0; int step = 1; // Step size of 1 degree per movement int delayTime = 15; // Fixed delay time in milliseconds if (targetAngle > pos) { for (pos = 0; pos <= targetAngle; pos += step) { servoMotor.write(pos); delay(delayTime); } } else { for (pos = 0; pos >= targetAngle; pos -= step) { servoMotor.write(pos); delay(delayTime); } } } void loop() { int targetAngle = 90; // Target position for the servo int pos = servoMotor.read(); // Read current position of the servo int delayTime = 15; // Fixed delay time in milliseconds int step = pos < targetAngle ? 1 : -1; // Determine step direction based on current position while (pos != targetAngle) { pos += step; // Increment or decrement the position servoMotor.write(pos); // Move the servo to the new position delay(delayTime); // Wait to maintain a consistent speed } // Optional delay to handle behavior at the end of movement delay(1000); // Wait for 1 second before next move or action }

hey there! Would each file go through a different animation ? For example, button 1 would make it talk and look up, button 2 would make his light blink, and button 3 would make it look around while talking and flashing lights. Am I on the right track here? You can do that...or should be able to do that. Can you explain a bit about what you want to achieve? thanks for the comment and good luck with your animations! 👍💪

I have 3 different motion profile (2 servos and 5 on/off events ) I would like to assign 3 buttons for each motions .. hope u get it and thanks for quick replay

I haven't done anything like that yet. It sounds doable though.

I appreciate your reply.. can I least connect one switch to play one motion profile

Hey there! I have been making a lot of motion sensor projects lately but I don't have one with Bluetooth. That's not to say we can't make one with a video to go along with it..that's no problem. My favorite mp3 player board is the sparkfun mp3 player shield for arduino uno. When one Arduino with a motion sensor catches any movement, it sends a signal over Bluetooth to another Arduino. That one's hooked up to a SparkFun MP3 Player Shield and starts playing music. They should be able to communicate up to 30ft away in an open area with the HC-05 and HC-06 modules. Or, if you want to keep it simple, just use one Arduino Uno. Attach the MP3 Player Shield, hook up the motion sensor and a speaker directly to it, and you're done. No Bluetooth, no worrying about signal interference, it just plays a music track when motion is detected. This video is similar to this description and can be wireless to operate on it's own. th-cam.com/video/zamlAniU2nQ/w-d-xo.html Happy to help wherever I can. Thanks for reaching out 👍

Hey there! Thanks for the question. The short answer is yes, you can use this over the phone. The easiest way to do it is speak into the audio hacker microphone and place the speaker close to your phone so they hear a distorted voice. It's really easy to use over your computer. I have used it in zoom meetings and video games online. If you have a way to speak on the phone through your computer, that would be a really good way to do it.... a voice of IP or some integrated phone network. You would basically connect this audio hacker between your amplified microphone and the pc.
