Maybe take a look at the YEP 20A HV SBEC hobbyking.com/en_us/yep-20a-hv-2-12s-sbec-w-selectable-voltage-output.html?srsltid=AfmBOopTK4U0PTWRLhwaJf2Umhg3uVD9vOON1yzLjkN3PkIJhk46rfO1 This would give you plenty of current capacity (20 A), supports a 2S LiPo input (6 V-8.4 V) with no problem, and offers multiple selectable output voltages (5 V, 5.5 V, 6 V, 7 V, or 9 V). Some things to keep in mind: Use a 1000 µF on the servo rail to smooth out current spikes. Reduce voltage drop by keeping wires short. Use the right gauge wires for your setup, for both sides - battery-to-BEC and BEC to the servos. I don't want to say you should buy anything specific, but this might help you in doing some research in finding the right one. 👍

Sorry to hear that! I'm not sure if there's a manufacture warranty- I haven't had any problems yet. Are your points of contact clean? Just a thought. Best of luck to you and Merry Christmas!

Hey there! Yes, you should be able to use Arduino cloud to operate any of these servos from their web interface - from anywhere. I would like to do a few more videos with this breakout board. Thank you for the excellent question! 👍

Hi! thank you. You can easily power the Arduino and servos from a single power source by splitting the 12V supply. Here are a couple of ways to do it: *Connect the 12V power source to a terminal block, and then split the output. One connection can go to the Arduino, and the other to the buck converter where voltage can be reduced for the servos. *Alternatively, you can use mini quick terminal connectors (lever wire connectors) to split the 12V supply. From there, route one connection to the Arduino and another to the buck converter. For the Arduino, it's recommended to use: *7-12V for an Arduino R3 via the VIN (+) and GND (-) pins or the barrel jack for convenience. *Higher voltage if using an Arduino R4, as it supports a broader input range. I also like to use the Sparkfun RedBoard for Arduino projects like this. Their barrel connector can handle 7-15v and the board itself is a good price and good quality. No matter what board you use, just follow the recommended power specs. When splitting power, make sure that your power supply provides enough current for all connected devices. I try to provide a power source with at least 20% more current capacity than my project requires to avoid overheating or instability. I hope this was helpful~ Merry Christmas & Happy New Year!

Yes, you can rotate the display by remapping the matrix's X and Y coordinates. I thought about splitting the 7 bands, with one set on the left and one on the right, taking advantage of the increased matrix height. This setup would give more distinct amplitude levels and might even look better visually. 👍

@ I agree, I think it would look better. Nice work, cool chip. Ever try using the sound reactive fork of the WLED software?

I just looked up the WLED project - very cool! There is lots of info on that site. I haven't seen this before but I'm going to check it out. Thanks for letting me know

@ Have fun! 👍👍

Hey there! No, a hobby-grade servo does not retain offset or centering adjustments once you remove the controlling signal. These servos are basically "dumb" actuators that rely entirely on PWM signal they receive to determine position. They don’t have memory or calibration storage that would allow them to remember a new zero point once you disconnect them. I beleve there are some high-end servos that you can program, but I don't have any. What you can do is set the servo arm manually. You can manually remove the servo arm and reattach it so that it points straight ahead at the desired command. This ensures that when that same "neutral" signal is applied in the future, the servo arm will be aligned as you set it. You can also setup a feedback System with encoders to restore the position you want. The servos I generally use are MG995, which does not have internal non-volatile memory. This means it cannot retain any position settings or offsets once it loses power or is disconnected from the Arduino.

Yes, you should be able to. I haven't tried it that way yet. 👍

switching the potentiometer with your RC receiver output probably will not work as intended, because the two signals are different types of inputs. Taking the three wires from where the potentiometer was (V+, GND, and the analog output) and just hook them to the receiver’s servo channel (signal, V+, GND), the Arduino’s analog input will not read a stable voltage. It would see a quick changing pulse. Attempting to read this directly as an analog input won’t give reliable results. The Arduino’s analogRead() is designed for steady DC voltages, not digital pulses. you’ll need to modify your Arduino code to read the pulse width of the RC signal. Once you interpret that pulse width as a control value, you should be able to drive your stepper motor.

@@BMonsterLaboratory Ok I'll keep searching, Thanks for taking the time to reply

@@NevesProjects you're welcome. I hope it works well for you! 👍

hey there! Thanks for the feedback, I appreciate it. I have never repurposed speakers from and old TV into a newer TV, but I can tell you how I would start. In your current TV: When you take it apart, look for the built-in amplifier and it's power rating. If the TV doesn’t have a strong enough amplifier (common in cheap TVs), the speakers will sound weak, even if they are good-quality speakers. If this is the case, you should buy a better external amplifier. Even a small Class D amplifier can drive better speakers efficiently. Follow the wires from the speakers and find where they are soldered and/or plugged in to help you get an idea of what a replacement should look like. Observe how much space you are goin to have for your new speakers. Will the new speakers fit in the old space? My Samsung speakers were fairly low profile and the space was tight, making it difficult for many speakers to fit i that spot. You can mount the new speakers externally and even use your own amplifier for the new speakers if needed. You will also want to check the specs on the speakers for impedance in ohms and wattage. You want this to match so your new speakers don't damage the tv's amplifier. In the discarded TV: Check these speaker specs (Ohms and wattage). Most tv speakers are going to be around 4-8ohm, just make sure they are compatible with your current tv amplifier. Are the speakers in the discarded tv connected the same way they are in the current tv? This could determine how easily they can be integrated. As for the speakers, check for loose parts, cracks, or tears in the cones that indicate damage. And of course, a soundbar may be an easier option....but where's the fun in that? 😁 This isn't an absolute tutorial on what you should do, but I think it will get you started. I'm sure you'll do your own research along the way, which I encourage. There are numbers and specs on the back of most speakers, type these into google and try to locate a datasheet to give you more info. Good luck to you!

@@BMonsterLaboratory thanks a lot for the detailed guidance. I will follow your words. Definitely there is no fun plugging in a sound bar. Unless the sound bar is broken and I fix it, before I plug it. 😀😊

hey there! Try going to Tools > Board > NodeMCU 1.0 (ESP-12E Module) or whatever board you're using. Try goin to preferences in IDE and adding "arduino.esp8266.com/stable/package_esp8266com_index.json" to board URLs. in Arduino IDE go to preferences>Additional boards manager URLs: arduino.esp8266.com/stable/package_esp8266com_index.json make sure you have the CH340 driver installed. There are good instructions on how to do this at Sparkfun website - here-->learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all I just got 2 of my esp8266 boards out and they work fine with the code that was posted on Facebook. Of course, don't forget to add your network credentials in the code. 👍

hey there! These little soldering kits are for learning and they are very easy to mess up, so you did great! The pcb is very thin, cheap and easy to ruin with a soldering iron. if you want nice solder contact, remember to clean your tip frequently and use some solder paste. I love solder paste because it helps solder flow over the metal contacts evenly. I might get another Christmas tree and try again this year! 👍

@@BMonsterLaboratory I bought a second one, but before soldering I'd like to see on a breadboard if I can use different components to make it blink a bit slower.

@@Thomas_A_H slower blinking would like better.👍

@@BMonsterLaboratory I've just checked: The main portion of blinking doesn't come from the capacitors and transistors (they just seem to oscillate the voltage at the LEDs a bit), but from the LEDs itself. If I connect a LED to a 4.5V power supply with various resistors in series (lowest I've tried is 330Ω and I the LED fully lights up with values up to 10kΩ or maybe even more), the blinking speed and color (within certain ranges, when the resistor is too high, certain colors no longer appear) isn't dependent on the resistor value, but changes over time due to circuitry inside the LED. 😐 The full circuit still works at much lower voltages though, up to a point where there is only an oscillating dim red glow 🙂

hey there! Here's what I'm thinking. Is this what you want to do? The code controls a servo motor based on whether a laser is hitting a photoresistor. When a laser is pointed at the photoresistor, the photoresistor value exceeds a specific threshold. As a result, the servo motor moves to a new position. When the laser is not pointed at the LDR, the servo motor returns to its initial position. The PCA9685 servo driver is used to control the servo, which allows for multiple servos to be connected if needed. If i'm wrong, let me know. Sounds interesting!

@BMonsterLaboratory the problem I'm running into is the threshold. Idk how m3asure it or Calibrate it or whatever if so new to this but I ha e developed a HUGE passion in the recent weeks and I'm on a mission lol no retreat no surrender, learn this thing Inside and out and create some wild ish

@BMonsterLaboratory yes

@@danielrizzi1153 I have a XINGYHENG 175pcs 7Values 5mm Photoresistor (LDR) kit that I bought on Amazon about 5yrs ago. There are multiple values i this LDR kit. If you want to set up multiple targets, just pick one value and set the threshold values in your code. For instance, in this kit I would use only the GL5506 LDR for consistent calibration and uniform behavior. This LDR has a dark resistance between 2-6k ohm and a light resistance of 0.15M ohm. For a good threshold value, the resistance will be relatively high wihtout a laser 500-800 depending on the voltage and will drop significantly with a laser (200-400 range). The exact analog values will depend on the strength of your laser - you can see the values in real-time by watching the serial monitor. Use a voltage divider circuit toconnect the LDR to the analog pin on the Arduino. One end goes to 5v while the other end is connected to a 10k ohm resistor (to ground) - and the point between the resistor and LDR is connected to the analog input. You can search google images for LDR voltage divider circuit. For you code, you may need to add something like this if you're using, for example, 3 LDR's. The threshold in this example is set at 500.

hi there! You should not use a 3.7v battery to power your nano 33 IoT board. Arduino boards with a VIN pin are designed to use a voltage regulator to step down to the board's operating voltage (3.3V in this case). The regulator typically requires a few volts above 3.3V to regulate properly, which is why a minimum of 6V should be used for stable operation. A 7-9v battery would probably be the best for most projects. I would go with a 7.4v 2600mah battery for something like you see in this video - small size, good capacity, and rechargeable! Here's a link to the data sheet where you can look up power specs for the board docs.arduino.cc/resources/datasheets/ABX00027-datasheet.pdf I hope that helps!

ya, me too! It's a bit catchy 👍

for this video I am using a breadboard power supply to totally power the motor. I don't run motors or LED strands through Arduino. I think max current on this breadboard power supply is 700-1amp, will have to double check. but ya, the motor is powered from the breadboard to prevent current from destroying the Arduino.

Yes, that's a good idea. I have a IMAYCC 0-24V Adjustable Power Supply. It does an excellent job of supply enough power for multiple projects. Split the various converters and your problem is solved. If you get a buck convert, be sure to get one rated above the current you need. They typically operate at 85-90% efficiency. I like to leave 20% headroom for current so I don't overheat. I hope that helps 👍

You can user 8 servos on this. are they they same model? MG995? I see recommendations not to use more than 10amps with this board. If your motors pull more than 10A, use an external power supply for the motors and ensure common ground with the PCA9685. This will help protect your components, and the board will control the motors properly using the data pins without overloading its power capabilities. 👍💪

hey there! you should be able to do this on any Arduino. A few things to consider: You may have to change your code as far as pin mapping goes. Always check the power and current tolerances on the board you're using. 👍👍

Hi, thanks! You don't have to use arrays. You can define individual constants like this: const int SERVO_1 = 0; const int SERVO_2 = 1; const int SERVO_3 = 2; ...etc. But you'll need to reference each servo individually in your code. Doing it this way makes iterating over multiple servos or performing actions on all servos cumbersome. Arrays make your code look cleaner and easier to manage. NUM_SERVOS defines the number of servos you are going to control. It helps you easily adjust the number of servos without needing to change the code in multiple places. good questions! 👍

@BMonsterLaboratory thanks, much appreciated.

maybe 5-7amps - I didn't check it with a multimeter. Just guessed based on datasheets. 5 servos motors are MG995 and they have a max current of 1.2-1.5A. The servo that closes the clamp is MG996 which can draw up to 2.5amp. I'm using 5volts for all the motors. If all motors were under max load at the same time it would pull 9amps, maybe. I considered that my absolute max. I like to have max current supply 20% higher than I would ever need so wires and motors don't get hot. I don't operate all the servos at the same time and I don't run them at max load so...maybe 5-7amps at the most. I'm sure I could have used a 10amp without any issues but my 15amp converter was convenient. 👍

Are you referring to the exported files? There are 3 files that export from the software, a text file, a GeneratedCommandstreams.cpp file, and a GeneratedCommandSrtream.h file. You need to put the .ccp and .h files in your Arduino folder. These files should be in the same folder as your .ino file. when you open the .ino file you'll see the GeneratedCommandstreams.cpp and GeneratedCommandSrtream.h tabs included in your Arduino IDE program code. remember to uncomment code lines as necessary on the BottangoArduinoConfig.h tab. I can send you screen shots if this is hard to follow.

Yes please send me a screenshot please

But how are u going to send me a screenshot

@hyperplayeryt8426 facebook. Email.. you pick

I dont have a Facebook email

Awesome! Mine are still going strong as well. 👍💪

It was part of the Elegoo Mega tutorial you can download on their site. You will need to have the LiqidCrystal.h library in your Arduino file. Here's the code I used: //www.elegoo.com //2016.12.9 /* LiquidCrystal Library - Hello World Demonstrates the use a 16x2 LCD display. The LiquidCrystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This sketch prints "Hello World!" to the LCD and shows the time. The circuit: * LCD RS pin to digital pin 7 * LCD Enable pin to digital pin 8 * LCD D4 pin to digital pin 9 * LCD D5 pin to digital pin 10 * LCD D6 pin to digital pin 11 * LCD D7 pin to digital pin 12 * LCD R/W pin to ground * LCD VSS pin to ground * LCD VCC pin to 5V * 10K resistor: * ends to +5V and ground * wiper to LCD VO pin (pin 3) Library originally added 18 Apr 2008 by David A. Mellis library modified 5 Jul 2009 by Limor Fried (www.ladyada.net) example added 9 Jul 2009 by Tom Igoe modified 22 Nov 2010 by Tom Igoe This example code is in the public domain. www.arduino.cc/en/Tutorial/LiquidCrystal */ // include the library code: #include <LiquidCrystal.h> // initialize the library with the numbers of the interface pins LiquidCrystal lcd(7, 8, 9, 10, 11, 12); void setup() { // set up the LCD's number of columns and rows: lcd.begin(16, 2); // Print a message to the LCD. lcd.print("Hello, World!"); } void loop() { // set the cursor to column 0, line 1 // (note: line 1 is the second row, since counting begins with 0): lcd.setCursor(0, 1); // print the number of seconds since reset: lcd.print(millis() / 1000); }

If you need any help, just ask...nuttin' worse than bad info. But honestly, after you put this together and get it to work once you will probably use I2C or Qwiic connect displays in the future. All these wires for this display are cumbersome and get in the way of everything else.

@BMonsterLaboratory thanks to you, i made some progress, but the display just shows 165:165:165 15/165/20165

@@BMonsterLaboratory ill try the original code you first posted

@@notbuyingit8047 ya, give it a shot. make sure all the connections are correct and it should work fine.

Thanks for checking it out! I'm glad you found it helpful! 👍

@@BMonsterLaboratory it's ok bro

Hello bro, your video is very good. I don't know if you can make a video where you use the PCA 9685 module in bottango. Maybe in case an Arduino code is needed so that it later works in bottango and about the storage of the animations that are made in bottango because I think which has a very low limit and I would like at least a 3 minute animation to be saved​@@BMonsterLaboratory

Hi, thank you. I could revisit bottango but it may be a while. Did you check out this video where I used the PCA9685 module ? th-cam.com/video/DWvVfzULl6U/w-d-xo.html

Plsss can u tell me

the AFMotor library is missing from your Arduino libraries. Same with the NewPing library. You need them both in your file before you can load the sketch to your board. 👍

You need the libraries in your Arduino file. see previous answer

I agree. it is a bit expensive but I've had fun with it for sure. I would like to try out some other options.

Thank you for posting this! I hope it was helpful 💪👍
