Hello Rachel, I have set up your circuit, but I have problems with the MP3 player circuit. it does not seem to be recognizable. Are you aware of any issue with that chip? I have seen many people complain about that circuit, especially on Arduino R3 and R4, maybe there are some compatibility issues I should look at.... Thanks a tons for your wonderful proposal.

the way u explain sometimes feels magical😁

She is definitely the best at adruino tutorials I've found so far i actually understood what she was doing 😆 lol

This is great learning. But would be better flowing with a board of me own and I wonder if AI can code it for us

Mam do something with hx117 load cell

Very nice explained, thanks

You are a great teacher. You really go through everything and don't assume anyone comes in with prior knowledge. If they do they get a refresher.

Happy New Year Rachel. This was truly in depth. I love it. Thank you. Been watching your channel for a while now. (Subscribed) AND Yes Di Hard IS a Christmas movie. Right up there with Home Alone.

Love the video. I have a question that may be off topic. How would I go about programming different features or options on a small LCD touchscreen display and what software and tools do I need to program it to my needs. Greatly Appreciated

Rachel I have an interesting question, perhaps would love to see a video demonstration if you don't already have one (I didn't see one). I'm learning a lot about my arduino from your videos, THANKS! My question is: I plan to use my arduino to control leds on a costume and for ease of access I want the wires in the costume to have disconnects and stuff. So for a "finalization" of a project do I permanently solder wires to my board ( I have the r3 mega 2560 version with the preattached ports for all the pins) or am I supposed to solder to my jumper wires from a kit I bought and unplug from my board directly? I hope that question made sense. Thanks again for your videos!

Very clear and concise explanation, with just a touch of light heartedness - thanks.

You are a great teacher! Can you show us how to isolate the ground from the case on the exact motor you show here so when you use 2 of these motors you can reverse the + and - on 1 of them without burning something up?

3:28 You can see the flat side when you look at it from the bottom

Can an 8266 board be used in place of the Uno? You talked about the tx/rx of the nano and having to reassign that to get comms to the dfplayer.

ОоОо симпатичная и с мозгами ?! Это очень круто , срочно подписка.

Briefly and succinctly explained excellently without a lot of unnecessary nonsense around it.

THANK YOU I love how easy you explain things. Please do more of this for this kind of projects. I am now working on a 3D printed device that can shuffle cards and serve different players. It should have two DC motors (one for shuffling and the other for serviing and a servo motor to rotate 360 degrees. I haven't found something similar, so I'm going to try it, but I have to start very simple and these videos help me to advance in this project, since I'm completely new with electronics.

I hate it when intelligence has to be dumbed down with over the top, over-emphatic, hyped up 5000 cans of Redbull-fueled voicing. It's so distracting and unnatural that I have to watch you with the sound off and subtitles on. Great job and fantastic information. Thanks.

Can you do a video on how to make things happen in a range? For example I want my sensor to do something between 20-30cm and something else 30-40cm etc Thanks

Rachel, do you have any other videos of your entire garage? Or any other tutorials? I just love it and I'm in the middle of construction on mine, and this exactly what I had in mind! I just love it!

How did you re-upload it

this is awesome

I like this project and this tutorial, good for me

this is the best arduino video ever!

how can I make this smaller and use 3-4 servos?

There’s nothing worse than an unfinished series.

how to connect PS4 Controller to esp32 C3 ?

Rachel you could use a relay in place of your DPDT switch. Then connect the relay coil contacts to power with a SPST switch.

Thank you so, so, so much 🙏 I'm trying to make a miniature chandelier... I understand the Voltage and Resistors... I'm clueless about the Wire Gauge... I know about 18 Gauge for Real Lamps, but not miniature dollhouse LED lights... 😢😢😢 Any help is greatly appreciated 🙏🙏

The GOAT 😔😔🙏🙏

CALL ME A DUMB BUT THE AMOUNT OF CLARITY SHE GIVES THROUGH HER VIDEOS IS IMPRESSIVE AND VERY FEW KZbinRS ACTUALLY GIVES YOU THIS MUCH OF CLARITY....IN TERMS OF HARDWARE AND SOFTWARE.

My pir sensor is not working i don't no what is the issue

A community that costs to join, I'll bet the free ones are 100 times better, they always are. $40 bucks a month just ...for what?

its been years i am trying to write a code and now i am eager to get back at it after seeing your explanation

Just getting into Arduino & stepper motors after getting a 3D printer. Wow this is SO helpful in understanding the code. Beauty and Brains... Thank you. Subscribed.

I just realized I didn't buy a power supply 🥹

You should know I found your channel today, bought a kit today, and was able to follow 3 of your projects...today. Thanks so much. You're great at this!

Hello, thank you for the good explanation. I would like to ask if there is a possibility to add a button that controls changing the lighting pattern.

from where can i get thus code???

Rachel I just found your channel and love it! Someone told me I need to use an Arduino board for a project I'm trying to build but I don't know how to program one to do what I need it to do. I have a 12 volt DC motor I need to make turn on for three seconds and stop for five seconds then turn on in the opposite direction for three seconds and stop. This is for a slingshot auto resetting target I want to build. I would like to know what Arduino board to buy.

Placing the ruler 2 cm from the TX/RX creates a discrepancy between the physically measured and ultrasonic measured distances. The duration between the trigger and echo includes sound traversing that 2 cm gap. Great explanation and example for the modules use. You've given me a couple ideas to consider.

Thank you! I've been struggling with this

I've broken enough electronics components to know that without your clear descriptions for how the different parts of the setup works, I would have been in the dark on this (pun intended). Building up the code from lighting 3 lights to creating rainbow animations was awesome. I couldn't have enjoyed following along more. Thank you!

Merry Christmas Rachel 🤩

Arduino coding is interesting since it combines c++ and JavaScript when it comes to variables. Why would the pins be a constant (const), and the variables not have a declaration like the constants (i.e `var`)?

Rachel has a knack of being able to teach clearly - well done.

This is fantastic!! I have a question. I want to do it where we have a maglock that releases when it's stepped on. Any suggestions?

Is it possible to set the rpm as a decimal rather than a whole number (e.g. 6.61 instead of 7)?

too many technical drawbacks
