So smart and talented plus absolutely gorgeous ❤
agreed!
You are the best 🎉🎉
Thanks! 🤩
This is great! Watching now. you and hackmakemod are my favorite channels!
Thanks for watching! Let me know if you'd like to see a specific topic covered!
I've just found your channel. It's fantastic. Thank you for leaving the mistakes in.❤❤❤
I'm glad you found the channel! I learn the most from my mistakes 🤣
I love to tinker, so I bought one of those arduino project kits for my son and I to have fun with. It was such a pita to figure out. As a result, it's been collecting dust. You're really taking the mystery out of all of it, and I'm dusting it off and seeing what I can come up with right now. I'm so glad I stumbled across your channel. Thank you!
This is awesome, I am actually working on an animatronic that can use this. I'm just starting out on Arduino so this is very helpful!
Let me know how your animatronic project comes along! I'm doing an entire series on the PIR sensor to control servos, motors and even mp3 players!
Thanks for explaining things in an easy to understand way. I look forward to the rest of this series.
Glad you enjoyed it! I'll be covering how to control servos, motors, and mp3 players soon!
Have you ever used ESP32? With ESPNow?
Wow! So cool! The world is coming aliiiiiiivvvveee
Love the info and how you explain. Simple for me to understand. I’d also like to see how to make random blinking eyes on a prop/mask animatronic. I’ve seen it on instagram but no clear explanation on how they did it on a mask. Thank you 🙏
That's a great idea for a future tutorial! For the mask project, one thing you may want to check out is flickering LEDs. They come in red, green, yellow and a variety of different colors. No coding is needed. You just include a resistor and power them with a battery and they flicker randomly on their own. Of course you can program specific patterns with Arduino and trigger them with a PIR sensor too!
@@RachelDeBarrosLive that’s a cool idea too with blinking LeD’s! But to be more specific; sorry if I wasn’t clear 🙏: blinking eye lids where it looks like the character is shutting and opening eyes. I saw someone build it with a resin printed helmet shell to wear. Which I wonder how they stuck such small components to do that. Thank you so much again!
Love your attitude. And the way you presented the material. Keep up the good work.
I've got several Arduinos and haven't taken the time to learn to program them. I think this might get me doing it. I like this video format. No intimidation.
Great video. I have been having trouble with my PIR sensor. Either the LED stays on too long or off too long. I try some of your code to see what went wrong.
I tried your code and it works better than anyone elses code. Great job.
One thing though in your 3rd example, the one using the led, you forgot to setup the ledPin as OUTPUT. Not a big deal really, easy to fix, but I thought you might want to know.
How that's awsome vid it sounds cool if only I new how to code 🤘🏽😃🤘🏽
The world's best Queen teacher thanks
Rachel, have you ever used hall effect sensors to control a dc motor for movement of a prop to a specific location?
High! Hello, there! Hopefully, all is well! Love you intrest in electronics probably vary technical! Goodluck with all those components!
Awesome presentation style. Informative and engaging way to do these tutorials. Thanks
Glad you like them!
This stream is reminding me I have an acrylic protected motion detector porch light to finish!
😂😂🤣😢😢😭😭😭
Noooo - not more projects!!! 🤣
@@RachelDeBarrosLive - Yaaasss! I'll finish one of my many projects someday!
🤣😂🤣😂
Hello. I was looking to purchase some of those motion sensors for smart home applications. In the description it says the manufacturer did not install a photodiode. A different one (but looks exactly the same) says photoresistor. Are they the same thing? How will i know if i need to install one? What are the necessary connections for integration?
Great to see that I'm not the only one who does that cringe thing when the sketch is compiling. I'm all "no whammies, no whammies" every single time.
Can Arduino simulate keyboard presses? Say I want it to press Crtl+Alt+Delete when the PIR detects motion, is there a command for that?
Just found your Chanel. It's Great! I'm curious, why aren't you using the latest Arduino IDE(2.3.2)?
The computer I live stream from isn't the one I usually use for coding so the IDE is waaay outdated. It's on my to-do list to update it so hopefully you'll see the latest one in future videos 👍
Gorgeous and Geeky! LOVE LOVE LOVE !!!!
you like to tinker and build things any chance you might build game camera and also maybe have it with wifi ability
your stunning . and great informative videos. 😄😍
Please teach me, or help me I have a lot of projects that need some help from experts like you.
Is there a way for the Motion Sensor / Arduino to play a mp3 file when it detects motion.
It just so happens that I'm about to release another video on just that in about a week or 2! 🥳
INTRUDER ALERT! Owld Skew
lol kekeke. perhaps next step would be to switch to an ESP so u can go wireless.
to start off, the most basic example would be to have the LED follow the inverse of the PIR GPIO. i.e. (pseudocode incoming) digitalWrite(ledPin, ~digitalRead(PIRPin)). That's because the PIR sensors will hold the line high for, what, a second or something, which is long enough to for an eyeball to see the LED, and you don't run into any of your issues. Less is more sometimes.
second, you should just avoid delays. use rollover safe millis() math instead. Basically almost any time you use delay(), you're probably doing something wrong. This is an unfortunate deficiency in the Arduino ecosystem -- no notion of a "scheduler".
But basically once you structure the code that way, it's easier to start doing stuff like your fade and other events.
