This is a PIRfect example of embedded programming! 🎉🎉 I always learn something new when watching you!! Plus I never get bored 'cuz you have so much fun energy !! I can hardly wait for the next stage of the talking unigoyal !! 😊

[@VinodKumar-kw4kn]

I really appreciate you made it easy to understand , programme codes and its execution. Beginners can learn easily.

[@utahwaxwing]

I really appreciate how you clarify so much and make it fun

[@raysimon1368]

First time seeing one of your videos i can build just about anything i want to but when it comes to driving it with a motor thats when things get complicated im a machinist certified welder and a fabricator all that i understand but wiring a driver much less writing a code just went over my head just want to thank you for your great teaching skills i will make sure to pay attention to your next video love your upbeat personality and you are as beautiful as you are you are a good teacher thanks for sharing

[@robertmccully2792]

I can actually follow what you’re saying. Not talking over our heads trying to prove how smart you are.😊

[@scaresandsparks]

I really like your videos. You're so natural in front of the camera. Or at least you look it! I will send people to your channel for intro stuff as you explain the basics so well.

[@scubaken89]

Another helpful tutorial explained very well and easy to understand. Can't wait for the next one.

[@Loosatsu]

I need most new things explained step by step like this. This is awesome 🤘

[@RachelDeBarrosLive]

Awesome, thank you! 👍

[@RiDankulous]

This is very interesting, thanks. I have a suggestion for a build and its a sun tracker. I've vaguely recall seeing it done before. One purpose is to find the optimal vertical and horizontal angle to adjust solar panels. If I make an oven heated by a parabolic mirror, the system can find optimal angle for maximum heat. After initial acquisition, it can track periodically and move when needed. It can monitor the temperature with a digital thermometer, and if it's too high then offset just a bit from being directly at the sun, which turns down the heat. And if too low, the reverse. Also, I could set a timer for the cooking time. When complete, the parabolic dish can turn enough away to effectively 'turn off' the oven.

[@berlinjackson1847]

I like your videos. I learn a lot from you.

[@michaegi4717]

I've messed around with those sensors for long time. And I always struggled with false detections... but now I found out that this might only be the calibration phase 🤯

[@user-gk9oj3nb1m]

OMG, Just another brilliant tutorial!

[@JamesCotter-be4se]

This is a great series Thanks

[@mazharkhaliq1971]

Thank you for the video

[@davidanddavidstrading]

New fav channel!

[@robertparenton7470]

Thank You from Frisco, TX.

[@proyectostogo1462]

Great !!! I will make this project next and thank uuuuu love tour cahnnel

[@AJayTheStageArtist]

❤awesome tutorial 👍

[@user-zv3lj1ef7l]

There she is, my favorite influential arduino Teacher.

[@nwvortex]

Would be fun to use this example/code to officiate a game of "Red Light/Green Light," where you have red and green lights tied to the pirState, then introduce a random off time.

[@ControlsEngineerOne]

An other awesome show!

[@lesliefoster9027]

Great, thank you, thank you.

[@dailydoseofnews4828]

Hey Rachel . Would love to see some guide from you based on hoverboards. They are dirt cheap and easy for ppl to get. Comes with motors, batteries and reusable logicboards. For example a RC skateboard or mower ?

[@ZenHulk]

Thank You

[@user-dj9ps3qg8r]

lovely

[@damianbutterworth2434]

Hi Rachel, I made a burglar alarm using a pen laser shining onto a LDR. Works great. Feel free to use the idea. Might be good in America for protecting large area`s. We don`t have large area`s in the UK. :)

[@edparker9837]

I look forward to the "misfit toys" because that is what I plan on making.

[@lgallant2486]

Hi Rachel, what sensor type would you recommend to make a creepy portrait with eyes that follow you? 😮

[@monark175]

love watching your shows. i have a problem with my code. i am trying to get my leds to flash and sweep my servo, i also have leds that are on. my servo doesnt sweep.

[@cadillacescalade5428]

HI, I need this with a IR sensor and sound added In sweep mode.

[@monark175]

also using pir to start sequence. i have simulated smoke, fire, fire station alarms and want to open doors to fire station.

[@cobalt01snet]

Hi Rachel, I have a project a switch that activates a servo form 0 to xxx, with a delay on the xxx position before returning to position 0, can you help

[@ajad4222]

can i ask wht is the servo library

[@anapamelabandoy927]

Hi just want to ask, how can I code when I add a speaker in this set-up. I'm having a hard time adding the speaker to the set-up. It's like when the PI Sensor can detect a motion it will send a trigger for the Servo motor and the speaker to activate. I hope you can help

[@jamiemoles7275]

Need help programming mine ardniuo uno R3 I need a two prong vibration sensor hooked up to it to activate my relay. I do not know how to do that I do not know how to write the program can you please please help me I have tried looking it up. It didn’t do me no good.

[@raulirimes1945]

when im trying to type "Servo scaryServo" idk why mine didnt get orange. Do someone know what i have to do to get it orange or what library i need to have? i use arduino uno

[@cx3268]

How to have the controller to sleep and have the PIR wake it up (interrupt) & do something. This will save a lot of battery.

[@MarioRossibless]

You are espectacular great classes . You're channel is very helpfull. Thank you

[@Jenxqw74]

[@jaguarke069]

Should the pos =0 be 0 respectively? as the ++ -- happens after the check I think you'll end up with 181 and -1 degrees. Is my understanding correct?

[@Sovvyy]

Yes, you would outside the loop as the ++ / - - occurs at the end of each loop iteration. They're using an Int here so the >= 0 condition will be met (unlike with a Byte).

[@jaguarke069]

@@Sovvyy cheers!

[@berlinjackson1847]

Hello Rachel, I am a retired electronic engineer and for a hobby I am learning C++. Are you using a Chromebook with C++. ?

[@RachelDeBarrosLive]

I'm using the Arduino IDE which is free software you can download from their site to program the Arduino microcontrollers. The code is based on C/C++.

[@JyskMaker]

"int" take 2 byte (-32768 to 32767) so if you use Byte 0 to 255 you only use 1 byte.

[@juansantana8448]

why do you always keep referring to inanimate things as "he"?

[@louiepauda6275]

Hey! You know you like electronics! I like electronics what you say maybe I can introduce you to my "Mom"?

[@BrodeySheppard]

Not going to lie, ChatGPT. I just tell it my hardware, some specs on hardware, tell it to "Ask questions if you need to know anything" and tell it what I want. Gives me code that is pretty close first time every time.
