I’d love to see an Arduino in the Acellus Shop!
The chatgpt giving you 2 different answers scared me I need to do more research😭but the plant counting numbers was so interesting and smart!! Never knew plants could be intelligent! Looking forward the next live :]
Please, please, please add a microcontroller to the Gold store. Also where can we get the GoldKey plug in? I’ve looked everywhere but can’t find where to purchase.
I agree that we need an Acellus Computer Board in the store. It could be called Acelboard?
I love all those inventions that the kids made with all the sensors
Love from Connecticut!!!
When you said that the Arduino Uno runs at 16 megahertz, did you mean the memory, or any other specific component?
Acellus is the best!!!
Favorite time of the week is watching these lives.
Hello from South Carolina!
wow we could make many cool things using the microcontroller.
Hi from Virginia!!!!!
excited for the hydrogen car!
I agree with adding the microcontroller thing to the acells gold shop.
I look forward to Science live every Wednesday.
Learning about touch me not plants was pretty cool.
You can name it BB for Billings Board.
How long did it take for Massimo Banzi to create The Arduino? Also, yes, we should put one in the Gold store!
I liked the r51 part of this weeks video!
Its great learning about a technology thought leader and innovator, as he draws from his diverse range of life experiences, inspiring students of all ages to love science and to understand the value of education in empowering their life missions.
Hey Roger Billings could you make a science live about biofuel and compare it to hydrogen as a fuel source.
WE LOVE ACELLUS!!
Count me in!
Acellus is so much fun
I loved this live and can’t wait till the next one. Thank you for making them.
Learning about inventioneering was so cool

i hope you do to!?!?!
I never heard of the Touch-Me-Not plant. I think they’re really cool. I wonder where they grow, where they are native to.
the proteges today was funny
Plants are so amazing!
Name it the Acellus board! I love science live. I think you should add the Arduino. Why does AI give different answers?
I enjoyed this weeks science live.
I enjoy watching these each week. It’s always so fascinating at the new things we learn.
Yes 👍 we should totally have a microcontroller in the Acellus Gold Store!
i am so happy i joined this program it has taught me so much
your science lives are amazing thank you !!!!!
Plants are so interesting!
The Touch me Not plant is interesting! If plants are learning on a cellular level, who is to say they aren’t smart?
It would be amazing if Dr. John could broadcast from San Francisco.
Great science live today can’t wait for the next!
I thought that the video was interesting.
Why have we only just now just descovered that plants can count
I love science live so much, I can’t wait to watch this episode!
hey everyone!! how was everybody’s day been so far?
I liked the Legos
Yess, do it!! I will love to hear about it, even if I can’t come!
I think the circuit board should be named “The Billboard 51”
the protégés Lego battle was so funny 😆
Love the Inventioneering Club, they are very fun playing with legos
I think that having a micro controller in the store is a great idea.
Hello hello! From Alabama!
I like r51 🙂

I can’t wait to visit the Acellus campus. It is an awesome place. Acellus World is going to be a great time to visit this year.
I thought it was really cool when they talked about the plants and how when you touch them they would curl up to protect themselves.
The science live was wonderful!
This is so awesome the brains in these people that allowed them to make Acellus is crazy!
I love Science Live. It makes me was to do some the the things that’s you guys do.

I am so excited to get a shirt from the store with my points soon.
In this video I learned about Massimo Banzi.
I loved the r 51
Acellus rocks! Thanks for another great (and hilarious) episode! I have an idea – could Acellus have classes in Anatomy for human and animal sciences? I love vet med and I am taking Medical Terminology currently to expose myself to medical terms, but it would be amazing to have veterinary classes!!!!!
I LOVE ACELLUS🌷🌷🌷🌷🌷
Thank you Dr Billings.
how does the plant know when it needs to get ready for the sunlight?
Great episode! See you next week.
Microcontrollers look like small motherboards
Happy anniversary for the hydrogen car too
Hello from Utah I really enjoyed this episode!
I am probably going to watch Acellus world live this year.
Yes, I would like to see an ‘arduino’ in the shop with also instruction videos of things we can build to get started.
The robot claw demonstration with the castles was really fun! Keep it up, Acellus!
Thank you Dr. Billings!
Entertaining as always!
I think that would be a great idea adding a micro controller to the gold store!!
this is a great community
How do the plants count? How did R-51 walk away and the lights turned off and walked back and the lights turned back on?
I like how to study with Acellus. Motivates me to have better study habits and also excited for new classes.
It was so cool when they played with the Claw.
Hello from Tennessee
I think the tickle me plant is really cool
This science live was great!
I enjoyed learning about the Arduino board
I have been on a roller coaster once, it was really fun!
