I enjoy the PROTEGES a lot!
Funny how arduino got its name lol!
Haha that Lego scene was hilarious!
Hey from West Virginia. Awesome episode. Thank you.
The Arduino is revolutionary.
Claudia definitely deserved to win!
Great job exploring how microcontrollers work! You showed creativity in building your project and followed instructions carefully. Keep experimenting and trying new ideas!
I love watch Science Live so much!!
The plant that reacts when you touch it is really cool, and it can kinda count and track time is fascinating!
Good Morning from Minnesota!
Hello Dr. Billings, have you ever seen a don’t touch me plant?
I like that your team use humour in your videos, it makes learning fun. Life is to serious to not have fun. Good work making a control switch with the Arduino
I love these!!! There so cool about how everything works!!
I love acellus!! signing in from alaska🙂↕️
Hello from California!!! I enjoyed this live
I just wanted to say that I think the touch-me-not plant is special because it shows how plants can sense danger and respond quickly, which makes it very fascinating.
holy cow! the the things that people can do with arduino’s are actually so mindblowing
Let’s do it! Acellus is the absolute best!!!
Hi From New York
Hello teachers, will Patrick Mera be at Acellus world? Than k you, teachers!
Tobias should be giving Italian class! C’mon lets get an Italian course!
Acellus is the best!
I love watching R51
Hello Teachers, how many days will the next Acellus World last?
Hello from IL love science live
I always look forward to these sciences lives!!
I hope more and more students join acellus academy
Inventioneering is such a neat thing in my opinion
Dr. Roger Billings is the best !!!!!!!!!!!!
i like r-51
I have always wanted to try inventioneering but I’m not sure how to.
R51 is so funny!
Hello from Bangladesh
acellus is better than real life schools
Hello from Japan! Thank you, Dr Roger billings!
Hey from Texas ! This weeks science live was really great and fun, can’t wait for the next one.
Happy anniversary to the hydrogen car, and what a day for fishing!
It’s fascinating that microcontrollers can operate so many smart devices such as an whole entire robot!
Congratulations on the 60th anniversary of the hydrogen car, and thank you for another great episode. I enjoyed the story of how the Arduino got its name.
Thank you so much for another Marvelous episode, Chat GPT study got me think again about AI and its implications!
It’s interesting that this year is the 60th anniversary of the hydrogen car
Acellus is the bestttttt!!!!!!!!!!!!!!!
Watching from Colorado! Awesome live!
Khloe watching from Mississippi.
Science live makes me love everything
Hello from Japan
I want to be like you when I grow up!
I really appreciate it! It means a lot to me, and I’m grateful for your kindness and support.
I am now very intrigued by the touch me not plant!
Acellus has taught me so much!! i look forward to the Science Live Nights every week
The pulvinus plant is cool. The arduino could be helpful.
To be able to see a hydrogen car over at the Acellus headquarters would amazingly awesome
I hope they put that in the shop
Science live is so fun. Hello from Texas.
I love Acellus!!
Dr. John with Technology Spotlight is my favorite part of Science Live! I hope he can broadcast next week!
I liked the part about the leaf that protects its self. It’s interesting how plants can understand something like protecting its self. Can’t wait for next week.
The Mimosa pudica (tickling plant) kinda reminds me of a Venus flytrap. Interesting video this week.
Hello from New Jerseyyy!!
Comment Acellus has been a blessing! love Acellus
Plants can count! The Mimosa plant counts and the Arabidopsis Thaliana plant can do math. I thought the same thing, that a plant without a central nervous system or a brain knows how to respond to light and can be studied. Amazing! How do plants know how to come back even after the harshest winter? I also learned about the endless possibilities of the Arduiono, and how unselfish it was for Massimo Banzi to share it with all.
Dr B that experiment was amazing and you always know how to make us laugh.
Who is the most influential inventor?
It’s a shame I won’t be able to see the hydrogen demonstration in person, but I will definitely tune in online if possible!
so much information and education is provided in every Science Live episode, hard to sum it up in a comment. Brilliant work and witty commentary
Acellus has helped me learn so many things. Thank you for the live! I love watching them, keep it up!
Acellus is fun!
Happy 60th anniversary to the hydrogen car!
Hello from North Dakota
Hi from Bangkok!
Seeing the iconic hydrogen car in Acellus headquarters would be absolutely incredible along with an entire tour of the Acellus building having a look at all the classrooms and everything.
Massimo Banzi is an inspiration because he has not only made technology easier to use, but he has also inspired a new generation to study science, technology, engineering, and math.
thank you for enspiring me every week to be my best!!
Hey Dr. Billings, how old is R-51?
Dr Roger is the best!
I gotta remember this joke : Rabbits are good at maths because they are very quick at multiplying! Thank you Doctor John!
Hello everybody! This is Santi from Oregon.
I liked when they used the robot arm knocking down the towers
Always look forward to these!!!!
it would be so cool to see the hydrogen car!
Love this video thanks for everything!
Wow, that plant thing is crazy, imagine if we had robots that used similar technology to simulate feeling. Go DrB
It was cool learning about the Arduino, got some thoughts on what I could make with it!!
It could be called the Ace Board, Dr. B Board, or the RB Board
Hello from Missouri!!!
Hello from Texas!
Thank you for making these for us!
It is amazing how water osmosis within the plant can cause such an incredible reaction.
I loved learning about Massimo Banzi
Acellus better than any school !!
Thank you dr.b this uplifted my life thank you dr.b loved this video.
r 51 is the best, he makes these videos more than amazing
I found it so interesting how R51 and the microprocessor were used to control movement and light, it made me think about how technology can be used to create things that respond to their environment like robots or even flying devices!
I just started to use Snap Circuits, and I hope that in the future I can use the Arduino for making my life easier.
The Arduino device looks way too cool to not get.
The plant that responds to touch is cool. I think it is amazing how they can sense time. The inventioneers and Claudia I like because of their funny towers. I like the proteges because they smashed down their crafts.
Hi from VietNam
I think that you should put the Ardindo in the Acellus store.
This is a spectacular live!
That’s cool how the plant closes when touched.
Acellus is my favorite way of learning I recommend it to everyone I know
Acellus has honestly taught me more then in person school ever has so thank you for that
this science live was my favorite one so far!
I LOVE THE SCIENCE LIVE!!
I love science live, its so fun watching it every week
Hello! I think, for a name for the microcontroller, we should choose “Scikik” (pronounced as Psychic).
Reasoning behind it : Science Kit – Sci-Kit – Scikik!
The hydrogen car sounds awesome!
i love this program
This was another amazingly educational and informative science live! I can’t wait for next weeks.
I love looking forward to watching science live every Wednesday
i like these coding lessons they do
Howdy, from Texas!!
Hi from mississippi
That one plant is like a Venus fly trap.
Any type of circuit is so intresting to me.
Thank you for this episode of Science Live! The Protege video was funny, thank you!
Love Acellus!!
That is amazing that he visited The White House for Mathematics Excellent
Science live is the best of the best
Hiii from Alabama
Gotta do more science lives about the hydrogen car. Been interested in cars lately🤔
A plant counting is really cool!😃😃
So excited to watch Science live again.
Great Science live tonight! Looking forward the seeing the hydrogen car!
I genuinely enjoyed watching this Acellus Live session. The lesson was engaging explained all of the topics, which made it easy to follow and understand. In conclusion, it was a valuable learning experience that I enjoyed.
Howdy from Texas!
Science live episodes are always so entertaining and interesting!
How did people discover how plants move when they are touched?
It is genuinely Amazing, learning about How that specific kind of plant learned when and when not to move\open up on specific days. It makes me wonder what other kinds of plants can adapt to either different weathers, lightings and things along those lines. This was an amazing live, looking forward to the next
Hello from WI!
Mannn this is soo awesome, science live is amazing!!!
i will join the science fair if i can.
It’s amazing to see that plants may be able to count!
I Will definitely go to Acellus live!!!!!!
We enjoyed this!
Hello from Indiana! 3rd science live since I joined the program, love them so far.
I liked the roller coaster when it was upside down!
Hey, I really enjoyed learning about the tickle me plant.
What other components would you need to build a board?
Congratulations on your upcoming anniversary of your Hydrogen car! Can’t wait for the celebration at Acellus World! How exciting!
Really like R51 ❤️
Oooooh the 555 is impressive, also as a project can we make ANYTHING dance or bulid our own robot? Also big fan you guys are awesome!
I think the plant knowing how to count is very impressive.
This is the best part of my week.
The new course sounds interesting!!
These guys are cool!
Can’t wait for next weeks video!!!!
Loved the lesson thank you!
Got sick couldn’t attend the live but got to come back and watch

How do you troubleshoot common problems when working with microcontrollers
This episode was very interesting! Thank you all. Also, I have a pretty random question. What made Dr. Billings want to start doing the r-51 segment?
I love watching science live videos!
We Love Acellus!!!!!
i enjoy these videos so much!!!
Acellus is great!!
I saw the hydrogen car last year at headquarters when we went for my brother’s graduation.
Is there an electronic system we can create to turn garbage into new materials or use it to grow the ecosystem?
Nice live!!! And how do people study plants so in depth?!
Hii from Texas! I loved this video!
I really enjoyed this live especially the r-51 part it brings back memories of my grandad thank you for this live.
helloo from New York very fun live today
