Binary Decade Counter
February 18, 2026 • EPISODE 298
How do integrated circuits actually work? In this episode of Science LIVE with Roger Billings, explore the fundamentals of integrated circuits with a closer look at a binary decade counter and how it processes and counts electrical signals.
Learn more about the Acellus Robot Dance Contest and Acellus World, coming to Kansas City in May 2026! And get ready to discover fascinating science in the natural world—from hydrophobic spiders that repel water to the surprising fact that rainbows include invisible colors beyond what our eyes can see.

Hello from SC!!!! Excited for new video
Hi from IL.
Hello from NC!
Dr. Billings, you have struck gold with the Protégés. Thank you for sharing their brilliance with us!
This was a really fun science live!
Very cool!
hi i’m from delaware
Looking forward to next Wednesday
issac from MD
Excited for my first show!
The robot ACD2 was very cool. I like that it was blue and the dance movements it made. I also liked how William Hershel’s discovery from Newton’s prism about the colors had different temperatures.
How were you able to do that in less that ten minutes
Coding is really fun I’m glad to be learning more about it.
This is cool
hi from Indianapolis
Hi from ky
hello from Michigan!
science live inspires me week!!
Hello all! Here from VA!
I Love Science Live So Much ❤❤❤
the robot was pretty cool might need to build my own
this is really cool!
Hello from missouri! I love anything abt coding, super cool!
Charles from Texas
That’s really fascinating.
I like the ACD2 Robot singing and dancing, this Robot is so cool!
It is!
Thank you for always putting so much effort into these awesome science lives!
I love science live
I liked how the protege’s explained binary. They made it really simple and easy to understand.
I love social emotional.
Hello from bc I enjoyed this live
loved this live!
Hello from Maryland!
love the robot
Hello from Colorado!
Love science live
Been enjoying the Science LIVE so far!
hi from texas huston
Is it possible for a 555 integrated circuit to overcharge and if so what happens?
Hope everyone had a good week and good job on it
Hi! I’m from MS!
Hi from Colombia, I like how to the robot dances to the rhythm of the music!
Hihi from Florida!!!!!
I like the song that the robot dance to.
The dancing robot was my favorite thing tonight on the science live.
I never knew about any of these until tonight they are very cool
hello from NJ!
I love ac-d2 awww awwww awwwww awwww
finally wendnesday that means science live I think this is the best live so far
Hello from Arizona! Great episode!
hello from texas amazing live
Would this new technology really be more efficient than windmills?
Science is so cool.
Hello from Arkansas!!
hello from the big TN
how big is the flip flop
this is so cool and its very interesting
not Caleb trying not to crack up the entire time
i love science live!
Hi, Samia from Texas!
If a flip flop turns things on and off, is that where we got the name for flip flops? Because we slide them on and off?
I love science live <3 :3
How many different types of integrated circuits exist?
Hi from HT!
This is such a cool concept!!
I like the part about the infrared light
Never even thought about looking up what translates binary code into language we can understand. The 7 segment driver.
I’m glad I got to learn more on circuits with the proteges, I look forward to what they have next, everyone did an amazing job as well! Great Live!
I’m so excited for the Robot Contest!
I love social emotional.
Hi from Ga!!
Hi live science live and all of this stuff is so interesting
I see the seven segment display on my alarm clock.
Love science live !
Hello from MD!
I love learning about circuits.
the 7 segment driver translates
Hello, from Illinois. Ac-D2 is really cool.
Soo cool watching from Georgia
Hello from Md
What is the power .vs. the ground?
The robot dancing was soooo cool
Hi from Colorado. Learning about circuits was interesting!!
hi from texas/
hello from tennessee
Hey! I used a 7 segment display in my coding class last week.
Hello from OH!
Comment here if your graduating in may at Acellus IST
i learned smth new today, and that was the flip flop!
Hello from Ohio.
Why do they call it a Flip Flop and not an On Off?
Watching from SC! Love Science Live!!
The dance and song was so nice that the robot did!
always wondered how my gadgets worked, now i know
The water spider is so cool, I had no clue any animal could do that.
hello from Louisiana!
What does a flip flop circuit do?
hi from texas
Caleb is so funny😆
Looking forward to acellus world!
I LOVE THESE SEGMENTS!!!
The dancing was so cool! Most entertaining thing I’ve seen today.
The dual flip flip is interesting to learn about
I like how they are making it seem like a boxing fight
Sorry for being late I have pc issues But im here.
HI, from Iowa
Happy to be here
i love that little robot dance it was so funny
hi from illinois
I can’t wait until acellus world becomes accessible online!
amazing! Wild how a small circuit has real tiny transistors in it
I love coding!!!!!!!!!
from texas
Hello from The Bahamas!!!!!!!
Hello from Texas
I LIKE SCIENCE LIVE and robots
You should put the bigger version of the robot on the Acellus store.
It’s nice seeing all this, after graduating the Acellus coding classes.
Jackson from Illinois hello
I think it’s cool how inferred works and I’m so excited for the science fair
Hi science live!
I never knew about the scientists that were talked about today! Thank you for teaching me some information about them!
This flip flop video is interesting!
Hello from Hawaii
Are there any spiders that are fully aquatic or is that impossible?
hi from Arkansas
Hello science buddies!
Looking forward to a new video! Koa
The proteges are back at it again! They do a really good job teaching new things.
Binary is so cool!
The robot is so cool!!
Loved the robot dancing.
hello everyone ! hope valentines was fun for you guys
I love how the robot was dancing and singing music at the same time
Flip Flop!
How do you make those flip plops that say ground
The proteges do a nice job of explaining hard to grasp topics.
The dancing robot was so cool was my favorite part about this live!!!
Great live as always!
Why does a computer use 1 and 0
hey from texas
binary code is so interesting
hey hey from texas
Why is the sky blue?
Hello!! From Texas
hi from texas
What is a decade counter?
Hi from NC!
hi from Montana
I love science live!!
What would happen if the thing that you’re building you got one wrong.
I always enjoy when Pajet Monet is here
How do I find out more about the dance competition?
My first question is where would the gyroscope that would farm wave energy be in the ocean? Near shore, in the middle of the ocean, or in bays? Second, would this technology replace wind mills?
Watching from Illinois. Thanks for another great Science Live
Hello From Maryland !
Back with my favorite show
Science is so cool, I hope we learn more and more as years pass on.
Hi I am from grand prairie
The Protégés are so hilarious 😂!
Hey guys! I just started this program! I love it! Way better than the one I used to use
The decade counter – (David)
This is great educational episode. Thank you
Love the episode! Hello from a Arizona
hi from california
Hi, from South Carolina, love the robot!
That’s crazy. Hi from Louisiana
Hello from Missouri!!
hello science live 🤗
Wow, today’s live was so interesting. I hope that we discuss similar topics next week.
i love science live
Wow! I was wondering how numbers were communicated through binary. Are there other ways to use a circuit other than the mainstream ways like a control panel or radio?
the robot dancing was so cool
Hello everybody, I recently started my ASL class and it’s amazing. I definitely recommend it for anyone who likes learning new languages 🙂
Hello Ms. Monet and Mr. B, I would like to ask if a pen-like erase would be a suitable option for my project for the science fair. A eraser pen is an eraser shaped as a pen, and this eraser can erase ANYTHING (pen, marker, lint) that type of stuff. My question is, will this project be worth my time (ps answer on live so I know!!!!!) Ty
Love Lynzie cloud.
P.s- I am such a huge fan, and Ms,Pajet Monet is my favorite teacher!!!!!!
thats such a great idea
Go DrB! Love from California!
This science live is so good
I like robot dancing
Are circuits used to power phones?
Hiii from Texas
This is cool!
Hey from ID
This is so fun!
