2 questions: what size copper tape do you use? 1/4 inch or 1/2 inch? Also do i have to fold the tape on the edge or can i just cut it and connect a new piece of copper tape to go in a different direction? ...i having trying this at home an can only get one led to light up at a time...any ideas what the problem is?
I helped my young son make a robot birthday card for his mother. The robot’s eyes light up (the LEDs) and instead of copper tape we used conductive paint. It was super clever and an amazing lesson! 🫡
Very useful video - thank you so much for posting. Can the LEDs be any length or does it have to be a specific length? I don't know what to order for my school.
You did a great job explaining how to make a paper circuit. Your directions were clear, and your explaination was accurate and helpful.
i m also a tiger
I will be using this in my class. Thank you
Do you have a copy of your paper template that you can share?
Yes! Is this a free printable, by chance!? So good!
What if I use 2 coin batteries and doesn’t work?

Why don't you need a resistor to regulate the current? Won't it burn up the LED? Doing this for my class!
Long term use will burn the led. But it's better to use a capacitor
1 question. Does the adhesive side of the tape conduct too??
It does, but not as well as the non-sticky side. Just make sure you press the tape down hard to form the connections
Does it matter if the adhesive side is making contact with the non-adhesive side? Are both sides conductive when they make contact?
I tried doing that with the conductive tape... you just need to make sure you really press it down hard
Yes both sides are conductive
Hi, is it possible to light up 4 LED using 3V battery?
Very useful video - thank you so much for posting. Can the LEDs be any length or does it have to be a specific length? I don't know what to order for my school.
You can use any length because you can join them to the circuit using the copper tape.
This is great! Does it have to be the 2032 battery? Or can we use a different battery?
It doesn't have to be a specific type of batteries. I used a coin battery so it fits nicely in the card.
Quite unique 🥼 reminds me of children toy name electronic a box full of experiments (good job sharing this )
do you have a tutorial for multiple ones
You can add more components in series in each loop
@vt.physics I'm having a problem I followed this and there's only 1 led light opening I'm using 3v nattery
I have a problem because im using the same battery and its not lighting up multiple lights only 1
Can we replace the copper wire in place of copper tape?
Ues, certainly! I just wanted to tape the circuit to the card so that the pupils can keep them afterwards.
Why is mine only 1 led light
Wow😮
Qual a tensao da bateria??
Any coin battery would do. I think I used 3V
thank you teacher for this sharing
You save my life 💞
Awsome
Can we use other tapes
they have to conduct :)
why do you sound 12?
cause he maybe 12
im using 3v
i lover you so much jinx '
