PAPERTRONIC CARD - SIMPLE LED CIRCUIT

'Papertronic' is mixture of two word 'Paper' and 'Electronic'. This S.T.E.M. Activity is helpful for learner to understand electronic science by doing it. Here I have made simple circuit on paper that function same as PCB.

From my personal experience what normal theoretical education do is force children to imagine or understand experience that he/she never had. Reason I love S.T.E.M. education is because it tries first to create hands-on experience for learner so he/she can be later able to associate it with theory.

Given Instruction and Design is of Simple LED circuit. Facilitator can here help children in making first later then create curiosity on How? What? happening.

Given material on image is only material we needed for this activity.

Apart from it you need to take printout of given design on A4 paper before you start.

This is Design I made using "Inkscape" - Opensource Vector Designing Software

But don't bother if you never have used this software.

Final Design is in PDF file that is attached here...

I made very colourful design, but Colour print is costly, so I took B&W print.

If you have no budget constraint, then definitely go with colour print it look attractive.

another, issue I face was explaining how to print given file to printing person...

Finally, he won, and I told to not think too much and just print each page on new paper.

According to my design you have to take single-sided print of first page which have bugs clipart and double-sided print of remining two. Here you have to take care of Top and Bottom alignment. I made marking to help but if still difficult then take each print on separate page and later stick last page up and down together.

Fold it so it looks like some greeting or wish card.

cut out give graphic of bug and switch.

No need to cut all because we just need one piece of each.

wait for gif image to load...

as seen on image, stick conductive tape on valid given path!

only make sure to overlay tape on joints properly.

using multimeter check the connection continuity.

wait for gif image to load...

How to make paper switch? is very important part of this activity.

just follow what I did on image... that's all

finally, I glued switch on its proper place on box.

I have use photo editing to explain how component will goes because of my limited resources.

But don't worry because design and instruction are full proved and tested.

Resistor is of value 1K ohm and I used general led which required less power hence we use 1k resistor for 9v battery.

Soldering is a good idea to avoid loss connection. You can solder on copper layer without burning paper so go for it.

If you don't want to solder, you can try with different options. Like one I suggest is to use same copper tape.

once your component is paced properly you can stick firefly clipart or graphic on led. You have to cover led beneath it.

Make final sure before putting battery

precaution*

LED and all DC (direct current) source have polarity viz is positive(+) and negative(-) so check it and make sure connection is right

In case you want to change to custom components then you need to recalculate everything using given formula:

Resistor = (V_source - V_led) / I_led

Here is what the final output will look like.

Hurray!!!
