# Jay & his Arduino

Date:  Jun 12, 2016

Ever since Jay Jay is in P3, start to learn about Science, he has been very eager to learn about electricity.

Especially after building the IKEA coffee table retro game console together with me.  After seeing so much wiring, he wants to know more.

Yesterday, I also design the circuit to control the valve using program for mommy’s aquaponics farm at the balcony.

Since he is hungry for this electricity knowledge, I bought him an Arduino starter kit.

It should have all the stuff to kick start the learning.

This morning, he woke up and start learning.

And he made his first circuit.  Bravo.

And he come to explain to me why the LED has long and short legs.

HaH… Pai Seh… the Electrical Engineering graduate daddy does not even know about this. And his son, Jay explain that the PWR always connect to the Anode (+, long leg) and goes out from the Cathode (-, short leg).  What a joke, but I like it very much.

Kids at P4 age, knows how to read, and that is where they begin to learn a lot.

One complaint about the projects book is the fonts are small.  hahaha But I like it as it has all the info to teach a young kid such as Jay.

The resistor.  He knows understand that a resister will absorb some energy, and turn it to heat, and the output is “lesser energy” than 5V.

Why?  Because, you cannot give full voltage to the LED, that will make it “very bright” and then, burn the LED.

And he also learn the COLOUR CODE of resistors, and be able to find 220 ohms resistor for his project.

This is his toolbox.

And now he will be playing with bread board.

Jay demo his circuit.

More switches are placed in.

You need to press both push buttons to “complete the circuit”.

That is where he leaned also how to read the circuit diagram, and what does all those symbol means.

Nowadays, I don’t have to sent him to course.  And just buy the starter kit for him to play and he will just learn on his own.  Just like the Scratch programming too.

If you have another younger kid around, of course he wants to learn too.

Kay Kay showing is changing colour egg.

For younger kids, it is safer for them to learn on the SNAP circuits.

Jay Jay also started with this.  But it is not practical.  Because it is too safety.

Kind of make kids “not afraid of” electricity.

And after using the Arduino, Jay Jay finally understands what does all these mean.  hahaha

Of course, when the kids grow a little bit older, you can let them play and design with the Little Bits.

Is a very nice electrical kids for you to design things.  For fun of course.

Kay designed his disco light party shirt using the little Bits in class.

In summary,

1.  Actually, if you are musician, you will expose your kids to all kinds of music instruments since young.  So, I am an Electrical Engineering graduates so normally, I will expose more “engineering” stuff to my kids.  That is normal.
2. What they learn from school are important.  But what they learn from “outside” of school are equally important.  That will help the kid to shape up their knowledge banks.  I definitely want my kids to be “street smart” instead of
3. Of course, if your kid don’t like it, don’t force it!  Let the kid choose what he likes to learn.  Like Jay and Kay, both of them leans towards electrical and computer engineering.  You can influence them, by exposing more related stuff to them.  But most importantly, the kids have to like it and do not force him to learn.
4. I think our home has a lot of electric appliance so it is good for them to learn how it all works.  As it is all over the place.  Also teach them “Electricity can kill you!”

This is how I inspire them to learn.  hahaha A bunch of sensors to sense the environment at home.

And Jay working on his first Raspberry Pi Zero and try to make the RetroPie working for his Kano Screen Kit.  He also learned how to burn the image onto the SD card.  Cool!  hahaha
