ProCodeCG Kids Regular Coding Class – 24 Feb 2018

Standard

It was a wet and cloudy morning but kids kept coming to the class, thanks! 🙂

We had a visitor today: Ibu Inge Halim – General Manager, Banking and Financial Markets, IBM Indonesia 🙂 (on the left, in khaki blazer)

IMG_9694

Capt. BR brought her to see how kids learn and do coding 🙂

She was amazed to see the demo of Koosha’s elevator simulation 🙂

Bu Inge took a look on what each kid was doing in the class, including Cinta’s 🙂

So here’s the detail of what the kids were working on today 🙂

Ozan was going to control LED brightness via cloud

IMG_9658

First he had to try to control the brightness of the LED using potentiometer

IMG_9663

IMG_9664

IMG_9689

But there was some problems because the potentiometer didn’t seem to work to adjust the LED brightness

IMG_9670

We had replaced the potentiometer and it still didn’t work. Will sort this out next week and as the problem is solved we’re going to control it via MQTT Dash app from Ozan’s android phone 🙂

IMG_9678

Our newcomer: Fathan 🙂 *he was waiting for internet connection before he can start the lesson 😀

IMG_9659

Fathan finished learning Python with CodeCombat today

IMG_9661

And then Capt. Azriel helped him getting started with GameMaker

 

IMG_9705

Yeeay Fathan’s first game 🙂

IMG_9686

Very well done, Fathan 🙂 Thanks to Capt. Azriel for the assistance 🙂

IMG_9698

IMG_9702

Nafis (in the corner) checked his MQTT Dash App to be tested today. He forgot to bring his laptop charger so we have to use another laptop to test it 🙂

IMG_9660

Nafis task was to turn on/off a LED via cloud using his android phone

IMG_9690

and after several attempts, it worked 🙂 With the help of Ka Ozan *because he had gone through the same thing a couple weeks ago 🙂 Thanks Ka Ozan 🙂

IMG_9706

Nafis satisfied look and his sister cute making faces LOL

IMG_9709

Cinta was making her idea into reality: creating a random topic generator 🙂 She is going to create it in Python and then with Thunkable

IMG_9662

We also had students from Telkom University School of Economy and Business, interviewing the whole class about ProCodeCG 🙂

IMG_9667

And Cinta showed them some of her most awesome works 😉

IMG_9673

Capt. Syahna arrived and Cinta happily discuss her ideas to her because it was their ideas together to create this random topic generator 🙂

IMG_9710

Capt. Faris, like usual, working on the research: data crawling and tensorflow 🙂

IMG_9665

He said we need to improve the learning process because the result for certain images is like this

IMG_9696

The trend of the image recognition

IMG_9697

Vian and Ain (Ain sit on Vian’s right and we missed taking his pic today :(( ) were still doing their Minecraft Skin project together 🙂

IMG_9666

Koosha worked on loads of thing 😀

IMG_9668

He determined to make his elevator simulator works 🙂

IMG_9672

IMG_9676

Koosha rewrote the code

IMG_9713

IMG_9677

IMG_9680

and checked again the circuits

IMG_9681

IMG_9682

And it worked 🙂 Yaaay well done!

IMG_9684 2

IMG_9692

Then we added LCD to display the info about the elevator

IMG_9712

There were still some glitches but we will work on it next week 😉 So far it’s been a huge progress today 😉

IMG_9714

Azriel was given a new challenge: to create a running text in Minecraft

IMG_9674

but it was too hard so we changed it to creating elevator 🙂

IMG_9675

like always, Azriel found each and every way to do it 🙂

IMG_9687

The elevator

IMG_9688

that goes up 🙂 We’re going to find out how to make it move in both directions 😉

IMG_9691

That’s it for today! Will be reporting again next week! 🙂

ProCodeCG Kids Regular Coding Class – 27 Jan 2018

Standard

Hello from our kids regular coding class 🙂

Earlier, only a few kids

Untitled

Untitled

later…

Untitled

Today we’re thinking about designing an automatic folding table 🙂 We sketched some designs 😉

Untitled

Capt. Awa was assigned to create a prototype 😀

Untitled

But Awa wanted to do his trashbin project 🙂

Untitled

He wanted the LED to be activated each time the ultrasonic sensor detect something

Untitled

 

Untitled

Yep it worked 🙂

Untitled

Awa was also exploring the buzzer to do some morse 🙂

Untitled

And after a while discussing about the folding table prototype, Awa chose to collaborate with Ain, doing the prototyping in Minecraft 😀 😀 😀

Untitled

Untitled

Ain was given several challenges to create in Minecraft. He was paired with Awa to connect Minecraft to the outside world 🙂

Untitled

Ozan started to install MQTT Dash on Android and MQTT.fx on Mac because he’s going to learn some IoT implementation 🙂

Untitled

We got Sulaiman exploring his Minecraft Modding skills

Untitled

 

Untitled

Untitled

Sulaiman is very generous and kind kid 🙂 He voluntarily helped others (Kinan on the left, Silmi on the right)

Untitled

Sulaiman is going to be a good Captain one day 🙂

Untitled

Untitled

Capt. Azriel (left) helped too

Untitled

Today we got two newcomers: Silmi

Untitled

and Kinan

Untitled

They both went through intro to programming

Untitled

Untitled

And after they finished the first part

Untitled

Untitled

they started the next

Untitled

Untitled

Vian still so into Minecraft command block, he created lots of stuff in there

Untitled

Untitled

Untitled

Untitled

Untitled

Untitled

Untitled

Nanin continued to learn how to make a website 🙂

Untitled

under Capt. Azriel supervision

Untitled

Untitled

Untitled

the temporary result 😉

Untitled

Nanin also designed some header for the website by herself 😉 Very nice 🙂

Untitled

Capt. Faris was very busy with his project

Untitled

Untitled

Untitled

Using OpenCV to recognize objects in video

Untitled

Last week we had already successfully recognize objects on images, along with the numbers of the objects. Today we use videos instead of images

Untitled

Untitled

the processing using matrices

Untitled

The first video (recognized the object as bear: 94%

Untitled

Untitled

person:59%

Untitled

the second video (we’d like to know if the system could recognize a human being upside down :D)

 

Untitled

Untitled

Yes it recognized this one as a person 😀

Untitled

Will do more experiments on this one next week 🙂

 

 

 

 

 

 

ProCodeCG – BDV – codeMeetUp() #116 IoT Series Day #4 – 20 Nov 2017

Standard

The last day of ProCodeCG – BDV – codeMeetUp() #116 IoT Series 🙂

ProCodeCG - codeMeetUp() #116- IoT Weather Programming Series 4:4 - small

Today we made sure everybody could follow what have been learnt in the previous class

IMG_2541

IMG_2542 IMG_2543

IMG_2544 IMG_2545

IMG_2546

After we’re sure that everybody can gather data from temperature and humidity sensor, we moved on to connecting it to the cloud

IMG_2547

IMG_2548 IMG_2549

Then we learned IoT & MQTT

IMG_2550

And experimenting with publishing and subscribing to MQTT 🙂

IMG_2551

We can do it from mobile apps too 🙂

IMG_2552

We can control (and being controlled LED) of any ESPectro subscribing to “led1” topic and can send and receive text to anyone subscribing and publishing to “pesan” topic

IMG_2553

IMG_2554

At the end we learned to continuously publish data to MQTT, and the next step is to send temperature and humidity data

IMG_2555

This us 😉

IMG_2556

Thanks so much all, thanks so much BDV, see you again soon with different topics 🙂

ProCodeCG Kids Coding Camp – IoT Programming – Day #3 – 24 June 2017

Standard

IoT Programming Coding Camp Day #3 🙂

Today we connect to a MQTT server to be able to publish and subscribe to a topic so we can control our ESPectro remotely via cloud 🙂

We connected to a MQTT server running on one of the computer of the class and also connected to an online MQTT server 😉

IMG_2259 IMG_2260

IMG_2261 IMG_2263

IMG_2265 IMG_2266

IMG_2267 IMG_2268

IMG_2269

We can control the ESPectro via mobile too 🙂

IMG_2273

IMG_2274

The lessons today required hard work and patience 🙂

IMG_2278

IMG_2279 IMG_2281

IMG_2282 IMG_2283

We code till we drop LOL

We’ve learned so much today, we deserve certificates 🙂 Yaaay 🙂

IMG_2285

Picking up after ourselves 😉

Can’t believe coding camp is over 🙂 See you again soon and happy holiday 🙂
