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

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

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_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 🙂
