Today we learn Node-RED with Arduino for IoT 🙂
starting with installations
and then creating nodes
and make dashboard 🙂
then we start to wire Arduino and sensors
and control the circuit via Node-RED 😉
and then connect more complex nodes
and then show the sensor readings to dashboard 😉
we covered all the tasks should be done today, there are some intermittent bugs related to OS, software configurations etc., but in general the training went very well 🙂
Thanks for having ProCodeCG 🙂
Day #2 of Data Science Training at School of Computing – Telkom University 🙂
Today we learn how to crawl data from Instagram, processing it, make analysis and visualisation
The data
The results
this is the result of very latest topics 😉
Thank you very much to School of Computing – Telkom University giving ProCodeCG an honour to share a bit what we know about Data Science 🙂
Today is the first day of Data Science Training at School of Computing – Telkom University 🙂
The training room
What we learned today is how to use Python for Data Science 🙂
we learned to process different kinds of data, from txt, csv, json to xml. Tomorrow we will learn how to process data in graphql format 😉
The codes
The data
Some of the results 
The class
Tomorrow will do data crawling, parsing, analysing and visualising 😉
Day #2. We start to think about what games to make 😉
This is how we do brainstorming and designing the game 🙂
We have LOTS of ideas but we will choose one to create today: Matching Game. The game will be about matching pictures or cards. The codes:
The prototype of the game 🙂 We took a lot of time to figure out how to identify same objects without too many complicated stuff 🙂
Great, at least it works now. The main logics have been coded, the hard work is now on creating assets 😀
Creating games, even the simplest ones need hard work, persistency and experience.
There’s no such things as shortcut 🙂 We have to spend time and work 🙂
*Photos and videos are also available here
Day #1 of Creating Games Private Class 🙂 The target for 3 days is to be able to make a game that is eligible to be uploaded to PlayStore 😉
Before start to create a game, one should learn basic principals of programming. Today Fariq has to go through some tasks to learn the logics and basic skills to create a game
Doing these kind of challenges and solving problems can help us to be more creative and flexible
On the left side is a tool to create games: GameMaker
Even though this tools is simple, it is powerful enough to create awesome games
and also to learn programming
An example of a simple game created with Game Maker 🙂 The first game of Fariq 🙂
*Photos are also available here
It is a great honor today for ProCodeCG to be invited to give a workshop about IoT to one of the most prominent training center in Indonesia: INIXINDO 🙂
Preparation before the class
The stuff
The presentation
The class
Some screenshots of what we learned today
A great day with great persons! 🙂
Wishing to be able to collaborate with INIXINDO again very soon 🙂 Thanks so much for having us 😉
Today we trained lecturers for Politeknik Negeri Pontianak on how to do data acquisition from current sensors 🙂
Class preparation
We split the team into two: hardware and software. The hardware team started to assemble the components
while the software team installing the application and libraries
ESPectro basic testing: blink
and neopixel animation
Then we’re ready to connect ESPectro to the circuit and sensor
We compared the circuit with the one that has been tested and verified
Still didn’t work
It took lots of retrying, switching components and we tried every solution possible and think of every source of errors
still didn’t work
We just kept trying
and after we changed the resistors with metal film ones, it worked! 😀
Current reading when the switch is on
when off
when on and off again
The effort was worth it 🙂 We finally finished the training and ready to collect data for further research and analysis 🙂
Today we had a training on gathering data from sensors using DHT11 and MLX90614 using ESPectro development board 🙂
Setting up before the class started
We used two different computers to make sure we can do lots of things simultaneously 🙂
we also have to make sure we have reliable internet connection and a toolbox full of anything we might need 😉
we tested MLX90614 with Arduino
and it worked. Next we will use ESPectro to be able to send the data via cloud 🙂
We’re going to use the sensors to measure battery temperature
We’re going to use multiple sensors to measure multiple batteries, so we’ve got lots of things to do, and will continue the training on Wednesday 🙂
Today we started the first day of Family Coding Crash Course on Arduino 🙂 These are Sadid and Razin, they are brothers and they are so interested in coding 🙂
On the left, Pak Bullit Sesariza (the uncle, who are an expert in programming) and on the right is Pak Budi Rahardjo, one of the mentor of today 🙂
The course will be from Mon – Fri. We only had these two for Monday and Tuesday but their mom and aunt will join us on Wednesday and Thursday.
The first thing to do was to download and install the latest version of Arduino Software 🙂
Then we do the Blink test to on board Arduino LED.
We learned about breadboard, resistor (and how to calculate the value) and LED, and then we connected Arduino to a breadboard with LED an resistor and made it blink 🙂
Then we add more LEDs and resistors 🙂
It was supposed to be 8 LED but the breadboard was too small, only 4 LEDs fit 🙂
After Sadid and Razin got the LEDs blinking (in one way and many ways), we use a LED module
ProCodeCG LED, which is a hassle-free way to play with LED (without having to deal with those jumpers and resistors LOL)
The previous code uploaded to Arduino worked right away (notice that only 4 LEDs activated :))
We had a great time
3 hours flew very fast 😀 It wasn’t enough 🙂
We will learn how to use button and RGB LED tomorrow 🙂
Today we, DyCode and ProCodeCG collaborate to give a training on iOS App Development with Swift at Bandung Digital Valley (BDV)!
This is the participants and the trainers before the training started 🙂 Happy and fresh, glowing and shining 😀
This is Andri Yadi, the CEO of DyCode, a leading company of training and apps development. He is also President of ID-Objective-C, the one and only in Indonesia.
This is Bayu Wicaksono, Mobile Apps Team Lead of DyCode. A very hardcore and qualified programmer.
This is us after lunch break. A bit burnt out after a hard Swift coding session 😀
We also got a guest from IBM, this is Rudi Suryadi – System Architect, explaining about Development War Day. Register before 18 April 2015, there are merchandises for those who sign up! 🙂
And DyCode surprised us with a bonus topic: INTRO TO WATCHKIT! WOW 🙂
Ok. Everybody wants to lead on technology and programming, should learn from a leading trainer. DyCode offers several trainings on apps development. Visit http://edu.dycode.co.id/ for more info.
We also gave merchandises away including this very cool Swift T-Shirt! It is given to The Most Awesome Participant, which was Seterhen Akbar (Saska) from Labtek INDIE!
And to make it even, as DyCode had twisted our brains to keep up with all the coding stuff, ProCodeCG’s Mentor, Budi Rahardjo gave DyCode’s CEO a book about Elliptic Curve Cryptography (written by Pak Budi Rahardjo and also ProCodeCG’s Founder Marisa Paryasto). So that DyCode will experience more or less the same headache LOL
Another gift, a USB from Microsoft Azure was given to the youngest participant: Rio Rizki Wijaya.
All of the participants today, along with DyCode trainers and ProCodeCG personnels will get together again on ProCodeCG codeMeetUp next week, Monday 13 April 2015!
End of the report today 🙂
Code - and rule the world
