Programming with Arduino

Presently, in Singapore and most of the countries, many students have avoided doing STEM courses because it is difficult and it does not pay them well after graduation. The country is experiencing lack of good engineers, technologists and scientists [1], [2]. An initiative has been started to introduce STEM to students at young age in a fun and yet effective learning way. Team TBSS designed and developed a 6-hour STEM targeting pupils between 10 and 12 years old who are reading primary 4 and primary 6 in school. The program has been conducted several times with Henry Park Primary School. The process, findings and experiences will be shared in this paper.

In Singapore, majority of the parents want their children to pursue a medical, legal or accounting career, and students prefer business, finance or management courses.  The main reason being engineering is one of the most difficult courses and engineering career does not fetch as good remuneration as the other professional careers.  The nation is experiencing lack of engineering, technologists and scientists.  The “Inspire Me, Start Early” initiative attempts to introduce STEM to students at young age, in a fun and yet effective learning way.  Team TBSS had designed and developed a 6-hour STEM targeting pupils between 10 and 12 years old who are reading primary 4 and primary 6 education.  The program was conducted twice with a primary school school.  The process, findings and experiences will be shared in this presentation.

Coal mine is a hazardous place in which numerous lethal variables are risky for human life, particularly when impacts happen. Rescue team typically doesn't have a clue about the real circumstance of the mine passage. Accordingly, it might be exceptionally risky for rescuers to go into mine passages to inquiry survivors without distinguishing ecological data previously. To tackle this issue, robot is created for helping individuals to do the rescue work. The robot is used for detecting the explosion environment of coal mine. We developed a prototype of a fully autonomous robot which can be used to indicate presence of harmful gases inside a mine for mine rescue operations in case of emergencies caused by natural calamities such as explosion. Coal mine rescue robot is a sort of portable robot. It can go into blast environment and discover gas content.

Enthusiasts in transforming the educational scene are currently glimpse the possibility of "Maker Education" enabling experiences and apprenticeship of student's interest favoring protagonism. Learning by making have always been present in education, however understanding how Maker Education configures and how this relation between the Maker Movement and education in a modern digital context is essential in the induction of a Maker Education that does not involve building things with your own hand using material such as paper and glue, but made of people and their attitudes, their social and contextual experiences in communities.

Semikonduktor adalah sebuah bahan dengan konduktivitas listrik yang berada di antara insulator dan konduktor. Semikonduktor disebut juga sebagai bahan setengah penghantar listrik. Sebuah semikonduktor bersifat sebagai insulator pada temperatur yang sangat rendah, namun pada temperatur ruangan besifat sebagai konduktor. Bahan semikonduksi yang sering digunakan adalah silikon, germanium, dan gallium arsenide. Semikonduktor sangat berguna dalam bidang elektronik, karena konduktansinya yang dapat diubah-ubah dengan menyuntikkan materi lain (biasa disebut pendonor elektron). Salah satu alasan utama kegunaan semikonduktor dalam elektronik adalah sifat elektroniknya dapat diubah banyak dalam sebuah cara terkontrol dengan menambah sejumlah kecil ketidakmurnian. Ketidakmurnian ini disebut dopan.[1] Semikonduktor adalah bahan dengan konduktivitas listrik yang berada di antara insulator dan konduktor.

The aim of this idea is to show an early stage draft for measuring the electrical resistance in a designed/elaborated textile printed sensor with a mobile Arduino microcontroller. The textile sensor was developed by the screen printing technique based on a water dispersion of carbon nanotubes printing composition. By stretching and squeezing the T-shirt during breathing, we change the electrical resistances of the printed sensor. The measured resistance corresponds to the number of breaths of a person wearing it. The microcontroller can calculate the number of breaths as a number of electrical resistance peaks which can lead to monitoring human live parameters.

In this paper, an overview of the potentiality of Arduino boards will be presented, together with the description of the Arduino interfacing with light multi-sensors. These sensors can be arranged in linear arrays or in a matrix configuration (CCD or CMOS type cameras), and are equipped with tens, hundreds or even thousands of elements whose size ranges from a few microns to tens of microns. The use of these sensors requires electronics that have high time accuracy, since they work due to regular pulses sent by an external source, and, furthermore, the ability to digitize and store voltage signals precisely and quickly. We will show that, with the appropriate settings, a simple Arduino board can handle both 1-D and 2-D optical sensors. Finally, we will describe a solar compass, capable to provide the North direction with a very high degree of accuracy, made with such a board coupled to one of the tested optical array sensors.

Hyperbilirubinemia, an excessive amount of bilirubin in the blood, is a common condition in
premature infants. The excess amount leads to a deadly disease called jaundice. Optical devices
called bilibunometers are used to measure the concentration of bilirubin in a non-invasive way.
These devices use a single wavelength light source in the range of bilirubin absorption spectrum.
These leads to inaccurate results due to the presence of other substances in the blood like
melanin and hemoglobin. Therefore, in this project, three light sources with the maximum
absorption range of bilirubin, melanin, and hemoglobin is considered. Using Beer Lambert law
the total absorbance, due to the three pigments, at red, green and blue wavelength is calculated
and displayed on LCD. Then independent component analysis is performed to separate and
minimize melanin and hemoglobin interference from the total absorbance of the three pigments.
As a result, independent concentration of bilirubin, melanin and hemoglobin was found. Each
concentration is displayed on MATLAB.

Control higher power devices like lights is difficult and possibly dangerous when power line voltages are being controlled. There are significant differences in controlling AC power compared to DC. The purpose of this paper is to control alternative current through inexpensive wireless technologies sensors with Arduino. The Infrared signals range is short and limited therefore we can control in limited range. The Radio Frequency signals range is wide and strength is very high. Therefore, we can control in wide range with better signal strength.

Neste artigo apresentamos resultados parciais de uma pesquisa que tem como questão central analisar o modo como alunos do Ensino Médio de uma escola pública desenvolvem pequenos projetos de Robótica. O objetivo é construir uma proposta metodológica a fim de inseri-la no contexto didático do Ensino Médio, norteado pelo construcionismo e preconizando Cenários Investigativos, visando o “aprender a aprender”, em um ambiente menos assimétrico e de parceria entre professor e alunos. A investigação, de cunho qualitativo, através da observação participante, apontou seu olhar para uma dupla de estudantes que, colaborativamente, optou pela construção de um detector de fumaça microcontrolado por uma placa programável Arduino. Nossos resultados apontam positivamente para um aprendizado ativo e potencialmente interdisciplinar, mais autônomo, em que as habilidades desenvolvidas vão além dos conhecimentos específicos da Robótica, visto que os alunos se ocupavam em planejar, avaliar e tomar decisõe...

   – he very rapid development of Information and Communication Technology (ICT) has an impact on all human activities today. The number of assistive media created by technology in agriculture has begun to emerge, apart from facilitating human work, the creation of these tools is considered to be able to shorten time and make harvests easier and faster. Many problems arise from farmers, especially in the problem of managing the waters for rice fields, one of which is when water does not flow from the springs, causing the rice fields to dry up and make rice and other plants die. The need for a technological innovation that functions as a water flow control system in rice field using a water level sensor that is applied with electronic programs and components, namely Arduino, is considered to be more effective, so that the irrigation system in paddy fields can be controlled and help solve the difficulties that occur.Keywords  : water Level Sensor, ArduinoAbstrak- Perkembangan Teknolog...

ABSTRAKSI: Saat ini futsal telah mendunia dan sudah menjadi konsumsi berbagai usia dan kalangan karena futsal tidak memandang tua muda ataupun kaya miskin semua melebur menjadi satu disini. Futsal dapat dimainkan pada siang ataupun malam. Namun untuk mengadakan pertandingan di malam hari, kita memerlukan sistem instalasi penerangan yang baik. Saat ini untuk dapat menyalakan sistem penerangan yang ada, masih menggunakan saklar. Dalam hal ini, sistem lampu penerangan konvensional pada kebanyakan lapangan futsal ketika diadakan pertandingan malam biasanya setelah selesai pertandingan, lampu lapangannya dibiarkan tetap menyala. Hal ini membuat pemakaian listrik untuk penerangan lapangan futsal sangat boros dan tidak efisien dikarenakan memakai daya yang tidak sedikit untuk dapat menerangi setiap sudut lapangan.Dalam proyek akhir ini telah direalisasikan suatu sistem otomatisasi yang terintegrasi dengan sistem pencahayaan lapangan futsal yang ada, yaitu dengan teknologi. Pada pintu lapan...
