In this tutorial we will develop a simple but powerful Iot thermometer using 32-bit SAM MCU,some mikroElectronika clickboards and Zerynth App.


]]>Zerynth App]]> is a mobile application for Android and iOS that allows fast prototyping of graphical interfaces for your IoT projects.


With Zerynth App you can turn any mobile into the controller and display for smart objects and IoT systems! In particular, you can manage and control the connected devices programmed with Zerynth, enabling a bidirectional communication channel between them and your mobile.

Emergency System for Mine Workers

Emrgency System at MiningMine workers have a harsh job. They have to work deep down the earth. At such depths, they are almost disconnected from the everything and everyone. Even the mobile network does not work at those depths. The loss of connectivity leads to delay in any help in case of a danger or underground mishap. This project is built to detect any danger in advance and relay alert among the mine workers. Though most wireless networks don't work underground, small-distance radio communication can be used in such situation.
 
The project uses a gas sensor, temperature and humidity sensor and light sensor to detect any sign of danger. The data from the sensors is sent to a computer through radio communication for continuous monitoring.

A machine consists of many sub systems working together to perform a certain task. The information from the electronic devices are retrieved from the machine sub systems as binary code. All this information is presented in a user readable formatthrough a display device. The display technology has seen a rapid growth in the past few decades from the old CRT (Cathode Ray Tube) displays to the presently in demand LCD (Liquid Crystal Display) and LED (Light Emitting Diode) displays. The LCDs and LEDs consists of two dimensional arrays of individual display units (pixels) whose number to size of display determines the clarity of the display (resolution).

Intel Plans to Integrate Thunderbolt 3 into Future Intel CPUsWith a vision for a future where, high-performance single-cable docks, 4K video, and lifelike VR are commonly accessible, Intel has announced its plans to integrate Thunderbolt 3 into future Intel CPUs. It’s also going to release the Thunderbolt protocol specification to the industry in 2018.
 
With the integration of Thunderbolt 3, the computer makers will be able to build thinner and lighter systems carrying just Thunderbolt 3 ports. For the first time, all the ports on a computer are going to be the same. Any port can charge the system and connect to Thunderbolt devices, any display and even billions of USB devices.

Arduino Based Air Pollution Control

Arduino Based Air Pollution ControlAir pollution has become a serious issue in the present times. The CO2 level is increasing due to human activities. the effect of pollution is greater in closed spaces like living rooms, cars and offices. This project is developed to detect the level of air pollution and control the pollution level in a restricted area by activating an air purifier as the level exceeds a threshold limit.

 
The system can be installed in houses, offices or cars. The project is developed in an adaptive manner. The device first takes multiple samples of air and determines a threshold level. If the level of CO2 increases the threshold level, the air purifier is activated through a relay circuit.

Adjustable Constant Current Source (Part 13/13)

Adjustable Constant Current SourceA constant current source is used to provide a constant current regardless of the input voltage and output load. These type of circuits are also used as a current limiter. Most electronic devices have a maximum current rating and if current above that rating is drawn by it, the device may get damaged or not work properly.

Therefore a lot of times constant current power supplies are required to operate electronic devices. In this project, an adjustable constant current source which supplies 25 mA constant current at the output regardless of load resistance and input voltage is designed.

An Introduction to Analog Electronics

An Introduction to Analog ElectronicsThe world of electronics is all about electrical circuits, electronic components, and interconnected technologies. All these elements can be primarily categorized as digital, analog, or a combination of both. However, here we will be focusing on the basics of the analog category in detail. Analog electronics is a branch of electronics that deals with a continuously variable signal.
 
It’s widely used in radio and audio equipment along with other applications where signals are derived from analog sensors before being converted into digital signals for subsequent storage and processing. Although digital circuits are considered as a dominant part of today’s technological world, some of the most fundamental components in a digital system are actually analog in nature. 

Stepper Motor Driving Modes

Stepper Motor Driving ModesAny 4 phase unipolar stepper motor can be driven in 3 different modes: Single coil excitation mod, double coil excitation mode, and half step excitation mode. The given project demonstrates how to drive any unipolar stepper motor in these three different modes. It uses arduino UNO board and unipolar stepper motor library to drive the stepper motor.

It also controls speed (RPM) of the motor and displays the current speed and driving mode on LCD. So let us first see the circuit diagram followed by its description and working. Complete functionality of project is because of the program downloaded into arduino board microcontroller ATMega328. The program is the soul of the project. The program (also known as sketch) is written and compiled in arduino IDE software tool.

DIY Water Presence Sensor

Private eye pi is a Raspberry Pi projects website that deals in programming and electronics of building home security. In one of their post, they have explained the process of building a flood or water presence sensor in your house, if you experience water leak in your area on frequent basis causing expensive damages. This sensor is connected to your Private EyePi alarm system which can trigger the alarm or send email alerts.

It provides a dual opportunity where one can wire the sensor directly to the Raspberry Pi or to wireless water sensor. The sensor is designed with pleated strips of metal which change as soon as it detects the presence of liquid and consequently changes the resistance for activating the internal switch. It is mounted at some height with the attached wire along with the wireless sensor or Raspberry Pi.
