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).

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 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.

Arduino based RGB Colour Code GeneratorRed Green and Blue (RGB) colour is the basic colour to generate various colours by mixing. The introduction of new colour is done by merging or mixing of each colour in a particular proportion. This technique is used in TV’s, Mobiles...etc., similarly on web designing using HTML or any other language requires the HEX code of a particular colour to design. Presented here the circuit to know about the concept of colour generating and the HEX code of that colour.

The circuit diagram of the RGB colour code generator is shown in figure enclosed as an attachment. It is built around popular Arduino Uno board, 16x2 LCD, RGB LED and few other components. The Arduino board is the brain of the circuit which performs the colour generation by Pulse Width Modulation (PWM).

Intel Collaborates with Honeywell and Launches Intel Connected Logistics PlatformIntel has officially announced the launch of Intel Connected Logistics Platform (Intel CLP) to give companies unprecedented levels of insight into the status of the assets during their journey through the supply chain. This would help them to make intelligent, real-time decisions that can minimize loss or spoilage of freight, maximize asset utilization and optimize end-to-end supply chain operations.
 
This announcement was made in conjunction while Honeywell unveiled its Connected Freight Solution which is based on Intel’s Connected Logistics Platform. As per researchers’ report, one of the biggest challenges faced by 89% of logistics and shipment service providers is that there is a lack for visibility into the status of their supply chain.

Making Voltage Guard using OPAM and SCR (Part 12/13)

Making Voltage Guard using OPAM and SCRIn the previous projects, a capacitor for smoothing AC to DC converted signal was used. The purpose of using the filtering capacitor was to protect the load circuit from any fluctuations and ripples in the input voltage. The fluctuations or ripples are quite common when the circuits are powered ON and switched ON or OFF suddenly.

In this project, a more robust circuit to handle input fluctuations is designed. The circuit is built using OPAM and SCR. It is used to operate a relay which controls the supply to the load. A rectified 12V supply is assumed at the input of the circuit and same voltage without ripples will be obtained at the output.

Using Inductive coupling for charging the devicesWith new era, we experience a different type of technology, almost in every sphere, which is more or less an up gradation of its following. Their only aim is to make life simpler and little advanced. But as far as charging of a device is concerned, we haven’t seen much changes in our last decade. We are still confined to traditional wire system of charging.

With this post by mepits, an attempt is taken to make a device or a system, which can charge up multiple systems and free our world with those tangled wires. This is a step ahead to become wireless power transfer using inductive coupling. The transmission of wireless power by using inductive coupling is one of the reliable methods to charge devices.

Capacitive Touch Controlled Home Automation SystemA home automation system allows controlling the home appliances from a remote control. The remote control can be a wireless remote or a mobile controlled remote system. In many home automation systems, instead of wireless control, the appliances are controlled by the remote station where keys or button directly interfaced to home automation circuit control switching of the appliances. In this project, similar control station with capacitive touch sensors is used to switch devices ON or OFF. 
 
A capacitive touch sensor feeds back user input in the form of analog voltage to a microcontroller pin. The sensor works on the principle of capacitance. It can be made by a single metal plate connecting two terminals. The finger can serve as the other plate of the capacitor and air between the finger and the metal plate serves as the dielectric.
