The world around us is changing at a much faster pace than any one can anticipate. The world of “computing” has already seen great shifts from Desktops to Notebooks to Smartphones and Tablets. The coming decade will be more focused on mobile computing and cloud computing. Here in this article, I am listing some of the best and really useful applications released in Android market (aka Google Play), that comes handy for any one who is working in Electrical and Electronics industries/professions.
ElectroDroid – is the most popular and useful application in Android market for an electronics engineer. This app is a collection of many simple and useful tools like Resistor color code calculator, Filter value calculator, Inductor color code calculator, SMD resistor code calculator, LED resistor calculator etc. The App also has a great collection of pin out diagrams of USB port, Parallel port, Ethernet port, VGA connector, Firewire connector etc and other resources and references which lists PIC micro controller database, ISP specs of AVR and PIC, Circuit schematic symbol reference, ASCII table references, Battery references etc. This application has been downloaded by more than 10,000,00 smart phone devices and has been rated by more than 30,000 users. If you are looking for a much better version of the app without ads, you can buy it from the Google Play store (Electrodroid Pro) for less than 3 USD.
EveryCircuit - is a simple and beautiful application for android which helps you to build and simulate circuit ideas. It has a really good & simple user interface which begins with a workspace where you can start building your circuits. You can add your components like resistors, capacitors, inductors, power sources, signal sources etc and wire them together to complete the circuit. You can alter the values of each and every component and then finally Run/Simulate them. You will see the current flow, input and output waveforms graphically represented etc when you run the circuit you have built. You can alter the component values in real time and see the changes in output instantly. Additionally the app developers have provided a set of built in circuit applications like inverting amplifier, rectifier circuits, voltage regulator etc which the user can simulate instantly to learn the working of these circuits. The attractive feature is the graphical representation (animation) of the electron flow, input and output signals which helps the user to understand the circuit functioning within no time. Their free version doesn’t have a large work space area, which limits the number of components you can play with. They also have limited their component library in their free application. I think they have deliberately done this to promote their paid application – EveryCircuit Premium – which they sell for around 10 USD. They have sold more than 10,000 apps in Play store, which shows people are quiet interested in their app. I suggest you try their Free app first and if you like it, go ahead and buy the premium version.
PIC Microdatabase - another free app from IERO, which integrates well with ElectroDroid app. This app is nothing more than a database of PIC micro controllers manufactured by Microchip. This app lists all PIC and dsPIC family of controllers in an easy to use user interface. Features and specifications of all controllers along with pinout diagrams of select ones are available. The most attractive feature is a search functionality in which you can search for a controller with particular features you would like to have.As an example you can search for controller from PIC that belongs to a particular PIC family like PIC 10, with specific EPROM values, specific RAM, USB 2.0 or higher, specific internal oscillator values etc. The app will output all PIC controllers that matches your search criterias. So far more than 10,0000 users have downloaded this application.
