In simple terms, a variable is a location in memory where we can store information. The type of variable created must match the correct type of information that has to be stored in, if we want to store a number, we cannot store it in a location destined to store strings (characters). In this article we introduce the different types of Flowcode variables.
Decisions are vital in any programming languages, in most of the cases, we need to know IF a certain CONDITION has been met so that we can do certain things or select an option (CASE OPTION) from a number of options. In this article we introduce the different types of Flowcode decision statements, we will learn how an IF statement can be created using Flowcode to select a specific condition among other choices
Switches are digital inputs and are widely used in electronic projects as most systems need to respond to user commands or sensors. Connecting a switch is very useful because a switch can represent a wide range of digital devices in real world like limit sensors, level switches, proximity switches, keypads (a combination of switches) etc. With flowcode it is very easy to connect a switch to any PORT of microcontroller all you need to do is to click on a switch component and then drag and drop an Input Icon on the flowchart.
LCDs are alphanumeric (or graphical) displays, which are frequently used in microcontroller based applications which require some information to be displayed to the user. There are many devices in the market which come in different shapes and sizes. Some LCDs have 40 or more character lengths with the capability to display several lines. Some other LCD displays can be programmed to display graphic images. Some modules offer colour displays, while some others incorporate back lighting so that they can be viewed in dimly lit conditions. For most PIC programming languages, the LCD is often one of the last things you learn as it is quite complicated to get working. However, in Flowcode you don't need to know what is going on inside, all you have to do is drag and drop some few icons on the flowchart and flowcode will sort out the rest for you.
The 7-segment display is the earliest type of an electronic display that uses 7 LEDs bars arranged in a way that can be used show the numbers 0 - 9. (actually 8 segments if you count the decimal point, but the generic name adopted is 7-segment display.) These devices are commonly used in digital clocks, electronic meters, counters, signalling, and other equipment for displaying numeric only data. Flowcode has components for both a quad 7-segment display which can display 4 digits and for a single 7-segment display.
Analog to Digital converters allow analog continuous voltages to be converted into a discreet digital numbers inside the PIC as the PIC can only process digital numbers. This can enable a PIC to be connected to analog sensors such as temperature sensors, pressure sensors, humidity sensors, optical sensors, and power sensors. This is a nice feature to use as most of PIC microcontrollers today have built-in analog to digital converters (ADC) with the number of channels depending on the number of pins a particular microcontroller have. Flowcode has an ADC component that samples analogue voltage input levels in relation to the reference voltage. the resulting value is then stored in memory ready to be retrieved as needed.
How do we achieve our goals in life? How do we stay focus to our goals? You might be twenty or twenty five still young ambitious with a set of goals to achieve in your life but before YOU CAN EVEN NOTICE IT, you are now forty or fifty your dreams start fading away, you haven't achieved any thing.... How can you AVOID THIS FROM HAPPENING? People who are clueless about how the world works, people who spend their whole lives on the outside looking in, use myth as a comforting excuse for their own lack of goal attainment. Some will go even far to blame the position of stars and planets for their failures. Once you spend even a little time with successful people, you'll notice something startling: they all have well defined goals which they focus on. They go after the things they want and nail them like a wild dog chasing a rabbit.
Your CV will be the first impression a recruiter or employer has of you. In a competitive job market, you need a very good CV to succeed in securing your interview. It describes what sets you aside from other applicants and what makes your application special and relevant to that specific job vacancy. This is the first step to secure your job so spend some good time getting it right, remember your potential new employer spends considerable amount of time and resources in the recruitment process and hiring and orientation of new employees is expensive and time consuming. If you put an effort to write a great CV, there is a strong chance that the reader will notice you and invite you for an interview. In this article we take you step by step on how to write a professional CV for your dream job.
After reading How to write a CV article, you should get a good idea of the importance of writing a great CV. Without a well laid out CV you are really wasting your time applying for jobs. In this section, there are a few downloadable CV templates in Microsoft word for you to customize for your need. Here you will find template CVs for Matric school leavers, recent graduates, junior positions, somebody looking for internship, P1 or P2, skilled technician, junior and skilled engineer, junior medical doctor etc.
