Introduction to Programming Microcontrollers with Flowcode V6

image-1665
Flowcode is one of the World’s most advanced graphical programming languages for microcontrollers. It allows you to create complex microcontroller applications with advanced peripheral interfacing which make it easy to connect wide range of devices such as switches, LCD displays, analogue sensors, SD cards, Real time clocks, RS232/RS485, GPS, GSM, Bluetooth and so on by just dragging and dropping icons onto a flowchart. No prior knowledge of programming is required to start this course but a basic knowledge of PIC microcontrollers is necessary. In this article we are going to get a quick introduction to Flowcode v6.

Digital Thermometer using Arduino and LM35 Temperature Sensor

Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using Arduino Uno. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 to +150°C

Getting Started with Flowcode for Arduino

Arduino is the open source electronics prototyping platform. It has become popular in the world of hobbyists, students, artists, programmers and professionals. Arduino was born as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. With Flowcode for Arduino, the advantages are even greater. Flowcode is one of the World’s most advanced graphical programming languages for microcontrollers. It allows you to create complex microcontroller applications with advanced peripheral interfacing which make it easy to connect wide range of devices such as switches, LCD displays, analogue sensors, SD cards, Real time clocks, RS232/RS485, GPS, GSM, Bluetooth and so on by just dragging and dropping icons onto a flowchart.

Analog to Digital Conversion – Arduino

Analog to Digital converters allow analog continuous voltages to be converted into a discreet digital numbers inside the microcontroller as the microcontroller can only process digital numbers. This can enable the Arduino to be connected to analog sensors such as temperature sensors, pressure sensors, humidity sensors, optical sensors, and power sensors. Any sensor which can generate a voltage between 0V and a maximum 5V can be used.

Interfacing LCD Display With Arduino

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 color displays, while some others incorporate back lighting so that they can be viewed in dimly lit conditions. In this tutorial we will see how to interface a 16×2 Character LCD display with Arduino. Arduino provides built in libraries for interfacing HD44870 compatible LCDs.

Using a Push Button with Arduino

Push buttons and Switches are digital inputs and are widely used in electronic projects as most systems need to respond to user commands or sensors. Reading a push button is very useful because a push button is widely used and can also represents a wide range of digital devices in real world like switches, limit sensors, level switches, proximity switches, keypads (a combination of switches) etc. In this case, we’re going to use the simplest form of sensor: a push button switch. In this tutorial we are going to learn Arduino functions to read a switch connected to Digital Inputs pins.

Blinking an LED with Arduino

A Light Emitting Diode (LED) is a semiconductor light source, when forward biased, it emits light. LEDs are used mainly to indicate the status of electronic circuits, for example to indicate that power is on or off but nowadays they are used in many applications including lighting and beam detection. All of us start learn a new programming from Hello World. In microcontroller fields the Hello World example is usually blinking an led, in this article we will learn how to Blink an LED with Arduino.

Arduino is the open source electronics prototyping platform. It has become popular in the world of hobbyists, students, artists, programmers and professionals. Arduino was born as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.
