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.
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.
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.
The MPLAB® Code Configurator (MCC) is a user friendly Graphical User Interface (GUI) plug-in tool for MPLAB® X IDE which generates easy to understand C code that is inserted into an MPLAB® X project, based on the settings peripherals configurations and selections made in the Graphical User Interface (GUI). The generated code can be used in any application program. When starting out with a new project using Microchip 8-bit microcontrollers, setup of the configuration and all the peripherals can be time consuming, especially for new projects. The MPLAB® Code Configurator simplifies this down to a series of simple graphical selections from the menus within the MCC.
An automatic temperature control system has the ability to monitor and control the temperature of a specified space without human intervention. This project uses a PIC microcontroller to automatically control the temperature of an area. This area could be a small plant, a house or any place or device that require a controlled temperature like an incubator (egg) for example. The desired temperature setting is entered using a keypad. The temperature of the area is measured using an analog temperature sensor. The microcontroller reads the temperature every 10 s and compares it with the desired value. If the desired value is higher than the measured value, then the heater is turned ON, if on the other hand the measured value is higher than the desired value, then the fan is switched ON. An LCD display shows the measured temperature continuously. The project is designed using MPLAB XC8 Compiler
A memory card (also called a flash memory card) is a solid-state electronic data storage device used for storing digital information. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players and also in many applications where a large amount of data has to be stored either once or continuously like in data loggers. Memory cards are small, re-writable and are able to retain data without power. In this article we will learn how to interface an SD Card with a PIC Microcontroller with SPI bus to write and read to/from an SD card with MPLAB XC8 and MPLAB Code Configurator.
Microchip Libraries for Applications (MLA) is a collection of Microchip firmware libraries, drivers, demo projects, documentation and utilities for different type of applications including USB, Graphic displays, File I/O (Memory cards), TCP IP, Smartphone and many more. Not all firmware libraries and demo projects from Microchip are distributed in this package; rather, this package includes a few specific libraries that tend to be used together. By distributing libraries that are used often together, Microchip can provide example projects that integrate the use of multiple libraries.
A GSM modem is a wireless modem that works with a GSM wireless network. GSM stands for Global System for Mobile communications, this architecture is used for mobile communication in most of the countries in the world. A wireless modem acts basically like the traditional dial-up modem, the main difference is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves. Besides the dial-up connection, GSM modem can also be used for sending and receiving SMS which is also one of the key features of GSM modem. In this article we are going to learn how to send an SMS text Message from a PIC Microcontroller using Flowcode for PIC.
