Interfacing a Relay with PIC Microcontroller – MikroC

image-321
A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relays isolate as well low power circuits from high power circuits, this is a good feature especially for safety reasons a section of the circuit with high dangerous voltage/current could be isolated from the user. When a low voltage is applied to the relay (coil wounded on a soft iron core), this coil becomes a magnet which in turns energizes the soft iron core which closes or open the high voltage/current contacts of the relay. A relay can be used to switch higher power devices such as motors, light bulbs solenoids etc. In this article we are going to learn how to interface a relay to a PIC Microcontroller, we will learn as well how to control devices connected to the relay using MikroC compiler.

Getting Started with ENC28J60 Ethernet Controller with Microcontrollers

image-2104
Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to one another. With just a network switch, many different devices can easily communicate with one another with Ethernet, allowing different devices and equipment to be accessed remotely and this also provides a cost-effective and reliable means of remote control and monitoring, home automation, Internet of Things applications and many more. If you are using a microcontroller which does not have an integrated Ethernet peripheral, Microchip offers a serial Ethernet chip that can easily be used by any microcontroller with an SPI interface to provide Ethernet capability to the application. many compilers offer peripheral libraries to get you started in minutes.

For microcontrollers which don't have an integrated Ethernet peripheral, Microchip offers a serial Ethernet chip that can easily be used by any microcontroller with an SPI interface to provide Ethernet capability to the application. The ENC28J60 is a popular 28-pin serial Ethernet chip, 10BASE-T stand alone Ethernet Controller with SPI interface, on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface. In this article we will learn how to use the ENC28J60 Ethernet controller with MikroC Pro for PIC SPI Ethernet ENC28J60 Library.

Web-Based Control and Monitoring with PIC Microcontroller – MikroC

Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to one another. In this project we are going to learn how to control any device like an LED, a relay, a light bulb, a motor and so on connected to a PIC Microcontroller from a remote location using just a web browser. An operator can use a computer, tablet or even a cellphone to control a device at a remote location. With the help of a router connected to the internet, this device can be controlled anywhere from the world in real time. Connecting to a Microcontroller using a web browser is the easiest and reliable method of establishing connectivity and above all there is no need to develop a special Graphical User Interface software on the PC or cellphone for that matter as all PCs' operating systems already have a built-in web browser or one can download one of the free other web browsers like Google chrome or Mozilla firefox for example.

Getting Started 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.

Getting Started with Raspberry Pi

Raspberry Pi is a small credit card sized computer, It is very cheap compared to the traditional computers, the Raspberry Pi Foundation has arrangements with a few manufacturers from whom you can buy a Pi directly at $25 - $35. The Raspberry Pi unlike the traditional computer, it has the ability to integrate with electronics projects. Raspberry Pi to control devices that a microcontroller can control like LEDs, relays, LCDs etc. A Raspberry Pi is better used where more processing power and connectivity is needed like for exemple when you want to remotely access a temperature sensor via the web to change its settings and download temperature log files and more in general Internet of Things (IoT) and Home Automation applications you should consider using the Raspberry Pi.
