Push Buttons or Switches are digital inputs and are widely used in electronic projects as most systems need to respond to user commands or sensors. Reading a switch is very useful because a switch is widely used and can also represent a wide range of digital devices in real world like limit sensors, level switches, proximity switches, keypads (a combination of switches) etc. Connecting a switch to a microcontroller is straight forward, all we need is a pull-up or pull-down resistor. In this article we are going to learn how to use MikroC Pro for PIC to read the status of a switch.
An 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. In this article we will learn how to connect and switch on and off various LEDs to a microcontroller using MikroC Pro for PIC Compiler. This is the simplest project a beginner in embedded programming can start with before attempting any complex projects as we have learned from the Introduction to MikroC Pro for PIC article.
The aim of this course is to teach you how to develop microcontroller based electronic systems using MikroC Pro for PIC Compiler. MikroC Pro for PIC is a powerful, feature rich compiler fro PIC microcontrollers from Mikroelekronika. It is easy to learn and easy to use with a highly advanced integrated development environment (IDE), ANSI compliant compiler, broad set of easy to use hardware and software libraries, comprehensive documentation and plenty of ready to run examples.
