16x2 Character LCD

Interfacing LCD with 8051 using Keil C – AT89C51

Liquid Crystal Display (LCD) is very commonly used electronic display module and having a wide range of applications such as calculators, laptops, mobile phones etc. 16x2 character lcd display is very basic module which is commonly used in electronics devices and projects. It can display 2 lines of 16 characters. Each character is displayed using 5x7 or 5x10 pixel matrix. 16x2 Character LCD Interfacing 16x2 LCD with 8051 using Keil C is bit complex because there is no powerful libraries in Keil...

Blinking LED using Atmega32 Microcontroller and Atmel Studio

Similar to printing 'Hello World' in C or C++, the very first step towards programming a microcontroller is Blinking a LED with a delay. Atmega32 is a very popular high performance 8 bit AVR Microcontroller. For this example project we need to use two registers DDR and PORT. DDR stands for Data Direction Register, it determines the direction (Input/Output) of each pins on the microcontroller. HIGH at DDR register makes corresponding pin Output while LOW at DDR register makes corresponding...

PCB Designing using OrCad Layout 10.5

OrCad is a highly developed and complex software that provides affordable and high performance PCB designing tools for small and industrial PCB designers. But for an electronic hobbyist, OrCad may seems to be highly complicated and time consuming when compared to other PCB designing tools. OrCad 9.2 is the commonly used version but it is not compatible with 64 bit and the next best choice is OrCad 10.5 as higher versions of OrCad are highly complicated. Thus in this tutorial, we will show...

GLCD

Interfacing GLCD with PIC Microcontroller

I have already posted about Interfacing character LCD with PIC Microcontrollers. By using GLCD (Graphical LCD) we can present information in a better and user friendly way by using any patterns or shapes. Graphical LCDs are preferred where both character and graphical representation are required. Compared to Character LCD, GLCD is a bit complex and we need a powerful graphic library. MikroC PRO for PIC Microcontrollers provides powerful built in libraries for that. GLCD  MikroC Pro - Graphic LCD Library MikroC Pro for PIC Microcontrollers...

Ultrasonic Distance Sensor

Interfacing Ultrasonic Distance Sensor : ASCII Output with PIC Microcontroller

In some of our projects, we may want to measure the distance of an object from a point. Ultrasonic Distance Sensors are the best sensor which provides stable, accurate, precise, non-contact distance measurements from 2cm to 4m. Ultrasonic Sensors can be used to measure distance between moving or stationary objects. Being very accurate and stable, these devices find large number of applications in robotics fields. For example it can be used as an excellent replacement for IR sensors in  a Micromouse. In...

relay

Interfacing Relay with PIC Microcontroller

A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relay isolates low power circuits from high power circuits. It is activated by energizing a coil wounded on a soft iron core. For detailed working of relay please visit this page. A relay should not be directly connected to a microcontroller, it needs a driving circuit. A relay should not be connected directly to a microcontroller due to following reasons.. A microcontroller is not able...
