Push Button Switch

Using Push Button Switch with 8051 and Keil C – AT89C51

This tutorial is for beginners in the field of microcontroller. In this case the microcontroller is AT89C51, a reprogrammable derivative of 8051. This purpose of this tutorial is to familiarize with the use of push button switch with the microcontroller. It will be useful whenever a decision is to be made according to the press of a switch. If you are not yet started with 8051 with Keil C please refer this tutorial Blinking Led using 8051 and Keil C. Circuit Diagram LED and Switch Interfacing with AT89C51...

AT89C51

LED Blinking using 8051 Microcontroller and Keil C – AT89C51

8051 Microcontroller is a programmable device which is used for controlling purpose. Basically 8051 controller is Mask programmable means it will programmed at the time of manufacturing and will not programmed again, there is a derivative of 8051 microcontroller, 89c51 micro controller which is re-programmable. AT89C51 89c51 is 8-bit device means it is capable of doing 8-bit operations.  It have 4 ports which are used as input or output according to your need. This device also have Timer, Serial Port interface and Interrupt controlling you can use these according to your need. The datasheet may be downloaded from...

pcb

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...
