LED Blinking using 8051 Microcontroller

LED is a semiconductor device used in many electronic devices, mostly used for indication purposes. It is used widely as indicator during test for checking the validity of results at different stages.

It is very cheap and easily available in variety of shape, color and size. The LEDs are also used in designing of message display boards and traffic control signal lights etc.

Consider the Proteus Software based simulation of LED blinking using 8051 Microcontroller is shown below:-

In above Proteus based simulation the LEDs are interfaced to the PORT0 of the 8051 microcontroller.

Let's see the Embedded C Program for generating the LED output sequence as shown below:
