Chapter 3.4 - 8051 On Breadboard with Multiple Led Blinking-Practical Tutorial

Now Lets begin with the Practical tutorial. This is the most easy of all the practical tutorial and also the fast one. Just make sure you have all the 8 blue LED. 
(Note : We have not used resistor here, since the blue led is capable to handle voltage of over +5V if you are using other color, make sure you use a resistor of value 270 ohm else the led will get damaged.
If you have difficulty differentiating between anode and cathode, the look at the led, the flat large surface is cathode and the the leg with thing surface is Anode) 

1. Now place the negative end of  LED to Port 1.0 or Pin no 1 of 8051 Microcontroller and the +v pin to the +ve line in the breadboard. Make sure you have connected anode to +ve and cathode to pin no 1.

2. Now place the negative end of  LED to Port 1.1 or Pin no 1 of 8051 Microcontroller and the +v pin to the +ve line in the breadboard.

8. Now place the negative end of  LED to Port 1.7 or Pin no 1 of 8051 Microcontroller and the +v pin to the +ve line in the breadboard. And it will look like the following image. Thats it! this was the final stage of Practical tutorial. Now we have to do some programming to operate these LED. Jump to the next chapter to get the source code.
