Hello friends, I hope you all are doing great. In today's tutorial, I am going to explain the Relay Interfacing with Microcontroller using ULN2003A. In the previous lecture, we have discussed the detailed Introduction to Relay along with its working. Now we are going to practically interface the relay with a microcontroller to design an automatic switch. Relay is a key component in almost every electronic circuit. It can be
used as a switch and can also be used as a voltage regulator.The microcontroller I am going to use here is PIC18F4552 but you can use any other Microcontroller. You just need to change the syntax of coding but the logic will remain the same. Here, I am using ULN2003A to control the relay and from this relay, we can control anything.So, let's get started:
Relay Inte ...
Hello friends , I hope you all are fine and enjoying good health. In today's tutorial, I am going to design an LED Blinking Project using PIC16F877a. In the previous chapters, we have seen all the basics of PIC Microcontroller and now we are ready to design our first project on PIC Microcontroller.
Its a very simple project so the programming level is very basic. We will just add some LEDs on all pins of PortB of PIC16F877a and then we will program it in such a way that these LEDs will blink in different pattern, we can also change the speed of blinking by adding a delay.
I will explain the whole code but if you got any problem may ask in comments.I will recommend you guys to do this project, I know a beginner can't make this project work in firs ...
