An ultrasonic sensor is a very useful sensor that measures distances with sounds. We used the PIC16F628A microcontroller for this project. This microcontroller has TMR1 which we are going to use. We need 2 I/O pins for TRIG and ECHO pin. For showing distance, we used an LCD. For more information about the LCD library and usage click button below.
In this project, we are going to write strings to an LCD display with two buttons. The first button will change the position of the cursor and the second button will change character. In this way, you can write the strings that you want. For this project, we are going to use the PIC16F628A microcontroller and XC8 compiler. To understand how can we write to LCD display click the link below and read the tutorial.
In this project tutorial, we are going to make blink led projects with a pic microcontroller. After you read this tutorial you can build a PIC microcontroller project with XC8 on MPLAB IDE. We are going to make 3 different blinking projects. These projects are basic. Just learn how to make a basic project with a PIC microcontroller. You can see below which projects we are going to make;
- Blinking LED with 1s delay,
- LED with button,
- Blinking LED with a button.
In this article, we will tell you how to operate a 7-segment display (7SD in short) with a microcontroller. There are two (perhaps more) options to do this. The first is to connect the 7SD directly to the output ports of the microcontroller as shown in the picture above. This may cause a port shortage in large projects. As a second way to avoid this; We can run it by connecting a decoder to the 7SD. We will show both for you.
