In this project, we are going to make an Android App that will connect with Arduino Nano via the HC-05 Bluetooth module. This app will control the LED, motor, and read the temperature-humidity of the environment. We will use a free MIT App Inventor website for building app via blocks. We will give all the project files for this project. If you are ready let’s get started.
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 tutorial, we are going to teach how to use an LCD display with an 8-bit PIC microcontroller. We will give you a powerful LCD library and explain how to use it in your microcontroller in this tutorial. We will do examples on the PIC16F628A microcontroller but you can do small changes to use it in your projects. Let’s get started to make LCD Interfacing.
