How To Make Android App To Connect Arduino via Bluetooth

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, and motor, and read the temperature-humidity of the environment. We will use a free MIT App Inventor website for building apps via blocks. We will give all the project files for this project. If you are ready let’s get started. Schematic Firstly we made an example circuit to make bidirectional communication. You can see in the picture below which components we use. The main component is Arduino Nano which controls the system. We connect the red LED to the D2 pin. We use the L293D motor driver to control the DC motor. We added AHT10 to get temperature and humidity from the environment. Finally, we added HC-05 to communicate with the Android App. Circuit Schematic Android App We made an Android App via MIT App Inventor which is easy to make basic apps. This app will get and send data via Bluetooth. Let’s start to explain what we did. App

Ultrasonic Sensor HC-SR04 With PIC Microcontroller

How Ultrasonic Sensor Works 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 pins. For showing distance, we used an LCD.

Write Strings to LCD With Two Buttons

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 the 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. LCD Interfacing with PIC Using XC8

LCD Interfacing with PIC Using XC8

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.

How to Make Blink LED with PIC16F628A

How to Make Blink LED With PIC16F628A 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.

DC Motor Speed Control With PIC16F628A

DC Motor Speed Control Simulation In this project, we will control the speed and direction of a DC motor using the PIC16F628A microcontroller. We will write the software in MPLAB IDE with the XC8 language that will send a PWM signal to L293D to control the motor. Finally, we will simulate it through the Proteus software. PWM (Pulse Width Modulation) You can get more information about the PWM signal from the link above. Now let’s examine the L293D motor driver.
