Best Arduino Bluetooth-Controlled Projects
Now that you have an idea of what Arduino and Bluetooth-Controlled projects are, let’s look at some of the best projects you can make using this combination. In this section, we’ll show you some of the most popular projects and give you ideas for your own.
Bluetooth Controlled Car using Arduino
With this project, you can have complete control over your car with the help of Bluetooth and Arduino. This project relies on a car, Arduino board, smartphone, Li-ion Battery SparkFun Dual H-Bridge motor drivers L298 and LED for its construction.
You can create a simple Bluetooth-based remote control car using the components mentioned above. First, prepare the car by mounting the Arduino and motor drivers on it. Next, establish a circuit for connecting all the components to create a simple power supply system. After that, install your smartphone onto the car and use an app to connect it with the Arduino board via Bluetooth. Finally, write down some code in the Arduino IDE and upload it to your board.
There are plenty of tutorials available online on how to build Bluetooth controlled cars using Arduino. However, if you are facing any issues during the construction process, here are some tips to keep in mind:
- Use an appropriate Li-ion Battery that can power up both the motors and Arduino board simultaneously.
- Try to use a small car for this project since it will be easier to control and maneuver.
- Make sure your smartphone app is compatible with your Arduino Board before connecting them together via Bluetooth.
- Make sure your code matches the hardware setup of the car so it can perform its functions properly.
- Test out the car after completing each step of building it before assembling all components together. This will help you find potential problems early on and makes it easier to debug.
You also can use nearly any car chassis provided it can fit all the components and also can reach high speeds. Once you have completed the construction process, you can provide more functionality to your Bluetooth-controlled car such as adding lights and sensors for obstacle navigation. Have fun!
Arduino Bluetooth LED Control System
Another popular Arduino project is creating an LED control system using Bluetooth. This project can be used to turn on, off and dim LEDs from your Android smartphone or tablet.
To get started, you will need the following components:
- Bluetooth module HC 05/06
- Android application
- Arduino UNO
Basically, a Bluetooth platform to an android application, you can conveniently send instructions directly to hardware modules. On receiving data as “1” the LED blinks and turns off when it’s “0”. This Arduino project is simple yet useful, and requires very few components.
Smartphone-Controlled Arduino 4WD Robot Car
We already covered a Bluetooth controlled car before, this time we will create one that you can control with an Android app.
This project will require:
- Arduino UNO
- HC-06 Bluetooth Module
- 4WD Smart Robot Car Chassis Kit
- SparkFun Dual H-Bridge motor drivers L298
- LED (generic)×4
- Resistor 221 ohm
We can start by connecting the Arduino, motor drivers and HC-06 Bluetooth module as described in our previous guide.
Next, we need to create an Android App that will communicate with the HC-06 Bluetooth Module. This can be done using MIT’s App Inventor 2 platform. With this tool you can design your app by dragging and dropping components into place via a graphical user interface (GUI). The app needs to contain seven different buttons: forward, back, left turn, right turn, stop, increase speed and decrease speed. Each of these buttons should send out a unique character string when pressed which will be used by our Arduino code to move the robot car accordingly.
Once the app is designed and working with the Bluetooth module, we can write the Arduino code to control the robot car. The code should look for a character string from the Bluetooth module, and perform an action based on which button was pressed in the Android app. We can use if-statements to detect which character string is being sent and then move the robot accordingly.
Finally, we can add some additional features such as LED light effects that change when you press each button or a buzzer to indicate when your command has been received.
With this setup, you will be able to control your own 4WD Robot Car using a smartphone!
Autonomous “Follow Me” Cooler Using Arduino
This project is a cool way to show off your Arduino Bluetooth-Controlled skills! It involves creating an autonomous “Follow Me” cooler that will follow you around. The idea here is that the cooler is equipped with a Bluetooth receiver and motors, which can be controlled from a smartphone app.
To get started on this project, you will need some basic items: an Arduino board, motors for the wheels of the cooler, a Bluetooth module or shield, and some mounting hardware for attaching everything together. You will also need an appropriate power source for your device – either batteries or an AC adapter.
Once you have all of these components gathered together and connected, you’ll want to begin programming your Arduino board. You will need to decide on the logic for your device – how it will follow you around and when it should start/stop emitting air. This can be done using Arduino’s “if” statements and programming language.
Next, you will want to use a smartphone app that will allow you to control the cooler from a distance. This app should have features such as starting and stopping the cooler, setting temperature levels, and coordinating the movements of the cooler with GPS data. Once this is complete, you’ll be ready to give your autonomous “Follow Me” cooler a test run!
A Glove That Translates Sign Language Into Text and Speech
A glove that translates sign language into text and speech is an Arduino Bluetooth-controlled project that can be quite useful for people who are deaf or hard of hearing. To build such a project, you will need the following components:
- Arduino Nano R3;
- Bluetooth Module;
Utilizing an accelerometer, we can measure the tilt of a hand. To accomplish this, five bend sensors are placed on a glove – four for each finger and one for the thumb. By leveraging sensors to measure the bend in each finger, thumb, and palm of a user’s hand, the Arduino Nano microcontroller is able to interpret which set of values correspond with which symbol. Once this data is received by an Android app via Bluetooth connection, it displays and speaks symbols that were generated accordingly.
How to control LEDs using Bluetooth Arduino?
To start the project, it’s necessary to connect the Bluetooth module to your Arduino board. Once connected, you can use an Android device (or other compatible device) to send data that will control the LED on your Arduino board.
To program the Arduino board, you’ll need to upload a sketch that sets up a serial port connection with your device and then defines how it should react when certain data is received from your device. When specific data is sent from your device such as “1” or “0”, the Arduino board will use this to decide whether or not to turn on the LED.
There are tons of online tutorials and resources that can help you get started with this project. Once it is set up, you will be able to control the LED on your Arduino board from anywhere in the world!
