Sending Sensor Data to Android Phone using Arduino and NRF24L01 over Bluetooth (BLE)

Here in this tutorial we will demonstrate how to send any data over BLE using nRF24L01. We will send temperature readings from DHT11 to smartphone using Arduino and nRF module over BLE.

#Project – #HC05 #Bluetooth Module Interfacing with #ESP8266 to Control an LED from #Android App: 

Arduino based Smart  Watch

So here we fetch some information from an Android mobile phone by using an android application and then send this information to OLED display by using Bluetooth Module and Arduino Pro Mini. Android smartphone already has inbuilt Bluetooth to send the data and at receiving end we have used Bluetooth module HC-06 with Arduino. Bluetooth module HC-05 can also be used in place of HC-06.

Bluetooth Controlled 8×8 LED Matrix Sign Board Display using Arduino

Make a Bluetooth controlled Sign board using an 8*8 Matrix display. A unique feature of this project is its android application which allows the user to control all the 64 LEDs individually from the mobile phone. This enables the user to create custom designs with ease and display it on the LED display.

How to Program Arduino with an Android device

You might have used OTG adaptor for connecting Pen drives and game controllers, and give power to small devices. You can do much more things other than powering up your Arduino board with Smart Phone. In this tutorial, we will compile and upload Arduino code using Android Application called “ArduinoDroid” which is completely same as Arduino IDE.

DIY Speedometer using Arduino and Processing Android App

In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added the option of charging your mobile phone as it displays your speed. Yes, you can also use this as a power bank for your mobiles on the go as the 18650 has high charge density and can easily be charged and discharged.

Voice Typing on 16×2 LCD using Raspberry Pi and Android App

In this project we will provide the input voice using Google Voice Keyboard via a Android App(BlueTerm) and print the text on 16×2 LCD using Raspberry Pi. Here we will type the text on 16×2 LCD using wireless Bluetooth Medium and will use USB Bluetooth dongle with Raspberry Pi. So basically we need interface the 16×2 LCD with Raspberry Pi and setup the Bluetooth in Raspberry Pi to receive the data sent by Mobile phone. 

Control Raspberry PI GPIO using Android

Raspberry Pi 3 has inbuilt Wi-Fi and Bluetooth, and Bluetooth is a very popular wireless communication Protocol. So today we are going to Control Raspberry Pi GPIO Pin through an Android app using Bluetooth.
