DIY Arduino Wireless Programming Shield using Bluetooth Module
While doing projects using Arduino, we always need to connect Arduino to PC in order to upload the program in it. But sometimes it is very uncomfortable to always connect the board with PC as if it is a robotics project then you always have to move the robot near to labtop to re-program it. This problem can be solved by programming the Arduino wirelessly. So here we are building a circuit to program the Arduino wirelessly using Bluetooth module HC-05.

Arduino HM-10 BLE Module Tutorial

The HM10 has become a very popular Bluetooth 4.0 BLE module. The HM10 is a Bluetooth 4.0 based module only, so it will not connect with Bluetooth 2/2.1 module such as HC-05, HC-06 and other Bluetooth modules. The HM10 is controlled via AT commands sent over the serial UART connection. HM-10 is a Bluetooth Low Energy (BLE) module, to know more about this module, check out the HM-10 BLE datasheet

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.

ESP32 BLE Server – GATT Service for Battery Level Indication

Wireless Headphones, Fitness bands, Bluetooth Speakers, In-Ear headphones, Mobile phones, Laptops… there are so many Bluetooth devices around us and most of these devices are battery operated. Have you ever wondered that, when you connect a Bluetooth device to your mobile phone how it automatically understands that the connected device is a computer or audio device or a mobile phone? For some devices our phone might even automatically shows the battery percentage of the connected device on the notification bar. How does all this happen on their own? There should be some common protocol shared between the phone and the Bluetooth device right!

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.

Interfacing HC-05 Bluetooth module with AVR Microcontroller

In this tutorial let us learn How to interface HC-05 Bluetooth Module with AVR ATmega8 microcontroller. We will establish communication between Android mobile and Atmega8 through Bluetooth module which takes place through UART serial communication protocol. In this project we will control a LED using Bluetooth of our smartphone.
