By combining the power of ESP32, the versatility of Google Firebase, and the simplicity of MIT App Inventor, we will create an IoT web app that displays sensor readings … Read more
In this tutorial, we will learn to interface HC-05 Bluetooth module with STM32 Blue Pill using STM32CubeIDE and HAL libraries. We will use an android application to communicate with the STM32 Blue Pill through the HC-05 Bluetooth module. We will see an example to control an LED from the Android application using Bluetooth communication. The … Read more
In this tutorial, we will learn how to build an android app that will control the outputs of ESP32 over WiFi and internet using an Android App. We will control the output GPIO pins of the ESP32 module by toggling the two LEDs connected with the GPIO pins of the module. This android app will … Read more
In this tutorial, we will learn how to build an android app with a slider that will enable us to control the brightness of an LED connected with Arduino. The slider will be moved to set the slider value. In response, this slider value will set the duty cycle of the PWM signal generated by … Read more
In this user guide, we will learn to build an RGB LED Control Android App with MIT App Inventor and control it using Arduino. This Andriod app will allow us to change the color of an RGB LED by setting it from a color picker featured on the application screen. The transmission of RGB values … Read more
In this user guide, we will learn to build an Android App using MIT App Inventor and display temperature readings acquired from DS18B20 sensor with Arduino. The transmission of sensor data will be through the HC-05 Bluetooth module. Our Android application will display sensor readings on our smartphones. The sensor readings could be accessed anywhere … Read more
In this tutorial, we will learn how to send sensor readings to an Android phone using Arduino nRF24L01+ module, and BLE. The transfer of data will be through Bluetooth Low Energy (BLE). We will use DHT22 sensor to access current temperature readings and send them to our android phone using nRF24L01+ RF module that we … Read more
In this tutorial, we will learn about HC-05 Bluetooth to serial port module and how to interface it with ESP8266 NodeMCU. This Bluetooth device operates on UART communication. In other words, it uses serial communication to transmit and receive data serially over standard Bluetooth radio frequency. Therefore, we will use TX, RX pins of ESP8266 … Read more
In this user guide, we will learn to send sensor readings to Google firebase and also on Android app through Google Firebase using ESP8266 NodeMCU and Arduino IDE. We will make our personal ESP8266 IOT app by using Google Firebase and MIT App Inventor. Previously, we used the Blynk application to control ESP32’s output (Control … Read more
In this Arduino project, we will create a home automation system that will control home appliances via HC-05 Bluetooth and an Android application. HC-05 Bluetooth will be used to communicate with Arduino using an Android Application known as the S2 Terminal. There are also other apps but this is free and easy to use. To … Read more
