arduino Nano -based Bluetooth billboard using an arduino nano microcontroller, 0.96" OLED Display (SPI/I2C, 128x64), and an HC-05 Bluetooth module. The code allows the billboard to receive messages ...

Creating a Bluetooth-controlled device with an Arduino Uno and an HC-05 Bluetooth module enables control of lights or even relays to manage AC appliances wirelessly using an Android smartphone.

This project establishes communication between the HC-05 Bluetooth module and the PIC16F887 microcontroller using UART. It enables wireless data exchange, allowing the microcontroller to communicate ...

“Which came first, the chicken or the egg?” Don’t bother us with stupid questions, they both co-evolved into the forms that we now serve up in tasty sandwiches or omelets, respectively. “Which came ...
