Today we will learn a super practical and interesting little project – Control LED lights via a mobile app using Bluetooth module. This project will not only help you get familiar with the basic GPIO operations of Arduino but also let you understand the practical applications of Bluetooth communication. After completing the project, you can … Read more
The preliminary round of the RM campus competition has just passed. I wonder if everyone has been paying attention to it? For those who did not participate, there is no need to worry. Here is the most comprehensive tutorial on using the Bluetooth module. (Including the largest engineering drawing assignment ever) In the RM campus … Read more
The Bluetooth module is used for communication between Bluetooth devices. The most common use is for an Arduino to communicate with a smartphone via the Bluetooth module. 1. HC-06 (Slave) 1 Operating voltage: 3.3V LDO for the board, input voltage of 3.6~6V, current approximately 30mA when unpaired, about 10mA when paired. Do not exceed 7V … Read more
Controlling the LED indicator light with voice commands may seem like a challenging feature, but in reality, it is quite easy to implement. We can quickly achieve this by using an Arduino UNO development board in serial communication with the HC-06 Bluetooth module and a smartphone to send voice commands to the HC-06 Bluetooth module. … Read more
