We have previously made many Bluetooth projects using HC-05 and ... is given at Arduino serial monitor and it will send them to HC05. First of all, connect the components as per circuit diagram below.

An Android App for Connecting to HC-05 Arduino Bluetooth Module and controling a 16x2 character display and a DS1307 RTC Module connected to the Arduino ...

Controlled by a smartphone app, a cheap Arduino board with an HC-05 Bluetooth module ran the show. However, when this was all assembled, the car was too heavy to climb walls or stick to the ceiling.

This circuit uses Arduino board that accepts data via HC-05 Bluetooth module from various types of gadgets like Android based smartphones. Arduino is the heart of this programmable display. The ...

The HC-05, a Bluetooth to serial bridge, can be found for around $5 on the internet and therefore may be the cheapest way to add Bluetooth connectivity to your project. However, its default ...

Therefore, we will only work in operating mode. Circuit diagram to connect HC-05 Bluetooth Module with TI-MSP340 Board is shown below. Here, we have done 4 connections from HC-05. The RxD and TxD pins ...
