I intend to use the below IR break beam sensor
As you can see in the above picture, 5V power pin is already occupied by one of the wires of IR break beam sensor.
The bluetooth module that i currently have ( HC05 ) requires 5V input voltage. Since 5V pin is already occupied by the IR break beam sensor , i am left with option to use the 3.3 V pin of the Arduino.
What Bluetooth module do you recommend which requires input power of max 3.3 V and can be used along with Break Beam sensor ?
