Description The 74HCprovides provides six independent inverters with open drain outputs. The device is designed for operation with a power supply range of 2. As a master As a master device, it will search the last paired salve device until the connection is built. The ranging accuracy can reach to 3mm and effectual angle is 15°.

Bluetooth HC -with serial port module. HC - module has two modes, Data mode: Exchange of data between devices. In this case, the only time you need to be concerned is if the device outputting into the HC - is not 3. I am trying to connect my bluetooth module to my Arduino but it takes 3. HC - , The Arduino mega takes 5v) and the tutorials online say to connect the RX pin to the Ground through a voltage divider. Default settings such as the device name can be changed from ‘ HC - ’ to something else, specially when two or more HC - are used in the same area. When looking for an HC - to use with this exercise, and the HClibrary , watch carefully to make sure that the device offered is the HC - , which is programmable as master or a slave, and not the HC -which can only be one or the other.
