Serial Bluetooth Module (Master/Slave) sweep hand The speed of the motor

The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied

Serial Bluetooth Module (Master/Slave) sweep hand The speed of the motorThis serial bluetooth module can work as either master or slave. This module also includes the base board, not only the core board, most functions are pre set, so only the serial port communication is available but its more easy to use. It can be used also with arduino or Microcontroller. Features Use CSR popular buletooth chip, bluetooth V2. 0 Protocol standard. Serial port operation voltage 3. 3V Baud rate set at 9600, but you can change it with AT
