Work with DDS AD9850 from script VBS

VBS script designed to directly enter the frequency of the output signal of the numeric keys '0..9' on the keypad and sending commands to the COM port with voice. The marker button start and end of the input assigned to the key 'Q'.

Interaction with the DDS goes through the module Arduino Nano via the serial interface over USB (or Bluetooth or Wi-Fi over UART). Thanks to the module also becomes possible battery life DDS, because saving and restoring settings by using basic chip EEPROM ATMega328P.
