i have designed a Radio Frequency Detector it detects the mobile signals the output has been shown through an LED , now i have checked the circuit with 9 volts battery it is working properly , but i want to connect it with computer , any suggestion ???
i m thinking to connect it with a USB connector but , as i have searched there are 4 types of wires in USB connector cable , Positive voltage (V cc) , GROUND , DATA + & DATA - , actually i am unable to understand what is meant by DATA + & DATA - & which wires should be connected with data + and - ????
