Could you tell me something spy robots?

SPY-robot works on the following principle which uses the modulation technique using the RF module 433.95Mhz operating frequency. The module is used to transmit data from the transmitter module accepted from the platform switch on the transmitting end. The receiver module to stay in the spy-robot receives the data transmitted. The data received is useful for the engine as per the requirement, and performing various operations on the basis of the address used by the encoder and decoder according to the received data.

Each switch in the switch platform is assigned a different function. When the user presses a particular switch, for example, if "x" is pressed the data associated with that change will be recognized by the matrix of CI 74922 that is directly connected to the switch platform.

The data will be even more since the encoder IC HT12E, the encoder IC is one of the most important and diverse part of the Robot, the data transmitted from the switch-key pad connected to the encoder IC74922 reach the address / data multiplexed pin of the encoder IC HT12E. As soon as data is received, then through the encoder output pin of IC data given to the transmitter unit RF Module. From there the data is transmitted outdoors.At the receiving end of the data are collected by the receiver and the intended task is performed and the need is filled completely. HT12E here encoder IC plays an important role in the encoding of the data required for the intended task. Once the switch is pressed the data is given to the key encoder IC74922 where data are collected by the new HT12E and from there the data is converted to digital serial format and transmitted. The encoder IC both have a lot of work throughout the project and are treated as one of the most important part of the project.
