This kit Accelerometer based wireless Video Game is being designed to bring the RF technology. In this system we are using this technology to make a wireless remote through which has identity and can be used notify and define any person, object , gesture type (by type of tilt data) etc. The important technology used in this sensing the gesture basically the tilt using accelerometer (sensor which senses tilt and convert it into voltage variation in x y and z coordinates). Different sort of binary data is being generated on different tilt event. Here we used 5 different tilt conditions.
In the kit Accelerometer based wireless Video Game as we change the orientation of accelerometer, voltages at different pins of the accelerometer get changed, and hence we can convert these analog voltages into digital voltages only by using comparators. By using 4 comparators in inverting and non inverting mode, we get 4 bit of unique data at different orientation. This 4 bit of data is encoded by the encoder HT12E and given to RF transmitter which transmits the data wirelessly.
In the kit Accelerometer based wireless Video Game at receiver, the data is received by RF received and given to decoder HT12D. The decoder decodes the data in 4 bits format and gives it to the microcontroller, the microcontroller gives this data to computer and hence the game is controlled. Here we have used a snake game which has been developed in VB6.0 and our interfacing is also in the same software serially.
