In the transmitter circuit, as shown in fig.1, we measure the value of 3Axis accelerometer
(ADXL335)based on the hand movement and converted into digital with the help of ADC 0816. ADC converts
the data from sensor and proceeds to the microcontroller for further conversion. Microcontroller gets the hex
data from the accelerometer. LCD display the corresponding directions Messages i.e. Left for –X direction,
Right for +X direction, Forward for +Y direction, Back for –Y direction and Remaining any condition it will
stop. At the same time microcontroller gets the data and compare inside with pre-defined values. As we change
the position of hand, values are change automatically and corresponding messages are shown on the LCD.
