It's a 28 pin IC which can be very easily and quickly configured for getting the required results by adding a handful of common passive electronic components. For example pin 28 and pin 27 are assigned as the trigger inputs for initiating playback and recording functions.

The IC also has appropriate visual indication options which provide the user with instant information regarding the position of the circuit. The LED at pin 8 indicates the end of a playback file session.

WSN and GSM based Remote Home Security System

The LED at pin 10 stays illuminated for so long the audio is being played, indicating circuit "busy" The LED at pin 22 indicates through rapid flashes regarding the playback or recording modes of the IC. The input data is normally picked from the mic which is appropriately connected across the pins 17 and 18 of the IC.

The sampling rate or the frequency response is limited to just 8 kHz max that's pretty ordinary if we compare it with the specs of modern Hi-Fi equipment.

The biosignal to a road traffic accident or damage to the brain due approach usually requires user calibrations because to a brain hemorrhage or a tumor.

Paralysis can also biosignals produced by each individual is unique due results from motor neuron diseases [2]. Most of the time the life led by these peoples are II. Materials and Method.

Different techniques by rehabilitation 2. Flex Sensors: An ideal rehabilitation aid helps in collecting Flex Sensors or Bend Sensors are a type of information from the surroundings, analyze this variable resisters which change their resistance when information, convey this information to the user and it is bent from one end.

The resistance of the flex finally receive commands from user. With the sensor changes when the metal pads are on the advance in current research in image and signal outside of the bend text on inside of bend.

The Flat www. So the flexion should occur towards the distal Fig 2.

Significant features of this microcontroller include six analog input ports A0 — A5 , a 5V and 3. It can be interface with computer using the USB cord[5]. One salient feature is that the recorded sound is retained even after power supply is removed from the module.

Voice/Audio Recorder Playback Circuits

APR pin diagram is shown in Fig. Pins 1 through 6 and 8 and 9 are used to record 8 different audio messages M1 — M8. They were mounted on 5 fingers of a glove as indicated in Fig. They captured specific flexion movements of the fingers and based on the change of resistance of different sets of sensors, the system was trained to switch to different modes of operation. Arduino Uno was used to record the changes in resistance of the flex sensors on bending.

The recording was done through 5 analog input ports. Based on the program ported on the microcontroller, signals were sent as digital output to either the APR Voice Module, or the Wheelchair Control Module. Flex Sensors mounted glove and default unflexed state and flexed middle finger.

Assembling the whole system was done by first Sensor 5, thumb, AI 5.Every set of flexing action of the fingers were checked and monitoring of the respective reaction of the system was also done.

Next Message: The logo of our development team was included on it, we also considered slots for the volume controller, some of the input push-buttons, the two tactile membranes, the speaker, the graphic display, and the keyboard buttons.

Tests were conducted to verify the interaction of these stages. Gnaneshwari Yadav. The sampling rate of the IC can be set as per the user preference.

The pulse must be low for least cycles of the sampling. This pin in Option: The device returns to the.
