How to start working?

ADXL345 Accelerometer

The ADXL345 is a small, thin, low power,

3-axis MEMS accelerometer with high

resolution (13-bit) measurement at up

to +-16 g.

Digital output data is formatted as 16-

bit twos complement and is accessible

through either a SPI (3- or 4-wire) or I2C

digital interface.

Accelerometer Working

Accelerometer Calibration

Mathematics & Calculations

#calculation of tilt

roll = y/(math.sqrt(z*z + x*x))

rolldeg = math.atan(roll)*(180/(math.pi))

rolldeg = round(rolldeg,2)

pitch = x/(math.sqrt(z*z + y*y))

pitchdeg = math.atan(pitch)*(180/(math.pi))

pitchdeg = round(pitchdeg,2)

rollpitch = str(rolldeg) + " " + str(pitchdeg)

print rollpitch

Simulating Virtual Keys

LOGIC KEY CODE KEYBOARD

if input=='up': return 0x11 //KEY_w

elif input=='lt': return 0x1E //KEY_a

elif input=='rt': return 0x20 //KEY_d

elif input=='dn': return 0x1F //KEY_s

elif input=='sp': return 0x39 //KEY_space

elif input=='rc': return 0x9D //KEY_RCTRL

How to make Connection

Hardware Connection Using Ethernet & WiFi.

Software Connection Using Python Socket Connection.

SERVER.PY

IP=getAddrIP();

sock.bind((IP,1234))

result,addr=sock.recvfrom(16)

CLIENT.PY

import socket

server_address =('192.168.182.103',1234)

sock.connect(server_address)

Future Scope

Dedicated gesture control for blind humans to interact with

Computers.

Future Scope

Simulating mouse events to automate shooting & action games.

Future Scope

EEG Game Simulator Using RaspberryPi & BCI
