galism 4:caab577334f0 1 /* Senior Project Bluetooth bicycle speedometer
galism 4:caab577334f0 2 Author: Michael Galis
galism 4:caab577334f0 3 This is the main file, it implements both Acceleration Service and Reed Switch
galism 4:caab577334f0 4 Service to send all the necessary data over bluetooth in organized packages.
galism 4:caab577334f0 5 Also there is code to reed from the accelerometer over an I2C connection.
