Pedo Meter Using Ardunio Mega

Pedometers are the devices that only used to count footsteps. This Pedometer will count the number of footsteps and display them on a 16×2 LCD module. Adx;335 is interfced with Arduino Mega.

The ADXL335 is a complete 3-axis Analog accelerometer, and it works on the principle of capacitive sensing. It is a small, thin, low power module with a polysilicon surface-micro machined sensor and signals conditioning circuitry. ADXL335 accelerometer can measure the static as well as dynamic acceleration. Here in this Arduino Pedometer project, the ADXL335 accelerometer will act as a Pedometer sensor.

An Accelerometer is a device which can convert acceleration in any direction to its respective variable voltage. This is accomplished by using capacitors (refer image), as the Accel moves, the capacitor present inside it, will also undergo changes (refer image) based on the movement, since the capacitance is varied, a variable voltage can also be obtained.
