Complete connections are given in the below table: Arduino Nano SCL & SDA pins of the I2C module are connected to A5 and A4 pins of Arduino Nano, respectively. To interface 16x2 LCD modules with Arduino, we are using the I2C module.

X, Y, and Z pins of the accelerometer are connected with Analog pins (A1, A2 & A3) of Arduino Nano. In this circuit, we are interfacing with Arduino Nano with ADX元35 Accelerometer. Circuit DiagramĬircuit Diagram for Arduino Accelerometer Step Counter is given below.

We build many projects using Accelerometer ADX元35 including Gesture controlled robot, Earthquake Detector Alarm, Ping Pong Game, etc. ST- This pin used for set sensitivity of sensor.Z-OUT- This pin gives an Analog Output in z direction.Y-OUT- This pin give an Analog Output in y direction.X-OUT- This pin gives an Analog output in x direction.Vcc- 5 volt supply should connect at this pin.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.īelow are the images for Accelerometer from the front and back side along with the pin description. Here in this Arduino Pedometer project, the ADX元35 accelerometer will act as a Pedometer sensor.Īn Accelerometer is a device which can convert acceleration in any direction to its respective variable voltage. ADX元35 accelerometer can measure the static as well as dynamic acceleration. It is a small, thin, low power module with a polysilicon surface-micro machined sensor and signals conditioning circuitry. The ADX元35 is a complete 3-axis Analog accelerometer, and it works on the principle of capacitive sensing. This pedometer can be integrated with this Arduino Smart Watch. This Pedometer will count the number of footsteps and display them on a 16x2 LCD module. So in this tutorial, we are going to build an easy and cheap DIY Pedometer using Arduino and accelerometer. Pedometers are the devices that only used to count footsteps. We have also built an IoT Based Patient Monitoring System where the critical data have been sent to ThingSpeak to be monitored from anywhere.

And these IoT devices are synced with the cloud so that you can easily get all the history of your physical activity on a smartphone.

Fitness bands are getting very popular nowadays, which not only counts the footsteps but also tracks your calories burned, display heartbeat rate, showtime and many more.
