Interfacing Accelerometer to Arduino

In this article, we are going to interface the GY-521 accelerometer with Arduino. The GY-521 has an InvenSense MPU6050 chip which contains a 3-axis accelerometer and a 3-axis gyro meter. This makes it a 6 DOF IMU (6 degrees of freedom inertial measurement unit). The chip also includes a 16-bit analog to digital converter on each channel and a DMP (Digital Motion Processor) unit. The DMP unit is responsible ...

Home Automation using Arduino and GSM Module

In this  article, we are publishing a highly useful home application – GSM based home automation using Arduino. The project consists of a 16×2 LCD module for displaying the status of the home appliances. The status (turn ON or turn OFF) of the connected devices can be changed by sending an SMS from your mobile phone. Upon receiving SMS commands through GSM module, arduino will change the status (turn ON/OFF ...

Robot using Arduino and Bluetooth Module (Obstacle Avoidance Robot)

This project is designed to build a robot that automatically detects the obstacle on its path and guides itself whenever an obstacle comes ahead of it. This robotic vehicle is built, using Arduino UNO board. An ultrasonic sensor is used to detect any obstacle ahead of it. A motor driver IC and 2 DC motors are used for controlling the movement of the robot. A servo motor is also used in this project. The ult ...

Simple Infrared PWM on Arduino, Part 3 – Hex IR Signals

In Part 1 of this series, we demonstrated how to send signals using soft or Simple Infrared PWM on Arduino. In our Part 2 post we looked at sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal using soft PWM. We have since improved the PWM method shown in Part 1 Part 2 to provide better performance and improve portability. In this Part 3, we will take the ...
