DC Motor Speed Control using GY 521 Gyro/Accelerometer and Arduino

jojo August 3, 2017 No Comments
In this article, we are going to control two motors by using the GY-521 accelerometer module. The speed of the motor will increase or decrease upon moving the GY-521 module up or down. On moving the Gy-521 towards the downside, the speed of the first motor will decrease and the speed of the other motor will increase; while on moving the GY-521 towards the upward side, the speed of the second motor will decrease and the speed of the first...

Smart LCD Brightness Control using Arduino and LDR

jojo July 4, 2017 No Comments
Smart LCD  with Automatic Brightness Adjusting Using Arduino and LDR Sensor Here is a simple Arduino project that focuses on adjusting the brightness of an LCD screen whenever there isn’t  sufficient light in a room. The Arduino reads the surrounding light intensity using an LDR sensor.  The room temperature and humidity range will also be displayed on the LCD. The entire hardware of this simple project using Arduino can be divided into three parts. The sensors, Arduino board, and the...

Robot using Arduino and Bluetooth Module (Obstacle Avoidance Robot)

jojo April 27, 2017 4 Comments
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 ultrasonic sensor is then mounted...

Arduino Irrigation and Plant Watering using Soil Moisture Sensor

jojo April 10, 2017 1 Comment
Automattic Irrigation and Plant Watering System using Arduino and Soil Moisture Sensor This project is about a moisture-sensing automatic plant watering system using Arduino UNO. The system reads the moisture content of the soil using soil moisture sensor and switches ON the motor when the moisture is below the set limit. When the moisture level rises above the set point, the system switches off the pump.  The status of the tank, motor and the moisture level will be displayed...

Home Automation using Arduino and GSM Module

Shone V.J April 7, 2017 13 Comments
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) of the device that is mentioned in the SMS. Objectives...

Interfacing Accelerometer to Arduino

jojo April 4, 2017 1 Comment
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 for combining the raw data and performing some calculations to remove...
