Story In this tutorial I am going to show you how to build a Voltmeter with a big Nokia 5110 LCD display using Arduino. Building a voltmeter is a great learning experience. When you finish building this project, you will have a better understanding of how voltmeters work, you will refresh your knowledge of Ohms […]

Story When you measure distance between two point general way is to use a ruler. But you can use a lot of other ways: by laser, map, foot or walking meter. The walking meter is very useful when you are measuring curved (not straight) distance. But it might be very tired because you should walk

Story Imagine you could administer remotely your water utility service in real time, turning on or off your water services according to your usage patterns or needs, and not just letting the water flow in all the time, you could prevent taps for leaking a single drop per one faucet per one home leaking wastes

A while back we wrote an article on sensing orientation with the adxl335 accelerometer. In that article I mentioned all the drawbacks of trying to do this with just an accelerometer, and said that if you needed something stable, what you really needed was an IMU. Well… We are back with an article covering just
Stable Orientation – Digital IMU 6DOF + Arduino Continue Reading
One of the first articles we did was on the hmc6352 digital compass. Well this is his older brother (or younger but smarter). I really don’t know what to say about the HMC5883L other than it is a three axis magnetometer, so it is capable of sensing in 3 directions. That doesn’t mean that it
Triple Axis Magnetometer HMC5883L + Arduino Continue Reading
This article is about a simple three digit digital thermometer using arduino. Range of this thermometer is from 0°C to 99.9°C. There is also a provision for displaying the temperature in °F scale. Three terminal analog temperature sensor LM35 is used as the sensor here. LM35 can measure temperatures between -55°C to +155°C. The supply

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

Today we are going to Measure the Weight by interfacing Load Cell and HX711 Weight Sensor with Arduino. We have seen weight machines at many shops, where machine displays the weight just by placing any item on the weighing platform. So here we are building the same Weighing machine by using Arduino and Load cells,

Thermometers are useful apparatus being used since long time for temperature measurement. In this project we have made an Arduino based digital thermometer to display the current ambient temperature and temperature changes on a LCD unit in real time . It can be deployed in houses, offices, industries etc. to measure the temperature. This project is based on Arduino
