In this tutorial, we are going to design an Arduino Uno based Robotic Arm from some cardboards and servo motors. Entire process of construction has been explained in detail below. Here in this project Arduino Uno is programmed to control servo motors which are serving as joints of Robotic arm. This setup also looks as a Robotic Crane or we can…
Nowadays, visual indication is a must-have feature for any electronic device, which will make user interaction much easier. There are multiple ways to implement the visual indication, from simple light indications to LCDs or even holograms. Today, we will be talking about such a device, which has been used in the industry for decades – the Seven Segment Display. The 7…
The biggest crisis we are heading into is climate change due to excessive use of fossil fuels, and to overcome these issues, we have only one solution, which is utilising Renewable Energy. Renewable energy is a type of energy that is harnessed from nature without causing ill effects to the environment. One of the most prominent kinds of renewable energy is…
A flex sensor is a low-cost, easy-to-use variable resistor that is designed to measure the amount of deflection it experiences when bent. The sensor's resistance is lowest when it's flat on the surface, increases when we bend it slowly and reaches its maximum when it's at a 90-degree angle.
Flex sensors are popular because they are used in many…
A digital pulse oximeter and heart rate sensor is an electronic device which can measure the heart rate of a person by measuring the difference between oxygen rich and oxygen less blood. Not only heart rate, this device can also measure the concentration of oxygen in blood. So in this article, we will interface the popular MAX30102 pulse oximeter and heart rate…
Adding sounds or music to our project will always make it looks cool and sounds much more attractive. Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra SD card module and a normal speaker. In this article I will show you how easy it is to Play music/add sound effects using…
