It monitors electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and an absorption detector board. First instalment. Monitoring the electricity consumption of your home or business is an increasingly topical issue. The electrical measurements made,…
With Arduino Mega, we create, a keyboard with RFID module, a configurable access control system, to manage electric locks. In the market there are different types of controls for electric locks: from the simple insertion of codes to biometric readers, passing through transponder readers (RFID) or magnetic strips. The project that we present…
We are used to seeing clocks with 7-segment displays which, through the switching on and off of some LEDs, form the numbers. This project is different, in fact instead of the LEDs we find stepper motors that, by setting the rods in motion, allow the visualization of the numbers as if it were a classic…
https://youtu.be/KVFvDvqkmQU I created a device using liquid lenses allowing for the glasses to change its prescription. Because of this ability, these glasses can determine an individual’s prescription and change to correct vision for different prescriptions. This device eliminates the need for progressive/bifocal lenses and yearly eyeglass/contact replacements. More info
This project is about making Smart System using BoltIOT kit which will send the notification via SMS automatically (send by system) to house owner when the intensity of Sunlight increase or decreases, So they will easily turn ON/OFF the out side lights of the house with the help of Smartphone. if any delay in turning…
The project was born with the purpose of helping the deaf community to communicate and interact easily with the surrounding environment. The goal is to convert the basic symbols representing the 26 letters of English alphabet and display them on a smartphone screen. For this system we were inspired by the idea of controlling a…
Arduino-powered quadrupedal robots are fairly common designs for hobbyists to build once they’ve gotten a little more comfortable with embedded systems. A problem with many of the pre-designed quad platforms is that they take a long time to assemble due to their large size. This is what inspired Technovation to create their own quadrupedal micro…
Today is the world of internet social networks. We have many social platforms E-mail, Facebook, Instagram, Twitter and so on. For security reasons we should not use the same password for these platforms and some platforms require us to create passwords that are difficult to remember. It is better to write it down in your…
Beer Pong and its derivatives are some of the most popular games on college campuses, but they aren’t all that exciting with just a few cups at the ends of a plastic folding table. Meet the interactive table tennis table, created by Instructables user boregan1. It features a fully customized board game experience with a…
In this project we will see how to create an audio spectrum analyzer using a ferromagnetic liquid from a bottle filled with this particular liquid. To do this, an Arduino Nano will be used and an MSGEQ7 integrated circuit that allows you to read the audio peak of a given band. In this way the…
Can we “listen” a difference between pouring hot and cold water? As you see in the video you can do it, but why? It is mentioned that the change is due to complex fluid dynamics reasons. Beyond the scientific investigation, the question we asked ourselves was: is this ability to “listen to temperatures” something that…
The seismometer is a device for detecting earthquakes and measuring their strength. Generally these are very accurate tools and are relatively difficult to build at home. Commercially available sensors are often expensive, and inexpensive shock-sensitive electronic modules are not accurate enough for this purpose. In this project we will see how to create a cheap…
