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…
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…
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…
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…
In this project we see how to make a Bluetooth speaker with a clock. It displays date, time, temperature and humidity and it is updated from Internet at 15 minute intervals. It also has a 32-band audio spectrum analyzer that displays different musical patterns. The clock or spectrum analyzer can be displayed while playing music….
With this device you will be able to read the measurements made by a DIY multimeter directly on your glasses. No cables will be present as the multimeter will send the read data through the Bluetooth connection. For reasons of compactness a PCB has been designed but it is possible to do it directly using…
In this project we will see how a machine was built that takes out your tea bag when the previously set time expires. The Steampunk-style structure was built with 4mm plywood cut out using a laser engraver. As for the electronics, there is an Arduino Nano that controls a servo motor after the set time…
This project allows you to create a low cost GPS data logger for RC aircraft. A Data Logger allows you to record data from sensors and save them in a micro SD memory. In this case, data from a GPS module will be recorded. During the flight, an Arduino Nano will receive data from a…
In this article we will see how to build a fire and gas detection system that also provides protection. We use Arduino Nano as a microcontroller and two sensors: MQ-2 gas sensor and the flame sensor. We use a 16×2 LCD display to view live status. There are also PCB designed dual channel relays to…
This project is not only an intelligent coffee machine with smartphone control but also allows you to graphically view the temperature trend. It can be controlled via Bluetooth or simply fill up with fresh water and the system starts automatically! Developed on Arduino Nano, it uses an ST7920 display, an HC-05 Bluetooth module, a Dallas…
In this project we will see how to make an RC controller that communicates using a 2.4 GHz radio signal. This RC controller was designed to be used with a quadcopter. The radio control was made in 3D and uses an Arduino Nano that sends, through an NRF24L01 module, the data read by two analog…
