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…
This robot translates Twitter activity into Cocktails of different flavors. When you want a cocktail, the machine will search for the latest five messages around the world mentioning one of the available ingredients. These messages define the composition of the drink and not only will the result be unique, but the cocktail recipe will also…
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…
This IoT home automation project allows you to have full control of your blinds from anywhere with the use of a photoresistor, a motor and a smartphone, you can adjust the blinds without actually having to get up. As for the assembly it is necessary to insert the servo in the curtains in order to…
In the age of Zoom, Messenger and Snapchat calls, communication around the world has become commonplace. But what if you could go back in time and painstakingly write the message one beep at a time? With this WiFi telegraph you can do it! Not many components are needed; essential is the ESP8266 module. We decided…
In this project we transform the M5StickC board into a laser rangefinder to accurately measure distances up to 2 meters. For this we need the ToF HAT (Time-of-Flight) sensor together with the M5StickC. In addition to displaying the distance, the software can also transmit the measured value to other devices via Bluetooth. In this way,…
Anyone can learn robotics, but what if there was a practical and inexpensive approach? This is where “Boca” comes in. Boca is a 3D printed open source platform for manufacturers and researchers interested in exploring control theory and Machine Learning. Boca has eight degrees of freedom, thanks to the 8 servo motors, with some great…
In this project an Arduino Uno was used to build a robot fridge that follows our movements. This uses Bluetooth and GPS communication to understand the path to follow. In particular, it compares its GPS position with that of the phone of the person to be tracked through Bluetooth communication. Arduino communicates with a GPS…
Home security systems are a growing field of projects. A self-built system is not only generally less expensive than a professional installation, it also allows total control and customization to suit your needs. With the introduction of Microsoft Project Oxford, facial recognition applications are now more accessible than ever to makers. This project uses a…
In this project, we will see how to turn any decorative object into an IOT smart device. Specifically, a plant pot was chosen and it was transformed into a device that sends movement notifications. The heart of the project is an ESP-01 WiFi module for wireless communication and a PIR sensor to detect movement. An…
Who likes a weak WiFi signal? We can extend or improve our WiFi signal in the office or at home using specific products, but these need to be placed in precise points for optimal performance. You can use the device shown in this article to measure the strength of your WiFi signal at various points…
This project aims to monitor the temperature and humidity in a room, through a compact and cheap device, powered via USB and which sends data to our smartphone through WiFi communication. The circuit consists of an ESP8266 module, a DHT22 temperature and humidity sensor and a 3.3V voltage regulator. The ESP8266 module will connect to…
