Learn how to build a Bluetooth-controlled fire truck using the Arduino UNO R4 Minima board, an HC-05 module, and a water pump. This step-by-step guide covers components, assembly, programming, and testing.
Espressif has announced the ESP32-E22, its first Wi-Fi 6E SoC designed as a radio co-processor for high-performance connected devices, featuring tri-band Wi-Fi 6E, Bluetooth dual-mode, and a dual-core RISC-V processor.
If you are a lover of Retrogaming and do not have the possibility to use the original controllers with the cable, this project is for you. Specifically, an adapter has been built that allows you to use a PlayStation 3 controller on the Nintendo Gamecube in a completely wireless way. The adapter consists of an…
Who has never left their phone in one place and realized too late that they have lost it? In this project we will look for a solution to the problem; whenever you are too far away from your phone, “Don’t Lose Me” will blink and whistle, as well as your phone will play an annoying…
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…
In this project we will see how to build a pair of glasses in which the circuits for Bluetooth headsets are inserted in the frame. Therefore you can listen to music wirelessly while wearing. The circuit consists of three main parts: audio amplifier circuit, bluetooth module and charging module. The TP4056 acts as a charging…
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…
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…
