DFRobot project collection

Reading time: 2 min. The DFRobot company has recently showcased a couple of interesting projects using Arduino and Raspberry Pi, along with a selection of sensors and modules produced by the company.

Windloom

Windloom is an interactive installation, based on a digital efficiency project by NIME (New Interface for Musical Expression). It was actually inspired by the author’s memories of his grandmother, turning into a futuristic reconstruction of her air bellow and loom. The device makes use of physical processing technology, along with Max Msp and various gestures of pulling on the air bellow’s wind box, touching the loom’s threads, as well as music composed with the help of Lu Wang.

Among other components, the device makes use of a proximity sensor, a pressure sensor, a button, Arduino Mega, 3 LED strips, and two motors.

Real Life Color Picker

This one is also made using the Arduino interface. The device can easily recognize the color taken from a given object in real-time, outputting its hexadecimal or RGB code on the display.

In creating the project, the author used a TCS34725 color sensor, an LCD 2×16 I2C display, DFRduino Pro Mini, two CR2032 battery holders, a slide switch, an RGB LED module, various cables, a 3 x 7 cm breadboard, and male and female connectors.

Clever Rabbit Hat

This little project makes use of an EMG sensor to mimic muscle and nerve tissue activity in humans. Connected with a funky rabbit hat and a few additional components, the project turns into a humorous hat that can detect your facial expressions, including anger, grimace, shock, and so on. When a dry electrode is placed in the sensor area, the device is able to determine the expression based on muscle activity.

Weather station with data storage

This project delivers a fully working weather station with integrated data storage capabilities. The project makes use of two individual modules – a solar energy controller and a simple SD card reader, in addition to the weather station components.

The project makes use of a weather station module, SD module for Arduino, an SD card, solar energy controller module, a 5V 1A solar panel, nylon cable bands, an assembly kit, an LCD display, a breadboard, a Li-Ion battery, a waterproof case, conduits, resistors (2x 10kOhm), Arduino, and Raspberry Pi.
