This ECG (electrocardiogram) unit has an integrated 2.8 “display. The latter can show individual heartbeats in two different formats and a Poincaré texture. It is battery powered and can be worn around the neck on a lanyard....

  The idea of this project has been on my mind for a while. The question of what if we can use our environment as a technology canvas motivates me to start experiment with this project. Luckily...

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 aim of the project is to measure the energy consumption of the hoverboard during different driving situations. For this reason, Niklas Roy decided to develop a power meter similar to the car’s on-board computer. Roy’s handheld...

  Testing the sensor is the very first step when we start to build a new Arduino interactive project using sensors. If you are a fans of open source hardware, you may have dozens of sensors in...

  I wanted to make a quirky project using some 8×8 matrix LEDs and some ultrasonic sensors… something different from what other people usually make with ultrasonics – and I wanted it to be fun and playful....

From computer interfaces to textiles, musical instruments to interactive artworks, we experience the world by touching it. Getting touch right in the design of objects and products is essential – this is where the Trill sensors come...

  A small jewel capable of detecting atmospheric pressure and temperature, designed for the construction of weather stations or applications where it is important to know these parameters, such as air mass meters and altimeters. Let’s try...

The ST LPS35HW is a water resistant barometric pressure and temperature sensor that is also safe to use in wet environments. In fact it combines protection from water intrusion with support for high precision relative and absolute...

  Let’s test the D7S by Omron, the world’s smallest seismic transducer, and create a seismograph capable of a sensitivity and an accuracy that are comparable to the ones found in professional tools.   Each day, thousands...

  A solid-state amperometric sensor, capable of measuring up to 5 A providing a voltage that is directly proportional to the current. There are many practical situations where we need to know the current absorption of a...

  Let’s discover a set of low-cost gas and pollution detectors that may be easily accessed from the Arduino World. Detecting and measuring pollution and the main gases (the ones we may come across in our daily...

The Gumstix RoomSense is a USB dongle board that can detect room occupancy using passive infrared (PIR) technology and report on temperature, humidity, and barometric conditions. The board can be customized in the Gumstix Geppetto online development...

  Based on Time of Flight technology, the module provides information to a microcontroller regarding distance detected in front of its optical sensor based on time-of-flight of a light impulse.   Contactless distance measurement, therefore employing electronics...

With Very Useful Circuits, foundational concepts of electrical engineering are explored through progressive projects that illustrate the concepts in action. Instead of abstract words and dry formulas, explore the function of transistors, capacitors and resistors by building...

Microsoft has released an early version of a free, open-source Raspberry Pi simulator that can be accessed right through a web browser. Using Microsoft’s Azure cloud computing platform the simulator allows users to code an emulated Raspberry Pi using...

  A virtual shield and a smartphone, with the addition of ultrasound sensors that allow us to detect passage and direction of anyone crossing a passage. Most of Arduino’s success is also due to the fact that...
