A comprehensive Arduino library for interfacing with Atlas Scientific conductivity (EC) sensors via I2C communication. This library provides both simple API calls for basic readings and a full command ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

Botanical sensors are turning greenery into living data networks while monitoring plant health and optimizing yields.

Some of the most revealing signals about human health are carried in fluids that are almost impossible to measure. Tears, ...

This experiment revisits a long-running attempt to build a working camera lens and image system from scratch, then upgrades it into a usable camera for a live public event. After previously producing ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Abstract: This paper proposes a low-cost planar microwave sensor able to monitor the wrist pulse wave (WPW) when it is in contact with the anterior part of the wrist, near the radial artery. The ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
