I apologize if you find spelling errors or nonsensical text, my language is Spanish and has not been easy to translate, I will improve my English to continue composing instructables. In today’s technology, especially electronics have come a long way, to the point that today can make projects a few years ago were very complicated […]

This tutorial will explain how to build a machine for biofeedback. But first a bit of theory. What is biofeedback? [Font: Wikipedia | https://en.wikipedia.org/wiki/Biofeedback] Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to

Adafruit has announced the availability of the LPS33HW Water Resistant Pressure Sensor offering 24bit pressure data and 16 bit temperature data, allowing it to provide users with pressure readings with +/- 0.1% hPa accuracy. The small sensor can measure from 260 to 1260 hPa and is able to withstand pressure up to 20 times its
Water Resistant Pressure Sensor LPS33HW now available from Adafruit Continue Reading
Angle sensing has always been challenging particularly in industrial and automotive environment because of the need for precise and accurate sensing at high speeds. Allegro Microsystems developed the A1330 an integrated circuit angle sensor that works based on magnetic Circular Vertical Hall (CVH) technology. Unlike other angle sensors Allegro’s A1330 does not require a concentrator

Theory of operation In series thermocouple soldering iron have a thermocouple in series with their heating element and thus only have two connections (actually one more which is electrically connected to the tip for ESD purposes). When a voltage is applied to the two terminals the tip heats, when unpowered the thermocouple voltage can be

Sometimes a clever hack of an off-the-shelf product can come courtesy of its dismantling and hardware modification, but at other times the most elegant of hacks can be made without ever turning a screwdriver. [Brian Lough] was given the request by a friend to replicate a commercial child’s night light that changed colour with temperature,

Hi guys welcome to this tutorial. Today we will be building a simple temperature monitor using the DS18B20 sensor with a Nokia 5110 LCD Display and an Arduino mega. Introduction The DS18B20 digital temperature sensor gives a 9-bit to 12-bit Celsius temperature readings and also has an alarm function with nonvolatile user-programmable upper and lower

Lithium-ion batteries are very popular as they’re lightweight and have high energy density. But at the same time, li-ion batteries are very sensitive to overcharge/over discharge. An internal short circuit can cause fire and it may even lead to a violent explosion. Fortunately, nanotechnology found a way to prevent this kind of nightmare. How? let’s

In this project I’m going to create a simple Datalogger with my Arduino and an Ethernet shield. I’ll be using a photoresistor and a temperature sensor and all the information will be stored in a micro SD card.The idea is that you can apply this to any sensor you desire! Watch the Video below: Step

We already know, that Switches MEC Unimec switch in up to eight ways and also that they´re available as momentary or alternate (latching). UNIMEC switches feature perhaps only one “disadvantage” – that on the same PCB no other higher components can be used (which would be higher than the switch). If you´re satisfied with the UNIMEC features, but despite
