Meet Easy Pulse: A kit that includes all it needs to make a DIY heart rate sensor. Although it is not built using an Arduino, it is still open and easy to build. From the site: “This project is based on the principle of photoplethysmography (PPG) which is a non-invasive method of measuring the variation […]

Hi guys welcome to this tutorial. One of the most important thing everyone wants to keep track of daily is, time and with easy to use platforms like the arduino it is very easy to create your own timepiece and in the case of this tutorial add a temperature monitor to it. For this tutorial,

This is a fun and pretty easy project that I built as a Christmas present for my kid who loves throwing things. Watch the video to see what it can do. It’s built out of a regular Arduino UNO, pressure sensors made from velostat, and RGB LED strip, and 7 segment LED display. Source code

Infrared (IR) sensors are normally used to measure distances, but they can also be used to detect objects. By connecting a couple of IR sensors to an Arduino, you can make an intruder alarm. Overview Infrared (IR) sensors are normally used to estimate the distance of an object, but you can also use them to detect the

The news here isn’t so much that [Guarav Singh] built this high-quality industrial digital camera from scratch, but it’s in the way it was accomplished. That plus the amount of information that’s packed into the write-up, of course. And the excellent photography. Modularity was one of [Guarav]’s design goals, with the intention of being able to
SCRATCH-BUILT INDUSTRIAL CAMERA’S MODULAR DESIGN REALLY STACKS UP Continue Reading
The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. The three common-cathode RGB photodiodes

The Bosch BNO055 combines tri-axis accelerometers, gyroscopes, and magnetometers to provide orientation to users. About the Sensor The BNO055 uses three triple-axis sensors to simultaneously measure tangential acceleration (via an accelerometer), rotational acceleration (via a gyroscope), and the strength of the local magnetic field (via a magnetometer). Data can then be either sent to an external

The power saving mode here is what sets this Instructable apart from other examples showing day of the week, month, day of the month, time, humidity, and temperature. It is this capability that allows this project to be run from a battery, without the requirement for a “wall wart”. I had posted an earlier Instructable,

Have you shopped for an appliance lately? They’re all LEDs, LEDs everywhere. You might say that manufacturers are out of touch with the utility of tactile controls. [Wingletang]’s fancy new washing machine is cut from this modern cloth. While it does have a nice big knob for selecting cycles, the only indication of your selection

These 7 steps will drive you through the “construction” of a thermo-hygrometer with clock on Arduino UNO. Data and time, humidity and temperature will be shown on a LCD 16×2 display .If you have purchased a LCD display and want to know how to properly solder a pin header to it, take a look at
