ATtiny85 Pulse Oximeter and Photoplethysmograph
Displays your pulse rate, blood oxygen level and a moving graph of each heart beat, the photoplethysmogram (PPG).
Thunder Pack Is a Locally-Powered Arm-Based Board for Wearables
Jeremy Gillick’s Thunder Pack was designed around an STM32 MCU and features an onboard battery, USB, charger, buttons, and status LEDs.
Arduino based Solar Tracker – Stepper Motor & Light Resistor Tutorial
In this project, we will be building a simple solar tracker capable of detecting the most optimal position of the sun on one axis and adjusting itself accordingly. The goal is to create a control loop which will be able to accurately position a solar panel toward the sun.
Make a Non-Contact Infrared Thermometer with IR Temperature Sensor
When debugging an electronics circuit or testing a new hardware design, often times I tend to check if the components on the board are getting hot abnormally by touching them. And if something is messed up (which usually is in the first try) these components could get as hot as 80°C or more burning not only the component but also my finger along with it. After burning my fingers for more times than I could remember I decided to build my own Temperature Gun using Arduino and an Infrared Temperature Sensor. This Thermal gun will be built using a non-contact temperature sensor called MLX90614; hence it can not only be used to measure component temperatures but can also be used for measuring body temperature, surface temperature, Heat ventilation and much more. Of course, these thermal guns are readily available in the market from renowned manufacturers like Fluke, Flir etc. But they are not light on your pockets and on top of that what is more fun than building your own gadgets. So let’s get started…
#COVID19 Realtime Monitor
This little tracker will help you to be up to date about the coronvavirus outbreak and the situation in your country. The display shows alternating the current data of different countries of your choice.
The data is collected by the website www.worldometers.info/coronavirus/
Designing a low-cost, open source ventilator with Arduino #CoVID-19 #coronavirus
Desperate times call for desperate measures, and while making your own medical equipment isn’t normally advisable, Johnny Lee’e project explores how to turn a CPAP machine into a ventilator.
The idea is that since these machines are basically just blowers controlled by a brushless DC motor, an Arduino Nano equipped with an electonic speed controller could allow it to act as a one.
RaspberryPi vs. Arduino : The Battle of the Micros
Hello guys, in today’s articles, I will try as much as i can to do justice to the comparison between an Arduino and a Raspberry Pi. Oftentimes, there has been a comparison between Window Vs Linux, Edilson Vs Tesla, AMD Vs Intel and micro-controller Vs microprocessor. People get confused when it comes to selecting/choosing the right boards for their next project which later leads to an argument or comparison.
Comparing these two boards is like comparing a calculator with a laptop, it’s kinda funny tho. The two boards have their advantages and disadvantages over one another.
How to build a Hidden Shelf Edge Clock – 3D Printable | Elegoo Arduino Nano | Smart Home | LED
I’ll show you how to build a very smart looking shelving system that includes a hidden giant clock in the edges of the shelves, and integrated LED downlighters to show off your favorite items on the shelves.
As the lighting is LED (using WS2821B ‘Neopixels’) you can choose your own colours. A discreet photoresistor also dims the LED’s when the ambient light levels drop – great for evening ambiance in any room.
The Octo-Bouncer
Arduino project with 120 FPS OpenCV image processing and smooth stepper motor moves. The machine calculates the ball’s 3D position from the image processing data and uses this information to control the orange ping pong ball.
