There are many smart devices available to us that are able to detect our heart rate and other bio data by using a method called photoplethysmography (PPG), a concept of how blood is able to reflect red light while absorbing green light. The device can detect the amount of blood flowing, so when there’s more […]
Chore Tracker is a device used to help motivate you to do your chores, and manage your time. Each week, Chore Tracker gives you a goal to complete five chores of your choice. It will set a timer for you to stay on track and complete your chore as well as track your progress throughout […]
Arduinos are incredibly useful tools for all sorts of projects. Given the current COVID-19 pandemic, having easy, fast, cheap, and reliable access to health information is more important than ever. While an Arduino might not be the tool of choice for proper medical applications, we can draw inspiration from medical devices to create fun and […]
Hello to everyone, today I am here to show you a very insteresting project that I was working on for a while, it consists on a digital scale using the ESP-12S microcontroller plus a load cell and it HX711 wheatstone bridge to i2c converter, it is capable to measure weight precisely in the spectrum of […]
Today is Friday, January 29, 2021, control of the COVID-19 in Beijing is also promoting the “New Year in place”, family said the Spring Festival can not visit each other, or each person is fined 1500. It seems to go out as little as possible, if there is nothing to do you’d better to stay […]
This is a little diorama made with Arduino for a school project. What happens is a party which just stops playing music. As the sound stops there’s a bright light which turns on. There are two partypeople. One is having a stroke or something because of the alcohol. The other one thinks ‘Dam’n, the party […]
Hello, I’m Andre and this is how you can build and design your own robot with dancing features. This robot was designed as a team project for my junior design class at Georgia Tech. The entire system is completely controlled by an Arduino Uno microcontroller, with various user interface devices. The fundamental components to the […]
Add a remote buzzer to Smoke Alarms that are too far away be heard. Also add an optional Microcontroller interface e.g. Arduino. This document describes how to: Modify an escape-light type smoke alarm to sound a remote buzzer Create the buzzer module Create a microcontroller alarm interface including PCB layout Use an Arduino code example […]
Air Quality Prediction is a project that balances Arduino development and Machine Learning. I have always found the world of machine learning captivating but was never able to run models on real-time data. Arduinos provide the solution with a vast array of sensors supported on their microcontrollers. As a result, I knew that I wanted […]
I had 8 small and really old servos, as well as an ESP32 that was soldered onto a copper stripboard. I therefore decided to make a walking quadruped that would have something sticky on it’s stomach, allowing it to pick things up secretly when it belly flopped, (Like a card). Because I only had 8 […]
