This is an ECG device made with ESP32, it also serves as a satellite clock and an accurate thermometer!
Introduction
With the development of the Internet of Things (IoT), more and more devices need to connect to IoT platforms for monitoring and management. However, different devices may use different communication protocols and interfaces, which poses certain challenges for integration and management. To address this issue, ThingsBoard has developed open-source software called ThingsBoard Gateway, which acts as an IoT gateway to integrate devices connected to traditional and third-party systems with the ThingsBoard IoT platform.
Role of IoT Gateway
The IoT gateway serves as

Glowing Tube Clock
Over 60 years have passed, and although glowing tubes have been discontinued, many engineers still have a deep affection for them. I created a glowing tube clock using 8 LCD screens to feel the beauty of retro elements and express my respect for past classics.
Project Origin
Recently, I wanted to play with audio playback again.
I dug out some previous articles to review.
This time I plan to use M5stickC, the one with a strap that you can wear on your wrist, yes, it looks great.
I had seen this library before, tested it, and then completely forgot about it. Recently, I was struggling with how to play music using Arduino, tested several solutions

Do you know what Arduino is? Do you know what Arduino can do? Today, let’s get to know Arduino!
Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform.
It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team in the winter of 2005. Its members include Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti.
This article shares a case of lighting up an LED using Arduino.
