Bluetooth, an ancient and excellent technology, has brought many stories with the launch of Apple's AirPods. As a practicing engineer, I would like to share with you some of the stories about it, main...
I would like to ask, what should I pay attention to when installing the GSM module? I want to use the hyperterminal to debug it first, but I don’t dare to power it on for fear of burning it. What shou...
The T1 16-bit timer of M16 has a total of 15 working modes, and the other two 8-bit timers (T0/T2) are relatively simple, except that T2 has an asynchronous working mode for RTC applications (overflow...
The current key tone is what was used when the kernel was generated. I want to change it to a different sound. How can I change it? Where is this sound file hidden? Has anyone changed this key tone fi...

The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
As a simple and practical input device, buttons have been used in various microcontroller application systems and are ubiquitous. However, the buttons used in different practical occasions are also...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
LonWorks fieldbus technology is widely used, for example, in intelligent buildings, industrial control, environmental protection, etc. Echelon's LonWorks system has been used in the products of tho...[Details]
Stepper motors, also called steppers, use the principles of electromagnetism to convert electrical energy into mechanical energy and have been used since the 1920s. With the increasing popularity o...[Details]
