I want to switch the power supply of some equipment, the PCB board is drawn, and the load is at the positive pole. (Originally, the thyristor was used to shut down the ground).Lithium battery: input v...
I just booked a house, which will be delivered in 2017, which is still two years away. I would like to install some smart home devices in it, but I am confused about how to arrange the control lines. ...
This Misumi MO-R803 camera from Taiwan is known as the world's smallest camera. The lens diameter is 4.4 mm and the length is 15 mm. There is a bendable snake-shaped handle at the back for easy handli...
Process defects in printed circuit design 1. Overlap of pads 1. Overlap of pads (except surface mount pads) means overlap of holes. In the drilling process, multiple drillings in one place may cause t...
As the title says, a sine wave can be output by delay, but the waveform cannot be output by interrupt mode. When simulated by proteus, the following program can output a sine wave, but the frequency i...
First: Click the "L" shortcut key to enter View Configurations. Make sure this option is checked. Second: If the drop-down list in PCB is in the *From-To Editor* state,...

1. Principle of displacement angle sensor
The angle sensor is used to detect angles. It has a hole in its body that fits the LEGO axle. When connected to the RCX, the angle sensor counts once ...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
1 Introduction
Intelligent control instruments are one of the most commonly used controllers in industrial control. They are mainly aimed at a specific parameter (such as pressure, tempera...[Details]
Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[Details]
Corelink Semiconductor has launched the CL1100-based 5-7W E27 LED lighting driver system solution DB2. This driver module meets the requirements of small size (L×W×H=5.1cm×2.1cm×1.8cm), low standby...[Details]
With the widespread application of new services and technologies in the communications industry, the scale and capacity of operators' network construction are getting larger and larger, and the ris...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
