I want to use a 51 single-chip microcomputer to control two stepper motors to move in an arc, but I don't know how to calculate the arc, that is, how many steps the Y axis will take if the X-axis moto...
When the WDP500-2A plane grating monochromator is used to test the emission wavelength of a high-power laser diode at different currents, the matching of the laser diode has the disadvantages of lo...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]

For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[Details]
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]
Smart lighting control systems provide high controllability for various buildings and further enhance the level of green energy. They are the core products of energy conservation and digital techn...[Details]
With the continuous consumption of earth's energy and the scarcity of resources, the harm of greenhouse effect to human beings, and the serious pollution of the atmosphere to the earth, the intern...[Details]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]

With the rise and continuous improvement of the solid-state lighting industry, light-emitting diodes (LEDs) have become an alternative lighting technology and are gr...[Details]
The traditional display screen using 51 single-chip microcomputer to control LED dot matrix has relatively simple functions. If it is to achieve diversified functions, it often takes a lot of time ...[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]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
Experimental tasks
A DS18B20 is used to form a temperature measurement system. The temperature measurement accuracy reaches 0.1 degrees. The temperature range is between -20 degrees and +50 de...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
