Power supply is a must for every electronic design competition. As the power supply used in control competitions, because high-power components such as motors are used, it is recommended to use separa...
Network cameras are a new high-tech product. As they span the two previously unrelated industries of network and security, people who work in the network don't know much about monitoring, and people w...
The ACM32F070 development board and the touch function evaluation board can better realize human-computer interaction. The segment code LCD screen on the function board can display 2 lines of 4-bit da...
This is a scanning gun. Can anyone explain how the coil generates a magnetic field after being energized, and the magnetic field drives the magnet on the pendulum mirror to swing? How can an alternati...
DS18B20 pulls up a 5.1K resistor, uses LPC2200's GPIO port to control DQ first, and uses 3.3V power supply (non-parasitic mode). AXD debugging, I counted the probability of possible errors, about 1%. ...
For a linear displacement measuring instrument, when the measured displacement changes from 4.5mm to 5.0mm, the output voltage of the displacement measuring instrument decreases from 3.5V to 2.5V. Cal...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
