Lubricating oil detection based on dielectric principle

This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.

Two-degree-of-freedom pan-tilt robot control platform

This work, titled "Two Degrees of Freedom Pan-Tilt Robot Control Platform", implements a complete pan-tilt robot control platform. The system uses motion sensors as control handles to control the movement of the robot, and cooperates with the OLED screen to display the system's Current status. Using the control handle, you can control the movement of the vertical axis servo through forward and backward movements, and control the movement of the horizontal axis servo through rotation operations, thereby realizing two degrees of freedom control of the robot.

BLDC driver based on GD32

A brushless motor may seem like a simple thing, but it can be very complex to drive. As an electronics enthusiast, I just tried it with the spirit of a newborn calf who is not afraid of tigers. It doesn't take long either. So the things I make only have one look, and I hope you won’t criticize them.

IoT smart lights

Physical network smart lights can synchronize data to users' mobile terminals in real time through the Internet, and users can also remotely control smart lights through mobile terminals. The smart light mainly consists of 3 parts: 1) GD32E231 as the main control, which can control peripherals; 2) ESP8266 as the Wifi communication module, responsible for transparently transmitting data between the main control and the BcServer server, and realizing data interaction with GD32E231 through the serial port; 3) LED lights, that is, peripherals, are controlled by GD32E231 using GPIO. Smart lights and Android APP use Beecom protocol (referred to as BC protocol) to transmit data to each other through the BcServer server.
