Light-controlled street light The working principle of the circuit of the device is shown in Figure 12. During the day, when strong light shines on the photoresistor RG, the internal resistance of RG ...
The parameters of the components in the figure are not given, just to see if the principle is feasible. I plan to make an electronic piano, using a single-chip microcomputer to generate SPWM waves to ...
As the title says, what is the difference between adding and not adding? If it must be added, why is it already done inside the microcontroller when it is manufactured?...
I had nothing to do recently. I saw many people playing with quadcopters, and I felt a little itchy. So I spent some money to buy some parts and wanted to build one myself. I bought two ducts and a ne...
