I don't know what to do recently, I bought a Battleship STM32 development board from Zhengdian Atom on impulse. I have been working on hardware before, but it is still very low-end products. My softwa
Experimental principle: This example is a demonstration program for using SIM800 to send and receive data via GPRS. Experimental phenomenon: After the program is run, set the DMZ of the router, open t
[color=black]LED is originally a diode. Of course, a diode can be directly connected to AC power. A rectifier diode can be directly connected to AC power. However, the voltage resistance of a general
