Can the single chip microcomputer accept the signal transmitted by the mobile phone or add anything? If anyone knows, please tell me. Or the mobile phone sends instructions to the single chip microcomputer. Yes, but you must buy a GSM module. Single chip microcomputer can control GSM module to dial and send short messages. What I have done is I can only dial, I can't answer the phone and I can send text messages. Enter the telephone number on the development board of the single chip microcomputer and press the dial key to receive the call there. There are many Taobao websites, many of which provide codes. You can buy one, around 200 yuan. I suggest you buy one!
