硬件在调试过程中，大部分的硬件工作原理都是在单片机开发板上完成的。由于

During the debugging process of the hardware, most of the hardware working principles are completed on the microcontroller development board. Since most of the commonly used modules of single chip microcomputer are integrated on the development board, the module can be connected to the single chip system to be called by connecting or plugging out the corresponding short-circuit cap. <br>The preliminary software program only realizes the control of the timing module of the single-chip system, and realizes the display of the LCD1602 clock. With the gradual improvement of the program function, the key input function and the dosage adjustment function are gradually added, and the time timing and dosage records are added after completion Function, and then add the time display reminder function, and finally complete the buzzer sound alarm reminder function. <br>The verification process of the system hardware can be divided into the following stages with the improvement of the system software: <br>1. Connect the LCD1602 module to the smallest single-chip system, burn the program, verify the display function of the LCD1602, and as the software is modified and improved, the LCD1602 finally displays normally . <br>2. Connect the keyboard to the system, as the software continues to improve. 8 keys are gradually activated. <br>3. Connect the voice LED to the system and replace the buzzer to verify the timing and alarm functions. <br>4. Connect SIM800 to the system and add the corresponding driver to the system to verify the sound alarm function of the system.

Hardware in the debugging process, most of the hardware working principle is done on the microcontroller board. Because the development board integrates most of the commonly used modules of the microcontroller, when enabled, the module can be called into the microcontroller system by simply connecting or plugging in the corresponding short-circuit cap.<br>The preliminary software program only realizes the control of the single-chip system on the timing module, realizes the display of LCD1602 clock, gradually improves the function of the program, gradually adds the key input function and the dispensing function of the drug dose, adds the function of time timing and dosage recording after completion, then adds the timed display reminder function, and finally completes the alarm alarm function of the buzzer.<br>The verification process of system hardware can be divided into the following stages with the improvement of system software:<br>1, connect LCD1602 module to the smallest microcontroller system, burning program, verify the display function of LCD1602, and with the modification of the software, LCD1602 finally normal display.<br>2, connect the keyboard to the system, with the continuous improvement of the software. Step through the 8 keys.<br>3, connect the voice light-emitting diode to the system, and instead of the buzzer to verify the timing and alarm function.<br>4, connect SIM800 to the system, and add the corresponding drivers in the system to verify the system's sound alarm function.

In the process of hardware debugging, most of the working principle of hardware is completed on the development board of single chip microcomputer. Because most of the commonly used modules of single chip microcomputer are integrated in the development board, the module can be connected to the single chip microcomputer system for calling only by connecting wires or inserting and unplugging the corresponding short-circuit cap.<br>The preliminary software program only realizes the control of the single chip microcomputer system to the timing module and the display of the LCD1602 clock. With the gradual improvement of the program function, it gradually adds the key input function and the setting function of the dosage. After the completion, it adds the function of time timing and dosage recording, then adds the function of timing display and reminder, and finally completes the sound alarm and reminder function of the buzzer.<br>The verification process of system hardware can be divided into the following stages with the improvement of system software:<br>1.
