51 microcontroller to make alarm clock

Overview

Use 51 microcontroller to customize the alarm clock, and you can freely set the alarm clock and alarm time. Use the Android cable to connect the voice chip and connect it to the computer. At this time, there is an extra removable disk on the computer, and then put the sound file into the removable disk.

Materials used:

Voice playback module

Yabo 51 microcontroller (refer to the digital tube and the 8 free IO ports of this microcontroller)

3 10k resistors

…………

Put the sound file into the voice chip and connect the data cable and power cable to the microcontroller.

Use the keil tool to generate a hex file from the C program and write it to the microcontroller...
