Heart-shaped running water lamp STC89C52 based on 51 microcontroller

Overview

Design requirements:

1. Use the microcontroller stc89C52 to design a heart-shaped running water lamp.

2** , design circuit diagram, pcb diagram, etc.**

3. The LED adopts colorful fast and slow flashing alternating LEDs.

4. This design mainly includes the 51 microcontroller minimum system (reset circuit + crystal oscillator circuit), power supply part and LED part.

5. There are multiple modes of LED changing effects. The flowing effects have been packaged in the program and can be called separately. 6. A UART serial port programming interface is reserved on the board, which is more convenient for debugging effects.

7. The program starts running when the power is turned on. After the entire process is completed, the initial effect is re-executed.

After the welding is completed, the programming program is tested and the function is normal. Note: The maximum voltage of the DC power input port should not exceed 6V, preferably around 5V, otherwise the microcontroller may be burned.
