Description:

• This is a Chinese knot electronic kit composed of 81 LEDs, which is driven and lit by the MCU program as required. The MCU has its own oscillation and reset, and the circuit has multiple light control modes.

• After starting up, it plays circularly. Pressing the button can change the flashing speed circularly. Each time you press the button, it speeds up by one gear, and when you press the button at the fastest speed, it will return to the slowest gear. In this cycle, C1 is a standby filter capacitor, which is generally not required to be installed, Does not affect the effectiveness of use.
