Kind Reminder: Due to different batches, the power interface of some batches is TYPE-C. If you mind, please buy with caution.

Function Description

This circuit is an innovative design for dynamic electronics. After being powered on, the thumb like pattern composed of 81 LEDs presents various flashing effects. Press button S2 to adjust the water flow speed.

Introduction to Circuit Principles

81 LEDs are connected to a dedicated microcontroller DX158 through a combination of rows and columns, and are scanned and driven to light up in the desired way through the microcontroller program. The microcontroller program in this kit has been burned and welded to produce the desired effect. DC1 is a power socket that is compatible with both a 1.3mm small DC socket and an Android interface power socket. It can be powered by 4-5V DC. The kit provides a small DC socket by default, without an Android socket, and can be powered by any 5V charging head. S1 power switch, C1 is a backup filter capacitor, which generally does not need to be installed and is not provided in the kit, which does not affect the effectiveness of use.

Installation precautions: All light-emitting diodes and microcontrollers have polarity components. Be careful not to install them upside down. If you need other colors or colorful effects, just replace the LED.
