DIY Electronic & Soldering Practice Kit - LED Flowing Light Assembly with Microcontroller

This DIY electronic circuit board features a black PCB construction intended for hobbyists looking to practice soldering and learn dynamic LED control systems. When connected to a power source, the board activates an 81 LED array that displays continuous flashing sequences. 1. Assembled manually by the user, the board requires careful attention to component polarity during the installation of diodes and integrated circuits. 2. Eighty-one LEDs are arranged in a thumb-like shape and driven by a DX158 microcontroller using factory-loaded programming to generate synchronized light effects. 3. Functionality is controlled through an S1 power switch and an S2 adjustment button that modifies the animation speed, powered by a 4 to 5 volt DC supply through a small DC socket. 4. The shipment contains one unassembled PCB kit and one power cable, with all required electronic components supplied while excluding the 5V charging adapter.
