✨Function Description:
This is an LED follow spotlight LED game DIY kit. It can move the LED along the X, Y, and XY axes, and the direction of movement can be controlled by buttons. It can also adjust the speed of LED movement and produce various LED flashing effects. 81 high brightness red indicator lights simulate the game tracking effect of LED lights.

✨Parameter:
Supply voltage: DC 4.5-9V (DC power supply)
PCB board size: 71 * 93.5mm

✨Circuit principle:
U1 and its peripheral components form an oscillating circuit, which is sent to CD4017 for counting and decoding through the third pin of NE555. High level driving transistors Q1-Q9 are respectively output from the Q0-Q8 output terminals to achieve the function of lighting up the X-axis LED. Similarly, U3 and U4 drive transistors Q10-Q18 to conduct alternately, achieving the function of lighting up the Y-axis LED. Switch S2 can switch the size of the oscillation capacitor connected to U1, VR1 can adjust the X-axis oscillation frequency, switch S3 can switch the size of the oscillation capacitor connected to U3, and VR2 can adjust the Y-axis oscillation frequency. S4 can switch the Y-axis to X-axis and count once after the cycle ends, achieving the effect of lighting up the line by line flow. S1 is a power switch, and the power can be input from the J1 socket or the BAT auxiliary input port, with a voltage of 4.5-9V DC.
Attention: All light-emitting diodes, electrolytic capacitors, transistors, integrated circuits, and power ports have polarity. Be careful not to install them upside down, and all components must be mounted on a board.

Package Include:
1 * DIY kit
Note: DIY of individual parts requires self welding and assembly to enhance hands-on skills. Self provided welding tools are required for welding.
