DC4.5-9V 81 LED Follow Spotlight Adjustable LED Game DIY Welding Electronic Kit

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

CD4060 SMD Music Light Circuit Welding DIY Kit LED Electronics Project Welding

In the circuit, resistors R1, R2, R3 and electrolytic capacitor C4 CD4060 RC oscillation peripheral circuit, change R3 can change the frequency of the oscillation circuit. The circuit selected Q5-06 three outputs, when the pin outputs a low level, and the connection of the transistor conduction, connected to the transistor emitting school LED light.
