How it works:

R1, R2, and C1 are connected to the NE555 integrated circuit, forming a multi harmonic oscillator circuit.
The circuit outputs high and low signals at approximately 1 Hz through pin 3.
When pin 3 outputs a low level, LED1-8 light up; when it outputs a high level, LED11-18 light up.
LEDs 1-16 are arranged in a cross row, using red and green colors alternately.
Once powered on, the circuit creates a flowing, flashing light effect.

Assembly Instructions:

Organize Components: Arrange all parts (LEDs, resistors, capacitor, NE555 IC, Battery Holder) so you can see everything
Install 10K Resistors: Solder the two 10K resistors (brown, black, black, red, brown) onto the PCB in slots R1 and R2.
Install 1K Resistors: Solder the sixteen 1K resistors (brown, black, black, brown, brown) onto the PCB in slots R3 and R18.
Place Red and Green LEDs: Insert the LEDs into the board in alternating color starting with red at the top of the board. Place them all around the edges aligning their polarities (longer leg = positive) so the positive legs are closest to the outer edge of the board. Solder each in its position.
Install 555 Timer IC: Place the NE555 IC on the PCB and solder it securely. Make sure the notch on the circuit board matches the notch on the chip.
Attach Capacitor: Solder the capacitor C1 as indicated. Ensure proper orientation for polarized capacitors where the longer leg is + and - is labeled on the capacitor.
Install Battery Holder: Attach and solder the battery holder on the back of the board. Make sure the notch is in the marked position as printed on the circuit board.
Inspect Connections: Double-check all solder joints for completeness and potential short circuits.
Test the Circuit: Plug the battery into the battery socket on the back and enjoy the LED light show! Congrats!
