3. This kit configures 10 LEDs into a circle, which starts working when the power switch is turned on and the button is pressed, making it easy to use. 2. The pulse generator is composed of NE555 and peripheral components to form a multi harmonic oscillator, with stable performance. 4. Adopting full process processing, large solder pads, thicker wires, and beautiful component layout. 1. The circuit mainly consists of a pulse generator and a decimal counter circuit, with simple operation. 5. This circuit is particularly suitable for beginners to use, with strong interest, obvious effects, and low production difficulty. It is material for assembly practice, skill training, etc., Weight: 0.0661386786 Pounds, Manufacturer: ximie
