Red, green, and yellow LEDs can work at 2-15V, and blue and white LEDs need 4-15V power supply. The higher the voltage, the faster the flashing and the greater the brightness. The circuit board is processed with 1.5mm high-quality glass fiber board, the pad is super large, the wire is thick, there is no flying line, the component layout is beautiful, and the copper surface is sprayed with tin. Specially optimized design for practical training, it is convenient to withstand repeated desoldering and can improve the efficiency of use. This circuit is especially suitable for beginners, with strong interest, obvious effect and low production difficulty. It is the material of choice for assembly practice and skill training. This circuit is a cyclic drive circuit composed of 3 transistors. Whenever the power is turned on, the three triodes will compete to be turned on first, but due to differences in components, only one triode will be turned on first. It is assumed that V1 is turned on first, then the collector voltage of V1 drops, causing the left end of the capacitor C2 to drop, close to 0V. Because the voltage across the capacitor cannot change suddenly, the base of V2 is also pulled to approximately 0V at this time, V2 is
