- Then the circuit design principle is simple and easy to understand, suitable for novice soldering or school as a starter kit for subject training.
- The swing speed can be adjusted by replacing the components themselves.
- The larger the capacitance value of C1 and C2, or the larger the resistance value of R1 and R2, the slower the swing speed.
- Package parameters: Power supply voltage: DC 3-5V USB Board size: 8.2×7.5cm
- Composed of Q1, Q2 harmonic oscillator, to control two sets of LED lights flashing alternately, 83pcs LED arranged in a swinging bell shape.
