Design of solar energy swing circuit board

  Design of solar energy swing circuit board: it includes solar cell B and control circuit. The solar cell B is connected with the control circuit. The control circuit is composed of multivibrator circuit, capacitors C3 and C4, resistance R5, triode Q3 and inductance L The utility model consists of a multivibrator, and then drives the electromagnetic coil through one-stage amplification. The designed working current is very small. Compared with the module circuit, the requirement for the power of the solar cell is greatly reduced, so that the swing ornaments can be driven normally
