One of the electric fan natural wind simulator circuits
Source: InternetPublisher:桂花蒸 Keywords: Simulator BSP multivibrator Updated: 2021/09/16
The circuit is shown in Figure 3-8. It can make the fan rotate and stop, and the air volume gradually increases from stopping to gradually decreasing to stopping, and
the cycle repeats. It is controlled by a self-excited multivibrator composed of 555 time base integrated circuit A and so on . Adjusting the potentiometer
RP can change the circuit cycle working time.
