Source: InternetPublisher:同住地球村 Keywords: BSP light emitting diode Updated: 2021/03/11
When the light is sufficient, the light-emitting diode
VL goes out; when the light is insufficient, the VL flashes.
Changing the values of Ri and C can change the oscillation frequency. By adjusting the resistance of resistor Rz
, the sensitivity of the device can be adjusted.
