VDD = 3號電池( 1.5V ) x 3 = 4.5V
LED's VF = 2V
Rlimit = 39ohm
Id = ( VDD - ( VF x 2 ) ) / Rlimit
= ( 4.5V - ( 2V x 2 ) ) / 39ohm
= 0.5V / 39ohm
= 12.8mA
LED : Typical VF = 2V / Id =10mA
SW-200D: Spec.
搖動開關、震動開關 滾珠開關 傾斜開關 雙珠角度感測器
當向導電端(鍍銀Pin腳端 A)傾斜、傾斜角大於15度時間, 為開路OFF狀態,當產品水平狀態發生傾斜改變,觸發端(鍍金引腳C)低於水平傾角大於15度角時,為閉合ON狀態。
電磁式蜂鳴器(外部驅動) LF-MT12D02 Magnetic Transducer : Spec.
線材:
The IR transceiver's commands are unknown.
So this is an unsolved case.
