Voltage is powered for indicator lamp.Wherein, supply voltage is preferably 3.3V.Now, when the working condition for detecting electric equipment is to open
During machine state, microcontroller chip controls the conducting of the second output interface output high level signal, now the second triode, the two or three pole
The current collection of pipe extremely low level, therefore the positive pole pin 1 of indicator lamp (corresponding) of the first luminescence unit is low level, now first
Luminescence unit does not work, i.e., red light does not work.And because the positive pole (pin 3 of corresponding indicator lamp) of the second luminescence unit is high level,
The voltage of 3rd triode emitter-base bandgap grading is more than the voltage of base stage, and the 3rd triode ON, therefore, the negative pole of the second luminescence unit are (right
