Good day, all
Recently, I am doing a project that use arduino uno to switch on and off a photoelectric sensor (according to Infrared Photoelectric Switch). How do i test the current of the output signal black wire as i worry that the arduino can only take in 5V and 40mA. I have connected the brown to 18V power supply, blue to collector of transistor and 5V supply to the base transistor.
Parts Used:
NPN photoelectric sensor
supply voltage 10-30V
output current <100mA
power consumption <20mA
NPN Transistor 2n3904
