Perché questo preambolo I build circuit which take proximitiy sensor as input to circuit (24V). With this 24V we switch on and off NPN transistor. On the side is Arduino with interrup. On the side is Arduino with interrupt enable when pin is LOW. So I need circuit that convert 24V pulses to 0V and 5V pulse for Arduino input The transistor has three leads. Most of the electricity flows from the Collector to the Emitter, but this will only happen if a small amount is flowing into The pin D3 of the Arduino is connected to the resistor. Just like when using an LED, this limits the current flowing into the transistor through the base The transistor allows you to control a circuit that's carrying higher current and voltage from the microcontroller.

. Use an Arduino to test NPN and PNP BJTs. Here's a quick video of the circuit in action: Notes. A bipolar junction transistor (BJT) can be considered a back-to-back pair of diodes. NPN have the common anode on the base The trouble is, I've forgotten how to do things like calculate the value of a base resistor and the algorithm for loading bits into a shift register. I want to switch on the current through the LED when the Arduino's output pin is high, so I'm going to use an NPN transistor in common-emitter mode
