24.11.2020 · You can use any general purpose NPN and PNP transistor like for example 2n2222 or BC547, these are PNP type. You can read in detail about the types of relay and how to use them. In order for the plant to be watered automatically, you need the Python program by the following lines for GPIO control of pin 3: import RPi. GPIO as GPIO. GPIO ... 11 Dec 2018 — Features / technical specifications: · Package Type: TO-92 · Transistor Type: NPN · Max Collector Current(IC): 600mA · Max Collector-Emitter Voltage ... There really isn't a single '2N2222' transistor, since each manufacturer just seems to use XYZ_2N2222 as a part number for a generic 'NPN silicon amplifier transistor'. Hence the 2N2222 pin-out is sadly not standardized. Most 2N2222s have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C ... 2n2222 pin diagram
