Also, a PNP transistor confuses the issue a bit and won't be as simple as this circuit. The problem with a PNP on the 5v side means it will always be on - because the base voltage will be (5- 3.3v) of the wemos and current will flow and the PNP would … WebBOJACK 14 Vaules 840 قطعة 2-125 مم كابلات ... 60V 0.15A 0.4W 8MHZ 25 قطعة--S8050 NPN 40V 1.5A 1W 100MHZ 25 قطعة--S8550 PNP 40V 1.5A 1W 100MHZ 25 قطعة--2N2222 NPN 60V 0.8A 0.5W 250MHZ 25 قطعة--2N2907 PNP 60V 0.6A 0.4W 200MHZ 25 قطعة--2N3904 NPN 60V 0.2A 0.625W ...

WebMar 27, 2024 · 2. Assuming the 2N2222 is good, and the MCU gnd === the emitter voltage, and assuming the MCU output goes to 0.0 volts, that circuit should work. Lets diagnose a bit. Make the base resistor about 1,000 ohms. That puts a (good) transistor well into saturation when MCU output is near 3.3v.
