#159316 - Limitation of base current to 2N2222? Responding to: ???'s previous message |
So your photo darlington will (without any resistor to limit the current) feed the base of the 2N2222 that is connected with the emitter directly to ground?
Do you really think that the 2N2222 needs so much current on the base? And don't you think that you can skip this transistor and use the uC directly? |
