transistor npn

I'm trying to trigger 24volts 1AMP output with a PNP that should be off normally and get turned on with 3.3v output that turns on a NPN. I'm having a hard time trying to figure out resistor placement and value. Any help would be apricated.

Hi Everyone, I have the circuit that controls a dc motor using the L9110s motor driver. It is powered by a 1.5V AAA battery that is stepped up by the TI TPS61027DRCR TO 5V. The goal of this circuit is that when the ITR8307/TR8 Optical IR Sensor sees a white stopping plate, the motor no longer...

My project purpose is that when you hold hands with a friend the passage of electric current through a circuit is enough to turn a buzzer or the ISD1820 voice recorder speaker. My first idea it to use the circuit below as reference, but I have no idea which transistor I should use to have...
