Then I think OP should read the datasheet and use the values to calculate the needed resistors.
Here is my total circuit, essentially what we're doing is comparing A0, A1 and A2 to A7 to get our total current/power output through there, then measuring A3 vs A5 and A4 vs A6 to get the actual current going into the battery. I assume based on what I have learned today that these PNP transistors won't really work for my purposes... but I would love to know if I am right in thinking that.
I attached a modified drawing of the circuit, you were missing a single resistor between 6V and the collector. Also good to know about PNP being LOW to be "on" I've only ever worked with NPN and bought these by accident smiley-red. This resistor issue actually throws a lot of my project into question... much of it involves reading voltages across .3 ohm resistors. I am going to have lunch and then upload another question about PNP switching involving the rest of my circuit. Don't worry I'll draw it this time smiley-wink
The problem with your circuit is, that the Arduino-pin goes up to approximately 5V only. Since your PNP-emitter is connected to 6V, the base gets some current (1V - 0.7V = 0.3V; 0.3V at 1K gives 0.3mA). Since your complete "load-current is about 2mA, a transistor with a B of 150 will turn on to some degree. So you can never turn it off.
I'm afraid I'm a little rusted !
