I've designed the following circuit:
**broken link removed**
note:
IGNORE THE REGULATORS UP THE TOP, JUST TAKE THE VOLTAGES AS THEY ARE IN RED.
heres what it does:
the switches J4 and J3 are representing a PIC microprocessor which determines the direction of a DC motor and spits out logic 1 accordingly. J3 is logic 1 when the motor is turning clockwise, J4 is logic 1 when the motor is turning counter clock wise.
Heres the problem:
Why is it that I only see .5V at the source of Q2 and Q4 when the corresponding switch is closed (this is in reality too, not just in simulation). But when I remove Q1 and Q3 I see the more correct voltage of around
+9.2V.
