I finally got one thing working... for a while, I had the
motors running on battery power and the pic running on the
power from the protoboard, so the signal that I was sending
wasn't going anywhere, but since I had the multimeter
plugged into the potoboard's ground and the signal, it was
telling me that it was going somewhere, so I switched the
pic over to battery power, cause I was getting some strange
reading for the battery power and it worked.
But then I went to build the rest of the H-Bridge, but with
a different twist.
I have the 121's on the same circuit and the 126's on
another, (the 121's are controlling one way and the 126's
are controlling the other, so that I only need to use 1
signal pin for the forwards/backwards controlling). After I
finished the H-Bridge and checked it I went on and applied
power to the entire circuit. The motors were going one way
and didn't go the other for some reason, so while it was
running I went to adjust something and touched the
transistor and then burned my finger. All the transistors
were scorching hot, so I quickly unplugged the power.
Something went wrong, but I have no idea what it could be...
I did a couple of tests and found out that the Pic didn't
seem to be running when everything was being powered, but
when it was alone in a circuit it ran fine (I have an LED on
another Output telling me when the other output is High or
low, so when I had the PIC in the circuit with all the other
devices, it didn't light up at all)...
