A few months ago I asked about diodes for a basic low voltage H-Bridge. So I got the parts together. The first thing I did was to build a 5V voltage regulator, getting power from a 9V battery. I managed to build the regulator with no issues, it puts out 5mA and about 5V. I went ahead with the H-Bridge, the enable line for the side of the chip I'm using is tied to 5V power through a 1k resister, IC power and the motor power are also 5V but directly connected. The other enable line is tied to ground, as are all ground pins. The motor is connected to the motor pins, the main logic pin is tied to power. I connect the regulator to the circuit.....nothing happens. I break out my multimeter and found that there's no voltage to be found anywhere in either the H-Bridge circuit or the regulator, almost like there's some kind of broken circuit. I used the multimeter to check the connections, never found a broken one. All this makes me wonder if I'm missing something, should I have used a microcontroller or some kind of logic gate instead of connecting the logic directly to power? Or is there something else going on?
