Step 2Build the H-Bridge Driver
As you are looking at the SN754410NE chip, you will notice a u-shaped notch at one end. This will help to identify pin 1.
Pins 1, 9, and 16 are +5V
Pin 8 is +12V and will run the +12V DC motors.
Pins 4, 5, 12, and 13 are for GND
DC Motors have two hook ups on them. If you hooked one up straight to the source power you would have one lead going to positive and one lead going to GND.
For our H-Bridge driver, you will hook the left motor leads to pin 3 & 6. The right motor leads will hook up to pins 11 & 14.
Connect h-bridge pin 2 to the Arduino digital pin 2, and h-bridge pin 7 to Arduino digital pin 3.
Connect h-bridge pin 10 to Arduino digital pin 8, and h-bridge pin 15 to Arduino digital pin 7
