Arduino Based Dual Motor Driver

The project aims to develop a control on two 12V DC motors by using a SN754410NE Quad Half H-Bridge IC.

The pin-out of the H-bridge contains a u-shaped notch at one end which can provide help in identifying pin 1. +5V is assigned to pin 1, 9, and 16; +12V is at pin 8 which will run the +12V DC motors. The GND is assigned to pins 4, 5, 12, and 13. There are two hook ups on the DC motors wherein one lead goes to positive and one lead goes to GND when it is hooked up straight to the power source.

The left motor leads will be hooked up to pin 3 & 6 for this H-bridge driver while the right motor leads will attach to pins 11 & 14. The pin 2 of H-bridge connects to the Arduino digital pin 2 and the pin 7 of H-bridge to Arduino digital pin 3. H-bridge pin 10 to Arduino digital pin 8 and H-bridge pin 15 to Arduino digital pin 7.

Up to 36V can be handled by the IC which can be used for building robots that use 12V motorcycle battery.
