Simple H Bridge. The 4 transistors act like 4 switches so by turning on one diagonal or another you can make the motor turn forward or backward. An h bridge is built of four switches that control the flow of current to a load.
Only a handful of parts are needed. The circuit works as follows. Simple h h bridge circuit for motor control the simple h from robot power is a low cost robust h bridge circuit designed for use driving dc motors or other dc loads in the about 25a and 6v 28v range.

H bridge on a breadboard step 1. Only a handful of parts are needed. The simple h from robot power is a low cost robust h bridge circuit designed for use driving dc motors or other dc loads in the about 25a and 6v 28v range. Here is where the h bridge comes to help.
