Arduino - Obstacle Avoiding Robot (with L293D)

Dual H-Bridge Motor Driver for DC or Steppers - 600mA - L293D. This is a very useful chip. It can actually control one motor independently. We will use in its entirety the chip in this tutorial. Pins on the right hand side of the chip are for controlling a one motor. Pins on the left hand side of the chip are for controlling second motor. You can run four solenoids, two DC motors or one bi-polar or uni-polar stepper with up to 600mA per channel using the L293D.”
