L293D Motor Driver IC HCSR501 our HC-SR04 sensors undergo qualityL293D Motor Driver IC L293D IC generally comes as a standard 16 pin DIP (dual in line package). This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins (if you do not use enable pins). Each chip contains two full H bridges (four half H bridges). That means you can drive four solenoids, two DC motors bi directionally, or one stepper motor. A motor driver is basically a
