Technical summary
l293d is an integrated, monolithic high-voltage, high-current, 4-channel driver
Basically, this means that using this chip, you can use DC motors and power supplies of up to 12 volts
The h-bridge is generally an electrical circuit that enables a voltage to be applied across a load in either direction to an output, for example a motor.
That's fairly large motors and the chip can supply a maximum current of 600mA per channel, the l293d chip is also what is known as a type of h-bridge.
Can drive 4 DC motors or 2 stepper motors or 2 servos
