L293D is a monolithic integrated, high voltage, high current, 4-channel driver?you can use DC motors and power supplies of up to 36 Volts, the L293D chip is also known as a type of H-Bridge?which is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.
Uno R3 ATMEGA328 CH340 Development Board
Arduino Uno R3 is a microcontroller board based on the ATmega328P. It features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. Due to the low-cost, you can tinker with your UNO without worrying too much about doing something wrong.
