Component Introduction
A DC motor is a kind of transducer that converts direct current
electrical power into mechanical power.
To complete this lesson, an extra power supply breakout board is
needed to source much more current to driver the DC motor than
Arduino board can do. The board has a jumper to select 3.3V or 5V
for each output. In this lesson, we only set the jumpers to 5V position
as the picture shown.
L9110 is a driver IC which is used to control and drive motor with two TTL/CMOS input
terminals from Arduino GPIOs.
