Модуль вентилятора на драйвере L9110

Простой модуль с дайвером L9110, который в свою очередь манипулирует моторчиком-вентилятором. Вы без труда на множестве примеров сможете управлять вентилятором, как обычным потребителем.

Характеристики:

• Напряжение питания двигателей 5V.
• Потребление тока: до 800 мА .

/*********************************************************
* Fan Driver using L9110 Motor Driver
*
* The L9110 Motor Diver is a simple driver designed for
* toys and robots. It has two inputs INA and INB
* and two outputs to drive a simple DC Motor.
*
* The direction of motor spin can be changed and the speed
* can be controlled using PWM
*
* The device described here is the Keyes Fan Board with
* 4 connections
*
* Connections:
*
* INA to Arduino PIN 5
* INB to Arduino PIN 6
* Vcc to Arduino 5 volts
* GND to Arduino GND
*
* Push Button:
* (the output went LOW on pressing on my unit)
* Gnd to Arduino Gnd
* Vcc to Arduino 5 volts
* S to Adduino PIN 7
*
