motor-l298n v0.0.1

motor-l298n

Control an l298n motor from the Raspberry Pi.

Install

The package can be installed using npm.

$ npm install motor-l298n

Usage

The class controls two motors connected to an L298N. The motors are known as LEFT and RIGHT.

We create an instance of an l298n with:

module.setup(in1Pin, in2Pin, enable1Pin, in3Pin, in4Pin, enable2Pin);

It has a number of core capabilities that are motor related. First we have the notion of the rotation speed. This is measured in a percentage of maximum speed:

l298n.setSpeed(side, 60);

Setting the speed doesn't actually cause the motor to turn. We would then call one of the direction functions which are:

l298n.forward(side);

and

l298n.backward(side);

Calling either of these starts the motor turning at the currently set speed. If we change the speed while the motor is rotating, it will change the rate of rotation.

If we wish to stop a motor from turning, we can call:

l298n.stop(side);

In summary, the methods are:

Dependencies

This package depends upon:

• Wiring-Pi - Node.js binding to wiringPi
