Project – two servos and the REPL
Now that we have one servo up and running, we're going to wire up a second one and use the REPL to explore the Johnny-Five Servos object, which is meant to help control several servos at once.
First, let's wire up our second servo.
Â
Wiring up a second servo
Take the second servo, figure out which side is ground, put that one on the bottom, and slide the three-pin socket over the pins in the second column (pin 1):
Now that we've wired up a second servo, let's start coding our Johnny-Five servos object!
Using the Johnny-Five servos object
The Johnny-Five servos object is meant to help you group servos in ways that make sense for projects with many servos, such as hexapods with six legs, each containing multiple servos.
Â
You can create a Servos object in a few different ways; the way we will use is to pass an array of constructed servo objects:
let servos=newfive.Servos([servoOne,servoTwo])
This is where the magic happens—now that our servo objects are grouped in a...
