Bluffers Guide To NodeBots

NodeBots are robots powered by JS

NodeCopters are flight capable NodeBots

Most NodeBots are johnny-five

johnny-five is JS for Arduino

Arduino is a programmable usb device and IDE app

IDE uploads programs for blinking LED's to the Ardunio

IDE is love-child of Processing (Java) & Wiring (C++)

johnny-five is Ardunio IDE avoidance tool

Firmata is an Ardunio sketch and generic comms protocol

Firmata exposes Arduino pins to the serialport

Ardunio <-> Firmata <-> Serialport <-> johnny-five <-> You

Important safety notice

HARDWARE IS HARD

Testing is hard

Reality has a terrible API

  • The generous motor
  • The enfebled servo
  • Fudge's Constant
    • Analog noise (inputs are wobbly)
    • Digital noise (put a pull-up resistor inline with a switch)
