Usually...

You can make robots,

It's good for you and your family

This is mostly about

LEGO and Arduino

Let me tell you a story...

"...But, how do I make it move?"

"...But, how to I

get rid of the wires?"

A detour through

hobby electronics...

Arduino

• Small and cheap

• Inputs and outputs

Diode

• Directional

• Forces current
  1-way

LED

• Directional

• Lights up

• Use a resister!

Resistor

• Non-directional

• Limits flow of current

Transistor

• Directional

• Switches currents, large or small

Programming an Arduino

Firmata!

composer require carica/firmata

I you're using a Mac

(and a wired connection to the Arduino)

brew install php@5.6
git clone https://github.com/oasynnoum/phpmake_serialport.git
phpize
./configure --enable-Gorilla
make
make install

brew install php@5.6
git clone https://github.com/oasynnoum/phpmake_serialport.git
phpize
./configure --enable-Gorilla
