The schemer bus allows you to connect all your schemer-compatible components using only two wires.
This greatly simplifies your project and keeps everything small and neat.

Every schemer-compatible component has a tiny microcontroller under it. Each one has a unique address and is able to send and receive data using the same pair of wires.

It's designed to be very easy to hookup, but it's picky about what it's connected to.

If it's not an Aniomagic product, you probably can't use it with schemer.

Lightboards come in sets of five, and each one has dots to help you identify it. The dots also indicate the PLUS connection to schemer. You can mix them in any color combination (diamond, ruby, sapphire, and emerald). Schemer can directly power up to 20 lightboards, so if you need more, check out Max below.

So how do you tell which color you have? Flip it over.
You can also connect it directly to a 3V battery, and it will light up.

Never use more than 3 volts.

Sensors come in pairs: circle and square. You can use both, only one, or none.
They can both be the same type, or a mix of other types, as long as one is a circle and the other is a square.

• If you don't connect a sensor, schemer will use its internal ambient light sensor.
• If you have only one, schemer will use it.
• If you have both, schemer will use the formula: circle - square.
  This allows you to make (for example) a robot that follows a light or sound.

There is a growing number of sensors you can use with schemer.
Some are entirely self contained, like the light and temperature sensors.
Others - like the touch and custom sensors, allow you to connect your own sensors and conductive fabrics.

Switch is a special component. You can use more than one, but they all do the same thing: when you press it, schemer performs switch procedures. It's represented by the "switch pane" graphical mode. In text mode, you can write things like (if switch) or (if pressed).

It also has two connections that you can hook up to other things like tilt sensors, fabric switches, etc.
It's the sort of thing you'd use to make your robot back up when it hits a wall.

Use Max when you need to connect a lot of lightboards or motorboards.

Connect IN to schemer, and OUT to your other components. Typically, you would use it with a different battery (up to 6 volts), for maximum bling.
