Microcontroller-specific globals. These are the bridge from the code to the game.

Getting parts

Part GetPartFromPort(int port, string partType)

Gets a part from the port number you specify and the part type. One port can be attached to multiple parts, and partType selects which one based on its type (e.g. "Screen").

The port number is a Configurable property on the Port part. This is how you can tell your microcontroller which port you want to use.

Code example

This example gets the Screen connected to port 1, then it clears it.

local myScreen = GetPartFromPort(1, "Screen") -- Gets a Screen from port 1
myScreen:ClearElements() -- Clears the Screen. See the docs for the "Screen" part

array GetPartsFromPort(int port, string partType)

Gets an array of parts from the given port number.

Code example

This example gets all Switches connected to port 1 and toggles each to be active.

local switches = GetPartsFromPort(1, "Switch") -- Gets all parts on port 1 with the type "Switch"
for _, switch in ipairs(switches) do -- Loops over each switch in the list of switches
    switch:Configure( { SwitchValue = true } ) -- Sets all switches' SwitchValue options to be on, so each switch is made active


Port GetPort(int port)

Returns the Port specified by the port number you input. This is the same port number from GetPartsFromPort.

void TriggerPort(int port)

Triggers a Port with the port number you input. This is the same port number from GetPartsFromPort.


void Beep(float pitch)

Beeps with the given pitch. **Beep!**

table JSONDecode(string json)

Takes a json string and decodes it, giving you a complex piece of data.

string JSONEncode(table dataToEncode)

Encodes the data you give as JSON. This can be used to store complex data as a simple string. A ton of modern web services use JSON. JSON can only encode basic data, like numbers, strings, and tables. Anything else will just encode like nil does. That means that you cannot encode Instances, userdatas, functions, threads, etc.
