Lesson 7: Variables

At the beginning of this code, what we are going to do at the beginning is to create a variable called ‘a’, which contains the amount ‘500’, and we achieve this with the parameter ‘=‘, within the ‘set’. Later we have added a timer that every second adds 10 to the variable ‘a’ and makes a simple sound.

JSON code:

{	"do": [		{			"set": [				"a",				"=",				500			]		},		{			"timer": {				"do": [					{						"set": [							"a",							"+=",							10						]					},					{						"sound": {							"frequency": "a",							"volume": 2						}					}				],				"every": 1,				"id": 0,				"play": 1			}		}	]}
