Strand 7.1: Forces are Interactions between Matter
* Standard 7.1.3
>Construct a model using observational evidence to describe the nature of fields existing between objects that exert forces on each other even though the objects are not in contact. Emphasize the cause and effect relationship between properties of objects (such as magnets or electrically-charged objects) and the forces they exert.
* Standard 7.1.4
>Collect and analyze data to determine the factors that affect the strength of electric and magnetic forces. Examples could include electromagnets, electric motors, or generators. Examples of data could include the effect of the number of turns of wire on the strength of an electromagnet, or of increasing the number or strength of magnets on the speed of an electric motor.

The text is put in the ``||basic:show string||`` block (The title is put in the ``||basic:on start||`` event so when the micro:bit is started up it will show what it is programmed to do. It is done in all CAPS because it is easier to read as it is displayed in the LED display).

### on Button “B” Pressed event
1. The code for on button **B** pressed is designed to return a converted value for the battery’s voltage in millivolts (1.5 volt = 1500 millivolts).
2. The beginning of the first statement a variable “voltage” is created and given a value of the reading from the analog reading of pin **0**. The number is then multiplied by 1000 and divided by 340.
3. If 3 volts gives a reading of about 1023 then 1 volt should read around 340. (340 = 1024 / 3). Using this ratio and multiplying the number by 1000 should convert the number to millivolts (micro:bits only do integer math so the voltage is multiplied by 1000 before doing the division by 340).
