Analog Reads

You can also read analog values like from a

potentiometer or sensor.

Lets do a demonstration where the center tap of a

potentiometer is hooked up to Signal #3 - don't forget to

also connect one side of the potentiometer to 3.3V and

the other side to ground.

And here is the example code. You can see we read the signal with crickit analog read signal which returns a value

from 0 to 1023.

For Crickit and Circuit Playground Express

The map MATH function changes 0 to 1023 to 0 to 9. The graph NEOPIXEL block will light the number of NeoPixels

map returns in rainbow colors.

Be sure the potentiometer is connected to Crickit Signal 3 and not one of the other Signal terminals.

For Crickit and micro:bit

The code displays a heart icon on the micro:bit display. The brightness is changed by taking the reading from the

potentiometer connected to Crickit Signal 3 (0 to 1023) and dividing by 4 to get a brightness from 0 to 255. So the

potentiometer is essentially a manual brightness control for the micro:bit LED array.
