What is variable?

Variables

In programming, a variable is a value that can change, depending on conditions or on information passed to the program.

for example, if we want to read the values of light sensors from the CPX,

we need to give it a name so we can call out the values in our code when we need it.

in this case, we can call it sensorvalue we can also call it x or y or i.

for example:

import time
from adafruit_circuitplayground import cp


while True:
    sensorValue=cp.light
    print(sensorValue)
    cp.play_tone(sensorValue,0.2)
    time.sleep(0.5)
