percentage in Micropython

Hi José.

What do you mean?

You want something similar to the map function in Arduino?

You can create your own function like this, for example:

def my_map(x, in_min, in_max, out_min, out_max):
  return int((x-in_min) * (out_max-out_min) / (in_max-in_min) + out_min)

• x is the value you want to get in percentage.
• in_min: in this case is 856
• in_max: in this case is 456
• out_min: in this case is 0(%)
• out_max: is 100 (%)

So, for example, if you want to convert the value 556, you can do it like this:

value_percentage=my_map(556, 856, 456, 0, 100)
print(value_percentage)

Tell me if this is what you were looking for.

Perfect. Thanks.
After a couple of tries the following code gives a number form 0-100:
from machine import Pin, ADC
from time import sleep
hum = ADC(0)
def my_map(hum_value, in_min, in_max, out_min, out_max):
return int((hum_value-in_min) * (out_max-out_min) / (in_max-in_min) + out_min)
while True:
hum_value = hum.read()
hum_percent = my_map(hum_value, 856, 456, 0, 100)
print(hum_percent)
sleep(0.1)

Hi again.
That’s great!
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
