Hi, I'm trying to add add a +/-1 dead band to a value so the output doesn't chatter with noise. Any help would be greatly appreciated. Thanks
potvalue == (+/-1)+15:
current working codeCode:
#15 Deg if select15.value() == 0 and potvalue == 15: relayPin1.value(0) relayPin2.value(0) if select15.value() == 0 and potvalue > 15: relayPin2.value(0) relayPin1.value(1) print ("raise") if select15.value() == 0 and potvalue < 15: relayPin1.value(0) relayPin2.value(1) print ("lower")
I don't think Python has any built-in 'fuzzy arithmetic'.
Something like this might be adaptable to your needs?
Code:
from random import randintfrom time import sleepset_point = 15dead_band = 1upper_limit = set_point + dead_bandlower_limit = set_point - dead_banddef decrease(): print('Too high. Lowering.. ') def increase(): print('Too low. Raising.. ') def deactivate(): print('Within range. Deactivated.. ') for _i in range(10): current_value = randint(12,18) print(f'Current reading is {current_value}') if current_value > upper_limit: decrease() elif current_value < lower_limit: increase()# so current value must be within range - else: deactivate() sleep(2)[OT:] 5 - Nil !! Back of the net... ! (LCFC only managed 4 - Nil.)
