Here is my python code that I am using. I am trying to use a wii remote to trigger a buzzer. I thought this would be an interesting use for my old wii remote. The code that interacts with the buzzer works fine because I used an example script to test it. However, when I try and run it I keep getting this one error (see bottom). I am new to python and would appreciate any help.
import cwiid
from gpiozero import LED
import time
import os
Buzzer1 = LED(17)
Buzzer2 = LED(27)
def ConnectRemote():
os.system("rfkill unblock bluetooth")
print 'Press 1+2 On The Remote...'
global wm
wm = wiid.Wiimote()
print 'Connection Established!\n'
wm.led = 1
wm.rumble = 1
time.sleep(0.25)
wm.rumble = 0
time.sleep(0.5)
wm.rpt_mode = cwiid.RPT_BTN
def TryToConnect():
while True:
ConnectRemote()
break
while True:
buttons = wm.state['buttons']
#shutdown function using plus and minus buttons
if (buttons - cwiid.BTN_PLUS - cwiid.BTN_MINUS == 0):
print '\nClosing Connection To Wiimote'
wm.rumble = 1
time.sleep(0.25)
wm.rumble = 0
os.system("rfkill block bluetooth")
TryToConnect()
if (buttons & cwiid.BTN_A):
print 'Buzzer On'
Buzzer1.on()
Buzzer2.on()
else:
Buzzer1.off()
Buzzer2.off()
and yet I keep getting an error of
Traceback (most recent call last):
File "WiimoteLEDs.py", line 36, in <module>
buttons = wm.state['buttons']
NameError: global name 'wm' is not defined
Can anyone help? Thanks in advance
