Wii Remote Controlled Relay

What to Do:

1. Firstly, we need to wire it up to the pi. (Pin numbers):

1. Firstly we need to update and upgrade the Pi. Please do this step as it will minimise any issues.

$ - sudo apt-get update

$ - sudo apt-get upgrade

2. Next we will get the necessary bluetooth files

$ - sudo apt-get install --no-install-recommends bluetooth -y

3. Then get the cwiid library for interfacing with the Wii Remote

$ - sudo apt-get install python-cwiid

4. The following code should be put into the python2 editor

import cwiid

import time

import RPi.GPIO as io



io.setmode(io.BCM)



relay_pin = 4



io.setup(relay_pin, io.OUT)

io.output(relay_pin, 1)

#The relay is off when the pin is set to high



button_delay = 0.1



print 'Please press buttons 1 + 2 on your Wiimote now ...'

time.sleep(1)



try:

  wii=cwiid.Wiimote()

except RuntimeError:

  print "Unsuccessful. Run again holding buttons 1 + 2!"

  quit()



print 'Wiimote connection successful!\n'

print 'Press PLUS and MINUS together to disconnect and quit.\n'



time.sleep(3)



wii.rpt_mode = cwiid.RPT_BTN



while True:



  buttons = wii.state['buttons']



  if (buttons - cwiid.BTN_PLUS - cwiid.BTN_MINUS == 0):

    print '\nClosing connection ...'

    # NOTE: This is how you RUMBLE the Wiimote

    wii.rumble = 1

    time.sleep(1)

    wii.rumble = 0

    exit(wii)



  if (buttons & cwiid.BTN_A):

    io.output(relay_pin,0)

    time.sleep(2)

    io.output(relay_pin,1)

	

5. This code uses pin 4 for the relay pin but you can change this. To use the relay, wire one up like so:

6. The following code can be adapted to your needs but just now only shows text displaying what button has been pressed. It can be edited for any of your other projects!

import cwiid

import time



button_delay = 0.1



print 'Please press buttons 1 + 2 on your Wiimote now ...'

time.sleep(1)



try:

  wii=cwiid.Wiimote()

except RuntimeError:

  print "Unsuccessful. Run again holding buttons 1 + 2!"

  quit()



print 'Wiimote connection successful!\n'

print 'Press PLUS and MINUS together to disconnect and quit.\n'



time.sleep(3)



wii.rpt_mode = cwiid.RPT_BTN



while True:



  buttons = wii.state['buttons']



  if (buttons - cwiid.BTN_PLUS - cwiid.BTN_MINUS == 0):

    print '\nClosing connection ...'

    # NOTE: This is how you RUMBLE the Wiimote

    wii.rumble = 1

    time.sleep(1)

    wii.rumble = 0

    exit(wii)



  if (buttons & cwiid.BTN_LEFT):

    print 'Left pressed'

    time.sleep(button_delay)



  if(buttons & cwiid.BTN_RIGHT):

    print 'Right pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_UP):

    print 'Up pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_DOWN):

    print 'Down pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_1):

    print 'Button 1 pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_2):

    print 'Button 2 pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_A):

    print 'Button A pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_B):

    print 'Button B pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_HOME):

    wii.rpt_mode = cwiid.RPT_BTN | cwiid.RPT_ACC

    check = 0

    while check == 0:

      print(wii.state['acc'])

      time.sleep(0.01)

      check = (buttons & cwiid.BTN_HOME)

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_MINUS):

    print 'Minus Button pressed'

    time.sleep(button_delay)



  if (buttons & cwiid.BTN_PLUS):

    print 'Plus Button pressed'

    time.sleep(button_delay)
