• UPM Python Grove Button

root@edison:~# vi button.py

import time
import pyupm_grove as grove

# Create the button object using GPIO pin 2
button = grove.GroveButton(2)

# Read the input and print, waiting one second between readings
while 1:
    print button.name(), ' value is ', button.value()
    time.sleep(1)

# Delete the button object
del button

root@edison:~# python button.py

Grove - Touch Sensor

• UPM Python Grove Button

root@edison:~# vi touch.py

import time
import pyupm_grove as grove

# Create the button object using GPIO pin 3
touch = grove.GroveButton(3)

# Read the input and print, waiting one second between readings
while 1:
    print touch.name(), ' value is ', touch.value()
    time.sleep(1)

# Delete the touch object
del touch

          upmBuzzer.SOL, upmBuzzer.LA, upmBuzzer.SI, upmBuzzer.DO, 
          upmBuzzer.SI];

# Print sensor name
print buzzer.name()

# Play sound (DO, RE, MI, etc.), pausing for 0.1 seconds between notes
for chord_ind in range (0,7):
    # play each note for one second
    print buzzer.playSound(chords[chord_ind], 1000000)

• UPM Python Grove Light

root@edison:~# vi light.py

import time
import pyupm_grove as grove

# Create the light sensor object using AIO pin 1
light = grove.GroveLight(1)

# Read the input and print both the raw value and a rough lux value,
# waiting one second between readings
while 1:
    print light.name() + " raw value is %d" % light.raw_value() + \
        ", which is roughly %d" % light.value() + " lux";

• UPM Python Grove Temp

root@edison:~# vi temperature.py

import time
import pyupm_grove as grove

# Create the temperature sensor object using AIO pin 2
temp = grove.GroveTemp(2)
print temp.name()

# Read the temperature ten times, printing both the Celsius and
# equivalent Fahrenheit temperature, waiting one second between readings
for i in range(0, 10):
    celsius = temp.value()
    fahrenheit = celsius * 9.0/5.0 + 32.0;
    print "%d degrees Celsius, or %d degrees Fahrenheit" \
        % (celsius, fahrenheit)
    time.sleep(1)
