no value is returned

Examples

# turns pin 19 on, 21 off, and 23 on.
# This corresponds to gpio09, gpio10, and gpio11
rpi_set(pin_number = c(19, 21, 23), onOff = c(1,0,1))

toggleThesePins <- c(19,21,23)
rpi_set(toggleThesePins, 1) # turns all three pins on. onOff is recycled
Sys.sleep(1)
rpi_set(toggleThesePins, c(0,1,0)) # turns off pins 19 and 23
Sys.sleep(1)
rpi_set(toggleThesePins, 0) # turns off all pins
