Doh!!
The code should have been:
i = sensor_test_loops_out # Set the loop
counter to give the required time testing for the sensor
while i >= 0:
i = i -1
if GPIO.input(sensor_b):
time.sleep(sensor_pause_time)
else:
print ("Sensor B Activated")
break
Not the one below, which I tried to fix the original issue. With the
not in the line, the code goes round and round forever (because the line
is low). Without the not, the code breaks immediately before the sensor
has been reached.
What is the correct code to test for a high on a GPIO Pin?
